Question
How big should a tomato plant be when it is safe from cutworms?  We put cans around our seedlings and were wondering when it would be safe to remove them?

Answer
Dear Frances,
I am not sure when it is safe to remove the cans, but I can recommend diatomaceous earth around the tomatoes for their protection.  It doesn't hurt the plant, but worms do not do well in the environment it creates.
I wish you well with your tomatoes.
Kind Regards,
Kindred
