Hi, I have purple dragon lamium and it is in full bloom right now and has a fungus that is spreading. I have alot of bees that go to the blooms and don’t want to use a fungicide on it that would harm the bees. Don’t know if the lamium will survive till the end of blooming time to use a fungicide, should I cut all the lamium back to prevent it from spreading?
Naturally this wet spring and early summer have been causing fungal diseases to flourish. Do everthing you can to keep the area dry. if you have a sprinkler system hitting the area, shut it off. I don’t know what fungal disease your getting hit with but a good organic fungicide least harmful to bees would be Seranade . Here’s another link you might find useful. I’d also get in there and start cutting it back to stimulate some new growth.
