Black spot & slugs
I'd appreciate any advice on dealing with my black spot & slug problems!
I'm in zone 5b, Indianapolis. My Don Juan climbers have a bad case of slugs & my Julia child's have black spot - round 2! I tried a variety of remedies for black spot, the Cornell treatment & corn meal dusting to no avail. I have 2 Julia child's about 3 ft apart, defoliated one & left the other. The one I defoliated has worse black spot now than the one I left the leaves on.
I'm beginning to see some cross in issues, minor black spot on the don Juan's & a few slugs in the Julia child's. is Bauer 3 in 1 my best solution for dealing with both issues?
It's starting to really warm up here (90s this week) but still raining a lot overnight. The foliage on my roses looks awful!! Please help : )
