why non-stops flowers lack bushy centers
I have the same thing happen most years: non-stop begonias that are supposed to be camellia type flowers with bushy center always single out.
first I thought it's not enough ferts. I am feeding them with African violet ferts 7-7-7 and then 8-14-9 with every feed alternating.
they were still not full.
when it got very hot I took them indoors for a few weeks, they seemed to like it and leaves got better.
now the nights dropped to mid-low 60s, days in low 80s - they are out again and doing good. finally some of them produced 'camellia' flowers, but only one or two per plant.
I have 2 picotees with mostly poorly formed flowers, but some are coming out good.
any suggestions on how to improve the flowers?
