What happened to my Dahlias?
Hi All.. Need some of your expert advice :) I searched through my Ortho Problem Solver book, but I cant seem to figure out what happened to my beautiful dahlias (tears). Here's some pics of what they looked like a month ago. So full and healthy! Click the pic to see it larger.
And here's what they look like now. They are lost all their bottom leaves which turned brown,I have been removing them, hence I guess why they look so thin. I'm sprayed them several times with the Ortho Systemic Insect Spray, but I guess it never helped. What do you think the problem was/is? I'm about to remove them bc they look so pitiful. :(
