Will my frozen plants survive or do I need to pull them all up?
Pictured above is a frozen 'Clara' Indian Hawthorn in front of the Chiles restaurant in Conroe, Texas. Notice the new growth coming out from the bottom. Everything above that is obviously dead.
For us plant lovers the only thing worse than being locked in and not being able to get the plants we want is to have them all freeze heavily and see years of growth disappear in a couple of days.
The following suggestions are generalizations and best practices. However, these are rather subjective, as your results may vary.
For all of your crispy plants out there, you should start seeing some new growth, at least from the base of the plant. This should be more evident if you have already trimmed them back, as pruning will stimulate new growth. If you haven't yet pruned them back, cut them back til you get to green wood. If you can find green wood then there is a good chance that these plants may come back. If you have to go all the way to the base of the plant to find green wood then there is still a chance that it may come back from the root system however, it may be a while before you see a semblance of the former occupant of that spot. Things that we suspected were dead forever appear to be coming back and some things that we thought would come back might be headed for the plant graveyard.
If they were mushy after the freeze, you should have cleaned them up by cutting them to the base and removing all the mushy plant material.
There is no way to give you a list of plants that absolutely will or will not come back from the Snovid-21 event.
At the beginning of April, plant supplies were getting thin. Don't wait too long to find replacements.
