Maurice, that was very informative. Frankly, I take the time to prepare the soil before I plant. It's time consuming, but, that's what I do. It is so much easier that way than to try and amend the soil around the plant. At this time I use compost/manure, peat moss, Alfalfa Meal, pellets, Milorganite, Epsom salt. I sometimes use the extended release fertilizer, fish fertilizer. After the known/proven rebloomers are done with the first set of scapes, I top dress with Alfalfa and Milorganite.
Jill, after the scape is done or close to it, I count the bud scars, pods and remaining buds.
Genesta... rebloom scape in the middle.
Genesta... scape on the right with 140 buds. The lower branch alone has 44 buds/scars.
Genesta... scape on the left with 137 buds/scars
