Answer: Thanks for the kind words about our book. The 16-4-2 fertilizer or something roughly equivalent, should be available through Mills Plant Food, 1-800-845-2325. Your David Austin rose may have lost it's graft union and the rootstock is now appearing. If it's in full sun, well drained soil and you still have no flowers, I'd say that's probably what happened and you should dig it out and try again.
