Jumpstarting Spring: Starting Seeds Indoors

After enduring months of bleak outdoor landscapes, the long ramp up to spring can be tough on gardeners — leaving us itching to get our hands in the dirt and just plant something. Inhospitable as the outdoors may still be for tender plants, there is a tried and true antidote for gardeners’ particular brand of spring fever: sowing seeds indoors.

Annuals get a great head start on flowering when they begin life indoors. Pictured above are ‘Profusion’ zinnia, which are very easy to grow from seed–even for beginners.  (Photo by Elena Kyuchukova)

Cold Comfort: The advantages of seeds

Starting seeds indoors offers some significant benefits.  For one thing, buying seeds is a lot cheaper than buying plants, allowing you to indulge in those dramatic mass plantings and deep drifts you’ve been dreaming of –without breaking the bank.  For a minimal investment in a packet of seeds, you can populate your garden with plenty of new plants –and have enough left over to share with friends and fellow gardeners!

Seeds also afford you the opportunity to try out new or exotic varieties that you won’t find in mass market outlets or local garden centers.  Retail space is always at a premium, but especially in springtime. So plant purveyors tend to focus on a limited number to “regulars” that they know will sell.  By raising your own plants from seed, you give yourself a wider palette of plants to work with.

Given our somewhat short growing season here in the Mid Atlantic, jump starting plants inside can also nudge slow starters into earlier bloom and allow vegetables that wouldn’t ordinarily grow in our region enough time to mature.

The sleeping potential contained in each seed has the power to transform your garden –and your outlook– without blowing your budget.

In addition to all these good and practical reasons for starting seeds, if you ask veteran seed-starters why they do it, they will often tell you that there is just something magical about planting a small, hard fleck of possibility and watching it grow into a supple, living shoot.  No matter how many times you’ve experienced it, they’ll say, it never ceases to amaze.  So, if you haven’t tried it before, now is great time to start.  And if you have, well… it’s time to get growing!

Sow What? Plan before you plant

When it comes to choosing which plants to grow from seeds, the sheer volume can be overwhelming.  And every year, new and exciting hybrids and varieties are added to the mix.  Combine this with page after page of luscious photos and glowing descriptions, and you have a recipe for overbuying.  So, if you’re new to seeds, starting small is key.

But it behooves both rookies and veterans alike to take a close look at their garden before buying, and come up with some kind of plan – one that takes into consideration how much space you have and the conditions in your garden. (For help with planning, see: Basics of Flower Gardening and Planning a Vegetable Garden  from Rutgers.)

And don’t forget to take into account how much time (and space) you have inside for growing all those seeds…

Once you’ve established your limits, there are as many ways to research seeds  as there are gardeners. Whether you enjoy pouring over seed catalogs, watching gardening shows, or developing your Pinterest board–the time you invest in planning your seed-starting endeavor will end up saving you time, effort and cash later on.

Don’t pitch those packets! Seed envelopes contain everything you need to know about how to sow and grow the seeds inside.

Pushing the Envelope: Reading seed packets

As you peruse the wide selection of seeds available online and in garden stores at this time of year, take a minute to read the packets and/or accompanying plant descriptions. You’ll find they contain a lot of important information, some of which might be unfamiliar to gardeners new to seed starting.

When selecting vegetable varieties for example, check packets for the number of days until harvest to be sure your choices will ripen before frost. Many long-season vegetables must be started indoors in early spring. Similarly, many annual flowers need an indoor start if they are to bloom during the summer.

For detailed info on deciphering seed-starting lingo, check out: How to Read Seed Packets and Information on Seed Packets.

To get the most out of the information provided on seed packets, there are several pieces of information you need to know. One is your USDA Plant Hardiness Zone, which often appears as a map with designated planting dates. Mercer County gardens are in either Zone 6b or 7a, depending on their location. To find out for sure which zone your garden falls into,  just enter your zip code on the USDA website here: Find Your Plant Hardiness Zone.

Timing is Everything: Picking the perfect time to start seeds

When it comes to determining the proper time to start your seeds, there are two important dates to know:

  1. The average LAST frost date for your area ( the date in the spring when you can finally be sure that you won’t get another frost)
  2. The average FIRST frost date in your area (the date in the fall when frost is likely to start killing sensitive plants).

Here in Central New Jersey, our average last frost date is May 10.  To be on the safe side, a good rule of thumb has always been to wait until after Mother’s Day to plant seedlings outdoors.

Our first frost is usually on or about October 15which is important to know when growing certain vegetables from seed, to make sure they’ll have enough time to fully ripen before frost. (Rutgers Fact sheet Starting Vegetable Seeds Indoors lists how many weeks pass between seeding indoors and when transplants are ready for planting in your garden.)

Starting seeds at the right time helps seedlings develop into sturdy, well-branched plants, like these coleus, (Plectranthus scutellarioides.) Since coleus likes warm weather, plants started indoors should be planted outside 1-2 weeks after the last frost date. (Photo by Elena Kyuchukova)

A common mistake new seed starters often make is starting seeds too early.  If started too soon,  plants tend to have spindly growth and may outgrow their containers before it is warm enough to transfer them outdoors.  The goal is to produce stocky, moderately sized plants that will recover quickly when planted outdoors.  To achieve this, it’s critical to start seeds at the proper time.

It All Adds Up: Seed starting math

To determine when to start your seeds, look on the back of your seed packet for the average number of weeks required to grow indoors or transplant outside, as well as the number of days to germination.  (These two numbers are often listed as a range.)  Add  the time required for germination and time indoors to transplant.  Then, on a calendar, count backward the appropriate number of weeks from your last frost date.  The result will be the appropriate date for starting that type of seed.  For an example, see below:


‘African Sunset’ petunias

The Annual Garden at Mercer Educational Gardens in Pennington  will include ‘African Sunset’ Petunias grown from seed this season.  

To determine the best time to start them indoors, Mercer County Master Gardeners took the “8 weeks indoors” listed on the back of the seed packet, and added the listed “7 days needed to germinate,”  for a total indoor growing time of 9 weeks (1 week to germinate + 8 weeks indoors.)

They then counted 9 weeks back  from our last frost date of May 10, and arrived at a seed start date of March 8.

 


Down to Earth: Soil for starting seeds

Seeds should be planted in clean, fine potting soil– generally no deeper than the width of the seed itself. (Photo by Margaret Montplaisir)

Choosing the right potting soil is another important part of successful indoor seed starting. The most convenient choice is to purchase a commercially available soilless mix, one specially formulated for starting seeds. Most contain a mix of peat moss, perlite, vermiculite, and usually some fertilizer. Soilless mixes are also sterile and reduce the risk of losing seedlings to soil-borne diseases.

You can create your own seed starting mix too (a recipe is contained in Rutgers fact sheet Starting Vegetable Seeds Indoors ) but know that using soil directly from the garden is not recommended, because it may contain insects, weed seeds, or disease organisms that could damage or kill young plants.

Pot luck: Choosing containers for seedlings

Peat pots can be planted directly into the garden, which keeps developing roots intact. But make sure the edges of the pot do not stick up above the soil, since the exposed area will act as a wick and cause moisture to evaporate rapidly from the pot.

Almost any clean container can be used for starting seeds provided it’s at least 2 inches deep and allows for good drainage.

Some gardeners like to save money by reusing yogurt containers, milk cartons, aluminum pans, and clear clamshells from the produce department. A 6-ounce plastic, non-waxed, paper drinking cup also makes an easy and inexpensive starter container.  Before using for up-cycled containers for seeds, be sure to poke some holes in the bottom to allow for proper drainage. Otherwise, soil can become saturated, which encourages diseases in the seedlings. One way to minimize the chance of overwatering seedlings, is to be sure to start them in small containers.
In addition to using recycled containers, there are a lot of choices available for purchase, including:

  • Plastic trays (flats) that are 10.5 in. X 21 in. X 2 in. deep
  • Small pots and pellets that expand when you add water made of compressed peat
  • Plastic cell packs (inserts or market packs) with square or rectangular plastic cells joined together and sized to fit into a plastic flat. The individual cells range in size from ½  to 4 inches in diameter
  • Plug trays in sturdy one-piece plastic flats that are divided into individual cells

Hit the Dirt: Planting how-to’s

Regardless of the type of container you choose, fill it three quarters full with seed-starting mix and sow the seeds. Be sure to place seeds at the planting depth recommended on the seed packet. Plant one or two seeds per individual container or, if using flats, you can plant in rows that can be thinned or transplanted into individual containers following germination.  Be sure to label the flats to avoid confusion, using a pencil or water-resistant marker.  (It’s easy to forget which sprouts are which.)

When seeding a tray or flat, plant in shallow rows 1 to 2 inches apart. Sow the seeds uniformly and thinly in the rows. Be sure to label each row right away with plant type, variety and date of planting.

Water Ways:  Keeping seedlings moist

Once the seeds have been planted, the container should be watered from the bottom by placing it in a shallow pan of water and waiting until the surface of the mix is moist. This method avoids overhead sprinkling, which can carry away smaller seeds.  The pot should then be removed from the pan and allowed to drain.

It is important to keep the soil moist at all times, watering again from the bottom as necessary since seeds and seedlings are extremely sensitive to drying out.

Placing the container in a clear, plastic storage bag until seedlings emerge will help keep the soil moist. This will also increase the humidity and help keep temperature stable. The plastic should not be in contact with the soil, though. Be sure to remove the plastic cover as soon as sprouts appear.


A Fungus Among Us: The danger of damping-off

While seedlings should be kept moist, they should never be kept continuously soaking wet, since this condition can lead to “damping-off,” a fungus disease that is deadly to young plants. The fungi that causes the disease – –PythiumPhytophthora and Rhizoctonia– – can quickly kill an entire batch of seedlings.  If an infection occurs, dispose of the plants and growing medium, wash containers and tools to remove any debris, and soak them for 1-2 minutes in a solution of 1 part chlorine bleach to 10 parts water.  Then rinse with clean water.


The  Heat is On:  Keeping seeds warm

The consistent warmth provided by electric heating mats –like the black and green one visible above– can be very beneficial to certain types of seedlings, leading to better germination rates and stronger root systems. (Photo by Ellen Kellich)

In addition to moisture, seeds need warmth to germinate. For the best results, keep seedling pots in a location that is between 70 to 75 degrees F.  Spots like the top of a hot water heater or the top of the refrigerator offer enough warmth to aid germination.

Or you can purchase heating mats that are specially designed keep germinating seeds warm. You can find them in larger garden centers, and online. Be sure to only use mats that are designed for seed germination and follow manufacturer’s directions carefully. Using a thermometer or thermostat in conjunction with seed mats will prevent overheating seeds and soil.

Let there be Light: Simulating spring sun

Better results stem from growing seedlings under fluorescent lights( rather than to relying on natural light alone.) Lights should be positioned very close to seedlings –2 to 4 inches above them is best. (Photo by Ellen Kellich)

Once the seedlings emerge, remove plastic bags or covers and give the seedlings as much light as possible so they can grow into stocky well-branched plants.

While it’s possible to grow seedlings without supplemental lighting, the fact is: you will have much better success growing under lights compared to relying solely on natural light from windows.

There are many types of lights that can be used to grow seedlings indoors. They range from fluorescent “shop lights” to the newer LED light systems.  What’s best for you depends on your space and budget.  For the most part, standard fixtures with a combination of cool white and natural daylight tubes provide adequate light are relatively inexpensive.

It’s important to keep lights no more than 4 inches above the tops of your seedlings. As close as 2 inches is ideal. Lack of light is the major cause of elongated, skinny stems which results in frail and floppy plants. Hanging lights from chains or pulleys makes it easier to keep them at the optimal distance as plants grow.

Plants need 12 to 16 hours of light daily, but don’t leave lights on all the time.  Plants need some dark periods too for proper development. Adding an inexpensive timer to your light set up can help ensure plants get the right amount of light and darkness.

Numerous plans for easy-to-build light stands are available online, including this from University of Maine’s Cooperative Extension: Bulletin #2751, Starting Seeds at Home  and this Do-It-Yourself PVC table-top light stand from the University of Maryland.

Room to Grow: Moving seedlings to larger containers

As seedlings grow, they must be potted up into larger containers to give them enough space to develop. Avoid the common mistakes of keeping seedlings in flats too long, which can hinder their growth.

The ideal time to transplant young seedlings is when they are small and there is less danger of setbacks from root shock. This is usually about the time the first “true leaves” appear above or between the “cotyledon” or “seed” leaves, which are the first leaves to appear. (The seed leaves  are visible in the photo below.)

Dig the seedlings out of the mix with a small trowel or spoon. When transplanting, always handle the seedlings by the leaves, being careful not to damage the fragile seedling stem or root system. Then transplant them gently into their new containers.

When planting in flats, like these parsley plants, seeds can be planted in rows. Once each plant has four leaves, thin seedlings by pulling out all but the healthiest plant. (Photo by Ellen Kellich)

Ready for the Great Outdoors: Hardening off

Seedlings are ready to transplant outdoors when their roots have filled the pot in which they are growing. Check instructions on the seed package for any specific details on when and how to transplant.

Before planting the seedlings in your garden, allow at least a week for them to become adjusted to the outdoors. Each day, place them outside in a sunny spot for a few hours, and then bring them back inside. Gradually increase their length of time outside.

It’s best not to set out tender seedlings on windy days or when temperatures dip below 45 degrees F.  Even cold-hardy plants will be hurt if exposed to dramatically colder outdoor temperatures.

After a week, seedlings should have adjusted sufficiently to the outside world to be ready for planting in the garden. When planting seedlings outside, pay attention to the spacing indicated on the seed packet.

Seedlings should be planted at the same depth at which they were growing indoors, except for tomatoes, which may be planted deeper.   For more info on planting vegetable seedlings, see the Rutgers fact sheet Planning a Vegetable Garden FS129.

If possible, try to transplant on a cloudy day to minimize wilting or transplant shock. Once the seedlings are in the ground, firm the soil around the root ball, and water immediately with a solution of water and starter fertilizer.

After about 6 weeks indoors, these beautiful kale plants are ready for the real world.  (Photo by Elena Kyuchukova)

Garden Wars:  Dealing with Deer

 

IMG_0681When it comes to garden pests, deer have long been Public Enemy No.1 here in central Jersey. Their unrelenting browsing disfigures trees, reduces shrubs to nubs, and obliterates our lovingly-tended beds and borders. With deer populations soaring and native habitats shrinking, deer have become a source of constant frustration for many gardeners.

So what’s a Garden State gardener to do about this gnawing problem?

While there is no simple formula for battling deer damage, don’t raise the white flag just yet.  Try some of these deer defying tactics instead.  They might be all you need to make peace with the local herd.

Don’t give up on gardening just because deer have been snacking on your landscaping.  While nothing is foolproof, there are strategies that can moderate deer damage.

Dine or Dash? It Pays to Plant Smart

To help New Jersey residents make smarter choices about the plants they install in their gardens, the folks at Rutgers Agricultural Experiment station have put together the ultimate tool for gardening in deer territory.

They’ve indexed hundreds of popular plants—all of which grow and thrive in our area– and rated them by deer resistance.  But the best part is: you can tailor their list to unearth exactly the type of plants your garden needs!  Were your annuals annihilated?  Your perennials pulverized? Using the Rutgers online tool, just search for “annuals” (or perennials, trees, shrubs, etc.) and voila: a list of deerly-detested plants pops up.  Or maybe you’re considering adding a certain plant to your garden and are wondering if it is destined to be deer fodder?  You can search for it by name (using either the common name or the Latin name) and see its degree of deer delectability.

So why not do a little “browsing” of your own for a change!  Click the link below to delve into Rutgers’ deer diet database:

Azalea

Now that you’re armed with an arsenal of deer-distained plants, does that mean any plants tagged with the dreaded “Frequently Severely Damaged” designation are off limits?  Hardly. It just means they’re best planted with a little “additional protection.”  What kind of protection?  Read on…

On Guard: Fencing 101

The most effective, long-term solution for thwarting Bambi and his plant-munching kin is definitely fencing. No other tactic is as successful at eliminating deer from the garden.  That said, fences only work if properly built and maintained.

img_0577

Fear the Fence: Even though deer can easily jump fences under 8 feet tall, they are normally hesitant to jump into small plots, or spaces that don’t allow them to see their landing spot–for fear they won’t be able to get out. (Photo by Margaret Montplaisir)

To successfully thwart deer incursions, fences should be at least 8 feet high, kept taut, and have no gaps.  And it goes without saying that the fence must completely enclose the area you are trying to shield. Forget about fencing only one side of the property or thinking a small or remote break will go unnoticed. If there are any open sections, rest assured deer will find a way through.

gatewire-992-jpg

An obvious–though commonly missed– component of effective deer fencing is to make sure gates are always kept securely closed. (Photo by Anne Zeman)

On the Fence About Which Enclosure You Need?

There are many types of deer fencing available–from solid stockade barriers to nearly invisible plastic mesh screens.

lowerwire-990-jpg

Wire fencing is long lasting and highly resistant to damage. It is also expensive to purchase and install, but can be a cost effective way to protect valuable plantings. (Photo by Anne Zeman)

Which style you choose depends on: your budget, the size of the area you are trying to protect, and the level of deer damage in your area.  Also, if your property is in any way hilly, preventing gaps can be a challenging but necessary issue to address.

Regardless of the type you select, deer fencing must be properly anchored to the ground. Unlikely as it may seem, given the choice, deer are more likely to crawl under a fence than to jump over it.

Deer are opportunists and will push through any breach they find, so it’s important to examine fences frequently and fix any holes or gaps.

Fencing made of plastic netting is generally less expensive, and less visually obtrusive. (Photo by Anne Zeman)

There are some types of deer fencing that you can install yourself, but others–like high-tensile wire fences—require special skills and might be best left in the hands of experienced contractors.

While deer fencing can be expensive, you may find that the one-time cost of a permanent 8-ft. fence is well worth the price given the peace of mind and years of damage-free gardening it can provide.

To learn more about deer fencing, see:

High-Tensile Woven Wire Fences for Reducing Wildlife Damage

How to Build a Plastic Mesh Deer Exclusion Fence

Low-Cost Slant Fence Excludes Deer from Plantings

 

Amping up Deer Deterrence

Another type of deer exclusion is electric fencing. Built specifically to handle deer, high voltage electric fences can prove very effective in keeping them out. As with any fencing, proper installation and maintenance are key.

Before you consider this type of exclusion, you should know that the use of electric fencing is generally not an option in residential areas, although it is often permitted in rural locales.

portable-electric-fencing

Portable electric fencing consists of conductive strands of stainless steel and nylon cord which are kept separated by plastic supports (b) a foot apart to form a “mesh-like” barrier. Fiberglass posts (c) are coupled with 5-inch steel spikes to allow them to be hand pushed into the ground to support the fence. (Illustration from Rutgers’ Portable Electric Fencing Fact Sheet #888)

Under the right circumstances, electric fences can be both effective and cost-efficient.  But for safety and effectiveness, it’s best to have electric fences constructed by an experienced contractor.  The price of electric fencing can vary widely depending on the style of fencing used and the size of the area that needs protecting, so it pays to shop around.

For best results, electrify the fence immediately after installation and keep it electrified at all times. If an electric fence is turned off for several days, deer may learn to go through it.

Stop Gap Measures: Portable Electrics 

In addition to permanent electrified fencing, there are also portable electric fencing systems that can provide temporary protection for crops, gardens and landscaping. Most often used in smaller areas, they offer the advantage of being easy to move around, dismantle, and reassemble as needed.

For more information, download Rutgers factsheet FS888, Portable Electric Fencing for Preventing Wildlife Damage

img_0412

Deer fences of any design must be checked regularly. Repairs to damaged or broken fencing should be made promptly to prevent any gaps that might allow deer to squeeze through. (Photo by Calleen Parson)

Net Gains: Protecting Individual Plants

Electrified or not, the biggest drawback to full-on deer fencing is cost. But in areas where deer density is less intense, a more cost-efficient approach might be to only “fence in” those plants that tend to get hit the hardest. Young trees, for example, are particularly sensitive to deer damage and often do not survive intensive deer browsing.  Individual trees can be protected from damage by surrounding them with tree shelters or wire cages that keep vulnerable trunks and lower branches out of the DMZ (Deer Mutilation Zone.)

img_0400

Young trees are particularly sensitive to deer damage. Protect trees below “browse line,” from ground to lower limbs.

You can remove this type of fencing once trees have branched beyond the reach of deer, or you can leave it in place to keep bucks from using young trees as their personal scratching posts when removing the felt from their antlers in the fall.

Admittedly, tree shelters and wire cages are not the most attractive additions to a home landscape, but if the damage you’re experiencing is extensive enough, and the plant you are shielding is important enough, you may be able to “look past” the wiring in order to keep your prized plant alive.

For the Birds: Help for Low Growing Plants

Another low-investment way to protect vulnerable plants and shrubs is through the use of flexible plastic or “bird” netting. Like wire caging, it too provides temporary protection for vulnerable plants but it is often less noticeable (especially from a distance) than enclosures made of hefty metal wire.

Lightweight and less substantial than wire mesh, plastic netting tends to works best in areas where deer browsing is relatively light.  It is typically used to cover low-growing shrubs, groups of plants, or seasonally-harvested berries and fruit.  To keep netting from blowing away and to avoid gaps, use wooden stakes or zip ties to anchor the netting over plants.

For additional information on  the use of bird netting, as well as other types of deer fencing, see: Deer Damage Management Techniques —  Exclusion Methods.

Scent-sible Solutions: Using Deer Repellents

If exclusion is not a viable option for you, repellents can be a comparatively low-cost way to steer deer from your prized plants.  Repellents basically use either an unpleasant taste or odor to teach deer to avoid the yucky stuff in your yard and search out less noxious noshes elsewhere.

Repellents come in a variety of forms –from homemade concoctions to commercial ready-to-use sprays. Some are applied directly to plants and repel deer by taste. Others deter deer by scent, and are meant to keep deer from a specific area rather than a specific plant.

img_7956

One deer repelling technique used by Master Gardeners at Mercer Educational Gardens, is to string absorbent barrier tape around the perimeter of each garden. The tape is then sprayed with deer repellents. Stakes ensure that the tape stays taut and is held right about deer nose level –30 inches from the ground.

Regardless, of the type or technique you use, repellents are most effective when applied before damage occurs. They also work best over relatively small areas when deer populations are on the low side.

Re-application is key for all repellents, since they tend to wear off over time and wash off quickly with rain and snow.  But even with good upkeep, deer tend to get used to repellents over time, so it’s a good idea to switch to a different type of repellent — or at least one with a different active ingredient–at least once a year.

Many gardeners find that a combination of odor- and taste-based repellents provide the best benefit.  For more information see:

Deer Control in Home Gardens – Repellents

Using commercial deer repellents

Repellents can reduce damage, but will not entirely eliminate damage. Deer will eat just about anything when food sources are limited.

Scare Tactics

Another strategy that might be worth a try involves devices that attempt to spook deer.  Things like motion-activated sprinklers, strobe lights, and even radios have been known to send deer high-tailing for more peaceful parts.

img_0594

Skittish by nature, deer will often turn tail and bolt when faced with loud or startling sights and sounds.

But more often than not, scare tactics only work for a short period of time.  After that, deer become accustomed to them and don’t even flinch. Sometimes though, scare tactics can give you just enough protection to allow a young plant to become established or a specific crop to be harvested.

A word to the wise: When it comes to using noise-makers, permits may be required in some areas. Check with local ordinances before installing them and–at the very least–clear it with any near-by neighbors.

 Yelp Help: Using Dogs to Control Deer

Deer prefer calm, quiet areas for grazing– so a loud, barking dog in the yard can sometimes be enough to drive them off. Dog deterrence is most effective when combined with those “invisible” dog fences that allow pups to freely patrol an area and harass  intruders as they attempt to move through.

Of course, dogs are only effective at discouraging deer when they are out and about at the same time as the deer. Given that deer often feed during the wee hours, in order to successfully ward off any late-night intrusions, dogs must have access to the yard at all hours.

Good as dogs can be at sending deer packing, in practice, a combination of deterrents might be more effective than relying on Fido alone.

img_0621

Dogs can be very effective at repelling deer, provided they spend most of their time outdoors– and are actually interested in driving off deer. (Some dogs are more “vigilant” than others.)

Committing to Co-existing with Deer

IMG_0586

Deer are a fact of life here in New Jersey, but by experimenting with different deer deterring strategies, you can enjoy your garden AND co-exist with any doe-eyed visitors that may wander your way.

Regardless, of the type of deterrence you deploy, when it comes to dealing with deer there are no quick fixes.  So it pays to pick your battles.

Reconsidering how much damage you can live may be the first step in deciding which of the above methods will work best for your yard.  It may be worth approaching deer damage with the same attitude you adopt when addressing other garden challenges– like weeds, insects or even noisy neighbors.  Sometimes just changing your level of tolerance can go a long way toward a more peaceful gardening experience.

It may also help to know that things aren’t always as grim as they sometimes appear:

  • Even though deer damage can look devastating in mid-winter and early spring–when browsing is at its most intense–in many instances, plants will eventually rebound.
  • Corrective pruning can often minimize tree distortion; and, in the case of antler damage, as long as the bark has not been rubbed off around the entire trunk, there’s still a chance that the plant will be able to heal itself.
  • In the spirit of live and let live, there may be some circumstances in which you can plant some “extras” that you wouldn’t mind “sharing”

 Balancing Those Near and Deer
