I think its still a tad to early. Ive have lots of blooms on my hot
peppers, but they were started very early, and had been
growing in the
greenhouse. Maybe the weather has been too warm as well.
peppers tend to need warm days and cool nights to set flowering (ideal is 70's during day- 50's at night). Too much heat and they can drop there blooms or not set any. Bloom booster (high phosphate fertilizers) do work, but I would use it after the plant gets bulked up. I tend to use fertilzers thats a little higher in Nitrogen earlier in the season, until the plants estabilish in size, then switch over to high phosphate. Also a note on the bacterial leaf spots- alot of times that can be born from your
seeds! Some people make a mild bleach solution to treat there
seeds, before they plant/germinate there
seeds.You may want to try another brand of
seeds next season. Also practice some garden sanitation at the end of the season- get rid of your old dead
pepper plants, and fallen fruits- dont mulch/turn them under.
