Help! I’ve been dealing with these root borers in maine for the past 2 summers now, I just went out today to clean out my pots from last grow and found another one still alive in the stems after months of winter, I’ve tried everything to get rid of them but nothing seems to work, wondering if anyone has any advice or if anyone else is having this same problem
All the above. You can bake the grow medium killing every thing in it as of insect egg larva bacteria and fungi. UV-C lighting o zone kills all insect egg larva or everything single celled. < plants leaf's are single celled.
