Cover with a burlap sack: After wrapping a shrub with twine, encase it in a burlap sack or commercial shrub wrap if cold, high winds are a threat. The burlap weave is wide enough that the plant can breathe, but it keeps the worst of the biting wind at bay. This covering also protects the shrub from browsing deer.
Deep water plants before ground freeze, and continue to water during winter months when temperatures remain above freezing but without precipitation, Erect physical windbreaks. Wrap problem plants with burlap or other material to protect from wind and subsequent moisture loss to evergreen shrubs and small trees.
Remember, they are an investment and contribute to the overall value and beauty of your home, too. As mentioned earlier, watering plants several hours before a freeze is the first defense against damage. During a temporary cold snap, cover entire shrubs with burlap, sheets or blankets for insulation.
Frostbite and sunscald can be damaging to your shrubs. The primary way that they can cause damage to your shrubs is through the trunk. We recommend wrapping the trunks of your shrubs before the first hard freeze and unwrapping them after the last frost of spring. You can find tree wrap at your local hardware store.
Staple the burlap to sturdy wooden stakes pounded into the ground. Keep the burlap panel a few inches clear of the plant. “A vertical panel won't collect snow,” she said. Air will circulate freely around the shrub, and the leaves will dry off after rain.
Additionally, burlap netting keeps plants warm and sheltered from all kinds of winter weather, including frost, snow, and ice. In comparison to plastic, burlap is more effective and provides better air circulation, which helps the plant breathe more naturally and efficiently.
Burlap covers protect the tender branches from splaying and breaking under heavy ice and snow while shielding the foliage from strong winds. Burlap is also more effective than plastic because it allows air to circulate through the plants.
Winter is usually the best time.
If you live in an area with distinct winters, the time when shrubs have lost their leaves and become dormant is an excellent time to prune them. Without the leaves, you can easily see the branching structure of the shrub and decide what to cut.
Know Your Plants' Cold Tolerance
Some frost-tender plants need to be covered as soon as the temperature hits 32°F, while others can handle lower temperatures and/or longer freezing periods. You'll need to look up each of your plants to verify its cold tolerance.
Take time to wrap shrubs and small trees with a winter coat of burlap for protection against cold temps. Plants at risk include those with borderline hardiness and evergreens prone to winter burn. Spray evergreens with an anti-transpirant before wrapping in burlap.
Cover Plants – Protect plants from all but the hardest freeze (28°F for five hours) by covering them with sheets, towels, blankets, cardboard or a tarp. You can also invert baskets, coolers or any container with a solid bottom over plants. Cover plants before dark to trap warmer air.
In temperate regions, most plants go dormant during the winter. This is the time of year when they've halted active growth and have hunkered down for the cold weather. Because of this dormancy, late winter and early spring are typically the best times to make any adjustments to the shapes of many trees and shrubs.
You may wonder how to protect plants from frost when they are planted in the ground? One method – which is useful for larger garden plants and shrubs – is to cover them with horticultural fleece. You could use blankets or bubble wrap, too, to create a protective cover.
Four to six inches of bark mulch, straw, or shredded leaves - especially when placed around newly planted trees or shrubs - keeps soil temperatures constant and prevents plants from heaving out of the ground due to cycles of freezing and thawing.
If you can wait until all the leaves have fallen, you will allow the trees and shrubs the ability to have better structure and strength to make it through the winter to next spring without any damage. So, put your pruners away for another month or two and let plants go completely dormant.
Yes – if you secure the plant properly. Garbage bags work to cover plants and protect from frost, but they must not be allowed to touch the plant's surface. Use stakes and supports to create a tent-like structure over the plant, which will retain warm air. Make sure the trash bag goes all the way to the ground.
If it stays cold for more than one night, can I keep my plants covered, or should I remove the coverings at some point? A. Our recommendation would be to remove the cold protection covering once temperatures are above 32 degrees.
Put coverings in place as soon as temperatures are below 36 °F (2 °C). Start the process of covering your plants for the winter when temperatures in your area fall to just above freezing in order to prepare them for the coming freezing temperatures.
DON'T prune during fall.
This can weaken and damage the plant—especially if there's an early frost.
After “how?", the second most-asked question we get about pruning is “when?” (Or, "Can I prune this now?") The rule of thumb is to prune immediately after bloom for flowering shrubs, in late winter or early spring for non-blooming shrubs (particularly for heavy pruning), and not after mid-August for any shrubs.
Spring flowering shrubs and trees.
Shrubs and trees like lilacs, azaleas, and others will grow best when they are pruned right after they flower in the spring. Avoid pruning them in the winter as it may stunt their growth.
Burlap does not allow moisture to penetrate like woven polypropylene, but it is more resistant to the deteriorating effects of UV rays. Landscape fabric can be used for landscaping, planting, walkways, paths, flowerbeds, and erosion, in addition to weed control.
In warm-climate areas like the low desert of Arizona, providing protection from freezing temperatures may prolong the growing season. Peppers, tomatoes, eggplants, and basil are a few plants that, if protected from a freeze, may continue to produce and grow. Other tender plants will need to be replanted in the spring.
