After the Freeze 2021
Freeze Damage to Plants.With no snow or ice, the cold temperatures can kill the crown of the plant, especially on lawn grasses, as air temperature is colder than snow or ice temperature.* Age of plant and stage of growth: Young, recently planted trees and plants are more sensitive to cold injury.* Trees and plants that are not protected by surrounding trees and plants, but stand alone, will be more sensitive to cold injury.* Timing of the freeze : Early freezes, before the plants have had a chance to “harden-off” properly, will affect plants more than those that have been receiving a gradual “hardening-off” and have become acclimated to the cold.* Plants in pots and raised beds will be more likely to have root damage or death from freezing temperatures than those planted in the ground.Location and species play a factor in freeze damage, but I would expect the root damage to most plants in pots to be extensive.What Can We Do After a Freeze?*DO NOT prune plants or remove plants until you have determined the extent of injury.These include succulents, Agaves, tropical plants and herbaceous perennials.* A broad generalization: Plants that end up shedding their leaves have a greater chance of recovering from a freeze than those that hold onto dead leaves.They are Zone 8b, so many will likely not come back.Watch for new growth before cutting back, but in my experience, they will not come back as full and as pretty as you’d like and are probably worth replacing.Most Alocasia varieties are Zone 9 and are not expected to come back.Cut to the ground in mid-March and wait.Wait for new growth to emerge before cutting back.They are not likely to come back this year.It is ok to remove frozen growth now.If it does, it will usually come back from the ground, so if you see new growth from the base, cut it back to the ground.Plumbago: As a Zone 9 plant, only plants that are well-established and in a protected location will likely come back.Wait to cut back until you see new growth at the base.They can come back from a hard prune.Wait for new growth to show, as these can come back from the ground if you see growth at the base.A Zone 8b plant.If it was in a protected location and mulched, there may be a chance.It is not likely they will have survived this winter.Location will have a lot to do with survival.My feeling is not very positive this year about most palm trees.Sago Palms are not actually palms, nor are they likely to survive a freeze such as this, unless they are in a very protected area.Watch for new growth from the ground before cutting them back.If they were already cut back prior to the freeze, they lacked the insulation that the dead growth can give to the crown of the plant and may be less likely to come back.Wait to see new growth emerge and prune back to healthy tissue.Wait to prune until you see new growth.These trees can be cut to the ground if there is still life in them, and new trunks can be selected to form a new multi-trunk tree.Remove as little “living” growth as possible, as the plants will need this growth to produce carbohydrates for growth and recovery.They are Zone 4 trees, and unless they were newly planted or had new growth on them, they should be ok.Wait to prune until you see new growth this spring.They are normally evergreen in Zone 8 winters.I have not seen these come back from the roots.Dwarf Yaupon Holly: These Zone 7 shrubs may turn brown and lose their leaves, but I would expect most to leaf out this spring.Wait until new growth shows, cut them back to living tissue or to the ground and be patient .Remove broken limbs now but wait until you see new growth to do any major pruning.They are Zone 8 trees (10°F).Fig Trees : Do not give up too early, especially if they were somewhat protected.Indian Hawthorn: Generally cold hardy to Zone 8, these have taken a hit this year.I think location and variety will have a lot to do with which ones survive.Zone 6-7.Some of these will not come back.If they still have green growth, wait for new growth to make decisions on pruning.They do not come back from the roots, so if yours is dead to the ground and does not scratch green anywhere on the trunk, you can go ahead and remove it.Wait for new growth to prune.Oleander: Marginally winter hardy here, but often dies to the ground in hard winters.This freeze may have done them in.Wait for new growth from the ground to appear to make the decision whether to remove or cut them back.They are often frozen back or killed to the ground, but this may be the freeze that does them in.Watch for new growth before deciding on how far to cut back or remove.Unfortunately, they are also slow growing, so if they did survive this freeze, it will be a few years before they recover well.Wait to see new growth before pruning.It may come back from the roots, so wait to see new growth from the base before deciding whether to remove it or cut it back.It is possible they could come back from the roots.You can cut them back severely if showing green stems, but wait for new growth to arrive.Their evergreen branches may have broken in the ice and snow, and unfortunately, these trees do not “fill in” when parts of the tree are lost.Remove broken branches now but wait to prune back hard until danger of freeze is past in March.These can come back fairly well if cut back hard after new growth is emerging.Zone 8.Since they are deciduous and had already lost their leaves, I would expect them to leaf out this spring.Wait for new growth from the base or on the branches before cutting back.Zone 7.Other species we will “wait and watch”.Do not prune off frozen growth until you see new growth from the top.If it is an established vine, watch for new growth to decide how far back to prune.Confederate Star Jasmine: This Zone 8 vine has taken a hit in past freezes, so I would not expect any but the most protected vines to survive.The variety ‘Madison Hardy’ Star Jasmine (Zone 7) is a bit more winter hardy, so be patient to see if it is going to return.They are rated for Zone 8, and the roots may survive if planted in a protected location.I have had mine defoliate in a fairly cold winter and die back by ½ in a very cold winter.But even they may not survive this winter.Keep the trees healthy and wait.Deciduous trees will generally fare better in the winter than evergreen trees, as there is little movement of water into the trunk from the roots and the vascular system is less likely to freeze.A healthy tree is likely to recover better than a stressed tree, and trees in groupings will have been better protected than single trees.Mexican White Oak: Although this tree is rated a Zone 7 tree, it has taken a “hit” in previous cold winters.Young trees have thin bark so watch for frost cracks.Chinquapin Oak: Also hardy to Zone 5, and since they are fully deciduous, I would expect these to come through pretty well.Obviously, we did not cover all plant damage possibilities, but have tried to touch on ones that people are concerned about or that have been damaged in past hard freezes. .
