luvgardening,
I'm not sure, as I have so many of the
plants and by the time those catapillars are devouring the leaves, there's the cirles and pathes through them, so the catapillars eat the evidence and I'm content with the
seed pods I get as there is 1 million
seeds it seems like, and I have to keep finding places or good homes for them, as you're not suppose to intermix the colors or varieties as they interbreed as I understand it. So, I've really never done much with them myself. Supposedly you can clip off the offending leaf or leaves and that helps take care of it, but I loose half the
plant over night so I leave what is left of those leaves so they can have some photosynthesis.
(when the cabbage worms first appear, then I start squeezing them, I am a no~chemical type)
I enjoy my columbines, in the
spring, they are lovely and bring back memories of my grannie, the purple ones I have were her's originally.
I'll send you some info on them, hope this helps.
