Prospero showing extreme chlorosis on multiflora roots
I ordered Prospero from Pickering because it is one of the few nurseries offering it. I knew about the chlorosis problems on multiflora roots with Texas' alkaline soil and water so the roses received were planted very deeply in order for them to develope their own roots. All the roses are chlorotic, but poor little Prospero is the worst. Maybe it's having the hardest time growing its own roots. Even so it is valiantly trying to bloom in our up to 108 degree heat. It's planted in a super large container with a mixture of Miraclegro potting soil, peat moss, aged manure, and compost from my compost pile and deeply mulched. I probably should remove the buds, but what else can I do to help it along and try to make sure it survives? It gets about 6 or 7 hours of sun and receives plenty of water. Maybe so much sun is stressing it further, but I'd be hesitant to move it in this heat. What do you all think?
Thank goodness other than fried blooms the rest of my fifty plus roses are doing well in Texas' extreme heat and drouth.
