Cold weather can cause many types of problems for trees. One of those many types of problems is frost. There are quite a few ways that you can prepare and protect your trees from frost, as well as saplings from the winter frost.

How To Protect Your Trees From Frost
A fabric covering, such as natural burlap can be used to protect your trees and saplings from frost. The material in the burlap will allow moisture to escape but will still protect your tree from frost by preventing the freezing air from coming into direct contact with the moisture. Bed linens and newspaper can be used as well.
If an unexpected rain shower comes, be sure to remove the wet covering and recover your trees the next evening with a dry covering. If you know that a shower is coming, overlay the cover with a tarp. This is very important because heavily drenched cloth will not allow the tree to breathe.
Using plastic to cover your trees should be avoided by all means. Plastic will do more harm than protection. Plastic cannot breathe and trees need air to survive. Using plastic will result in trapping all moisture inside.
If the covering is light enough in weight, it can simply be draped loosely over the tree. Heavier coverings will require some type of support – you don’t want to squash your tree – tall wooden stakes can be used to support heavier coverings. Insert three or four wooden stakes into the ground around the tree and drape the covering on them as if you were making a tent. Consider using wire to keep the covering from drooping onto the tree. If you choose to use newspaper to cover your trees, be certain to pin it down so that the light material won’t blow away.
Containers can also be used to protect your smaller saplings from frost. Glass jars, milk jugs with the bottom removed, paper cups, and upside down flower pots can be used as heat traps. Only use a container if it’s large enough to accommodate your saplings, do not break or bend any part of your tree so that it may fit into a container.
The Best Protection Against Frost For Trees
Mulching is one of the best ways to protect tree roots during the winter. The mulch can range from two to six inches in depth and should be kept an inch or two away from the trunk or main stem of the trees. Check through your mulch often to be sure that moisture is getting to the soil below. If you find that the soil is dry, you will need to water it, but don’t over saturate it. Also, make sure that any cracks around newly planted trees or shrubs are filled.
Providing extra heating such as lighting can also help to protect your trees from the winter frost, but you don’t want to overheat your tree. Small Christmas lights can provide a significant amount of heat without damaging your tree.
Remember to remove coverings in the morning, to allow your trees to get fresh air and sunlight; otherwise it will fall victim to suffocation. Preferably, you should wait until the sun has been up for at least a few hours, as some of the coldest temperatures are just after sunrise. Permanently covering your trees for the duration of the winter can be harmful and is not recommended. Your trees and saplings should always be covered before the sun goes completely down, to retain heat. It also helps to water your garden before nightfall, the soil will release moisture into the air around your trees; by releasing moisture into the air around your trees at night, the air will be slightly warmer.
If frost gets to your tree, don’t remove the damaged parts. They might not look great for a couple of months, but those dead branches and leaves provide protection for the part of the tree that is still alive. Wait until spring to remove the damaged parts.
