Can't get blooms
I grow a lot of tropical plant outside in summer (full sun) and winter them under a high intensity light in my basement. Some have not bloomed since the first year I got them (Podranea) some very late in the summer (Duranta, Brugmansia - no buds yet), some have never bloomed ((Solanum rantonnetti, Mirabilis longiflora). This year I cut back on fertilizer - 1/4 tsp 20-20-20 per gallon of water alternating with plain water. No difference. Some other things bloom extravagantly. All are somewhat pot-bound. Any ideas?
