Hi all..I've been checking my bee's balm (monarda) at different hours to see what was attacking it..I just discovered a whitish/green inchworm actually coming out of it's blooms (what's left of them)..A quick search tells me the plant has been invaded by the winter moth...I also learn that this is a terrible problem in my area and an eradication program is suggested...but mostly the guidlines are for large folliage like large trees, apples, blueberries etc..not for my little bee balm. The recommendation is BT (for the inchworm stage I'm at). I"m so new to gardening and have no experience. Can BT be used on a small scale or perhaps I should just destroy the plant (the flowers are almost gone but it is still full of leaves...) Any suggestions?
