Welcome,
@cleopatria ! That's very good advice. I have been vigilant and haven't seen signs of the little buggers again. Time will tell, though. We will probably have one more really cold spell and then take the hoops off for the rest of the season. I think this particular plant wants to be a tree and is stressed, even though it's in a huge pot. I will have to determine if it can be successfully removed from the pot and planted in the ground.
What kind of plants do you grow?
