Got Snow? Don’t Worry – Your Garden’s Okay

This past week has been full superlatives when describing the snow that has fallen – unprecedented and disastrous (Hello, Texas), unlike anything they’re used to (Hello, Seattle), etc. For millions of Americans, this is something they’re not accustomed to, and that alone can be scary. For others, snow is a regular visitor in the winter, but this year there’s been so much more of it than usual. The snowfall is unusual all over –Russia is staggering under their massive amounts (more here) and Saudi Arabia has been uncharacteristically hit (see some bewildered camels here ).  It’s enough to worry anyone who’s been looking forward to a spring garden.

The truth is that snow is not as disastrous for a garden as it may seem at first glance, although it does carry some risk. Let me lay it out in pros and cons:

PROS – 

• Fresh snow works like a cozy blanket as it covers plants. Snowflakes contain tiny pockets full of air, and when they accumulate on the ground they heap together and form larger and warmer air pockets. This air can prevent the soil from freezing and allows roots to continue thriving and taking up water to supply the plant. This is especially true in those areas where sudden low temperatures are not expected to last a sustained amount of time.

• Snow forms a barrier to keep drying and damaging winter wind from bark and delicate plant leaves. 

• A layer of snow can protect a plant from the worst effects of the freeze-thaw phenomenon. This is when ice causes the ground to expand when it freezes and constricts when it thaws. The end result of this can be favorable for the soil by creating a lighter, more friable soil that new plants in spring and overwintering bulbs will appreciate. In the worst case, freeze-thaw can turn bulbs into mush and uproot plants. A layer of warming snow can reduce this likelihood.

• Snow holds water in the soil and, as it melts, it slowly waters the area. This is especially beneficial for emerging perennials. 

• There is an old saying that snow is “Poor Man’s Fertilizer”, and, like many old sayings, it turns out to be true. As snowflakes make their long fall down to earth they accumulate nitrogen and other micronutrients along the way. These elements are then slowly released into the soil as it melts. Even dormant plants can absorb nitrogen deposited in this way.

• Snow can enhance the sunlight given to plants. The brightness of the snow causes light to shine all around and even down through it so that plants can continue to photosynthesis through the darkest months of winter. 

• Snow cover can hide the egg cases and chrysalis of many beneficial insects and moths and protect them from predation.

CONS – 

• The weight of snow on branches and small trees can quickly become too much for them. Branches can split or break off entirely, and trees can collapse or uproot. To avoid this, clear snow off your growing things as soon and as often as possible. Don’t forget to clear it from the roofs of any structures that are next to your trees and plants. A mini-avalanche from your garage roof onto your landscaping along your house could be tragic. 

• As the snow melts, watch for ice pools that can form around trees and plants. If the temperature falls again, you can find yourself in that freeze/thaw cycle that many plants cannot recover from. If you see this happening, you’ll need to get out there and get some drainage going. If you have to make some furrows where there weren’t any before, don’t hesitate. As long as you keep your plants alive, you can tweak the aesthetics later. Now that you can see how winter affects your garden, this would also be a great opportunity to develop a better year-round garden plan, with plants’ placements that suit their needs all year round. 

• Snow creates cover for hungry animals like voles, who work underground, but also serves as a step up for those that prey on bark, branches, and leaves. When the snow hides their close-to-the-ground food sources, those lighter creatures can easily scamper up it to feast on plants. Be watchful for tell-tale tracks and take gentle steps to keep them away from your plants.

• In areas where there was drought the previous summer (which is almost everywhere nowadays), trees and shrubs that go into winter drought-stressed may have little left to fight off the cold. While there is little that can be done once the cold has arrived and the snow has fallen, this should be a reminder to prepare your plants for tough winter weather by first preparing them to get through a tough summer. For more on this, check out this article.

• Snow can provide a safe place for beneficial insects but is also works to protect less desirable entities like snails, slugs, overwintering insects, and molds. Keep a careful eye on what emerges not just after the snow, but as everything truly warms up in spring. Remember that early and pro-active treatment of pests and pathogens is the most effective treatment overall, so an early problem does not have to develop into a mid-season infestation. 

The effects of a snowstorm are considerably different than an ice storm. There is not a whole lot of positive to be found after one of those (read more here). So, as much as you are able, if you’re only dealing with snow try to enjoy it while it lasts. And if you want to keep the kids busy, send them out to knock some snow off the trees.

Stay Warm.

A Busy September in the Garden

Now that Labor Day is in the rearview mirror and all the kids are back in school, people everywhere are amping up for the busy fall season. This is especially true for gardeners. This time of year is chock-full of gardening and taking-care-of-outside chores. As most serious gardeners know, September is not the end of the season. In reality, it is the beginning. What you do between September and late November will help determine how heavy your workload is for next spring.

Many gardeners are well on their way to having a fall garden by now. Depending on where they live, the planning and prep has been done and they have already planted or are ready to move on to planting. Those winter greens and vegetables will be very welcome as fall turns to winter. Here is a delicious-sounding salad that features Brussels sprouts, pumpkin seeds – and a surprise touch.

But what if you are not doing a fall garden this year? If you want to plant in the spring or just want a healthy backyard environment for your warm weather enjoyment, there is a lot that can be done now to make that happen. Putting in a little time now can save you time, money and worry as you come out of winter next year.

Plant a tree: If you are not up to going the whole fall garden route but still want to get your hands in some soil, consider planting a tree. Every day is a great day for a tree, but September through November is the ideal time for planting one. This will give their roots time to establish before hard freezes and allows them to concentrate their energy on growing roots before they put out leaves in the spring. The key to success with this schedule is to encourage strong and healthy root growth and to water deeply. We recommend Root Build 240 for the roots. For more information, check out our tree planting blog here.

Apply Beneficial Nematodes: We strongly encourage fall applications of these microscopic organisms to control pests that overwinter in the soil. We have beneficial nematodes that can control a myriad of pests, including various beetles, ticks, fungus gnats and caterpillars. Apply some now and apply again in the spring to knockdown any pests that got away. These fascinating creatures do amazing unseen work in the ground. We have a ton of information on them here. And they are on sale through September!

Move your garden to containers: If you have some plants that you’d like to keep going or some favorites that you like to have around, put them in containers. It will be easier to protect them (and yourself) from the elements. Put them close to the house or on a porch for easy access and raise them off the ground; this will keep them from becoming waterlogged in the wetness of fall and winter. Here is a video with some tips on fall container planting. 

Lawns: Your lawn will enjoy some dethatching, fertilization and aeration at this time of year. And, while you’re at it, you may as well go after those stubborn perennial weeds. Weeds draw up nutrients in the fall to prepare for winter; if you apply herbicide now it will be drawn up as well. Corn Gluten Meal may work well for you; it will fertilize as well as kill weeds. Check out our blog on this versatile corn by-product. We also have many other excellent weed control options here.

Clean out sheds, greenhouses and cold frames: Now that the weather is cooling off (except here in Southern Arizona), get out and clear up the clutter that it was just too darn hot to deal with over the summer. If you are planting again, you will want this clean slate. If you are not, cleaning now will give you a chance to move items that shouldn’t be out in the cold and free you from spending your spring days going through debris from the year before. Be sure to empty and clean out all the compost and decaying plant matter from old pots and containers to keep overwintering pests from finding a home there.

Trim things up: Help your plants by maximizing light sources as we move into the darker months. Remove thick or overhanging vegetation around your garden, greenhouse or patio. To encourage pumpkins to ripen by Halloween, trim up any leaves and/or re-direct vines that may be shadowing them. If you have apple trees – lucky you – run the mower under them so you’ll be able to easily spot any windfalls.


Compost: Not composting? Start now to take advantage of falling leaves and dead plant material. If you are already composting, you probably know already that the bounty of leaves in the fall are an excellent addition to a compost pile. Check out our composting products here.

Plan for beauty: Now that you have a trimmed up and cleaner yard environment, and a plan for all the fallen leaves that someone will have to rake up, it's time to plant bulbs for next year’s enjoyment. Stick them in now and when they start popping out next spring you will be so glad you did.                                                                 
Above all, get out and enjoy this time of beautiful time of year. The sunny, cool days and crisp nights of autumn are something that this Virginia native gets homesick for every year at this time.
