Here in the northern hemisphere, nights are growing chillier, and it’s not unusual to wake up to a light frost clinging to car windshields and lingering garden plants. Sure, the mercury might rise when midday’s temperatures hit “balmy” levels, but that’ll change in the very near future. Those of us who are cultivating plants to last through the colder months, or have young trees that are vulnerable to severe weather, would do well to ensure that these little wonders are protected against winter’s bite.
If you’re the type of gardener who likes to grow veggies straight through autumn and into winter, chances are you already have some cloches and cold frames on hand to protect them. If not, or if this is your first year doing so, you can easily rig up some frames to protect your green babies. All you really need to do this is heavy-gauge wire or plastic tubing, and thick plastic sheeting (like a tarp). You can even cut a few hula hoops in half to create frames and then drape the plastic over them. The main idea is to create a shelter that will keep freezing rain and snow off your plants, but is shaped in such a way that nothing can accumulate on top of them. For garden beds adjacent to buildings, simple lean-to coverings can be ideal, as you can secure them to a wall, and then just use tent pegs to pin them down for easy access to your plants.
Ultimately, your goal is to keep your plants safe from heavy winds, rain, sleet, and snow, so as long as the material you’re using can shield the greens from all of this, you’re golden. I’ve used corrugated plastic, tarps, and even an old Mr. Turtle pool to protect garden plants in the past, so don’t hesitate to re-use whatever you have on hand. Ingenuity is encouraged!
If there are deer, rabbits, or beavers in your area, you might want to wrap tight-mesh wire netting (16 gauge or so) around the trunks of your saplings so the local animals won’t nibble the bark when hunger strikes.
Young evergreen trees need protection too, and in their case, one of the best ways to protect them is to wrap them. If your trees are less than four years old or so (or shorter than 5 feet), it’s best to give them a bit of added protection for the colder months.
How to Wrap an Evergreen Tree
What You’ll Need:
- Wooden stakes (1″ x 1″ should do, but don’t use little flippy bamboo ones)
- Heavy twine
- Utility knife or heavy scissors
Mulching and Mounding
Species that have been planted in the autumn, or those that die back over the colder months (like roses), need to have some extra protection to keep their roots warm over the colder months. If you have roses, hydrangeas, butterfly bushes, and Japanese maples, be sure to pile several inches of compost mixed with shredded bark mulch around the bases of these babies to ensure that they stay safe and healthy during the winter.
This mulching/mounding technique is really recommended for all manner of saplings and younger trees as well. It provides protection from temperature fluctuation, and helps to deposit an abundance of extra nutrients into the soil, which can only help to nourish your trees as they grow.
As a tip, you might wish to wait until the ground freezes before adding your mulch, so that it’s less likely to become a nest for rodents over the cooler months. You can also add a thick layer of fallen leaves and coniferous needles to perennial garden beds and around the base of shrubs to protect them from temperature fluctuations too.
