Heresy! I need info on BT
I have that white hardy passionflower. The gulf fritillary love it. If I don't keep them picked off, they will kill it. When I do keep them picked off, it's ugly. I have a big purple passionflower on the back fence that they don't use much.
The moths have also taken to laying their eggs on my hosta. The hosta are so full, I can't find the buggers. The Dipel dust works, but looks terrible.
I'm going to buy the liquid BT. Can anyone suggest the best way to spray it? How about a spray schedule?
