The crack in the container started out as a hairline when I planted it. It's growing along with the rootball.
All summer I've been using flower food that Kathy sent to me a while back--Super Bloom by GreenLight, 12-55-6. I used the last of it a few weeks ago and then started using the common-type food that's everywhere. You probably know which one I mean. A big difference. Fewer blooms, and some drooping foliage. Not good.
So I went over to see Gayle at the Apple Barn for a consult. She says I'm not feeding enough and that the plants are starving. She recommends Ferli-lome's Blooming & Rooting Food. 9-59-8. Full strength, most days. So that's the new plan. As for the crack, I'm okay with it cracking wide open as long as the blooms keep going til frost!
