One of my pepper plants has started to flower, and the petals are falling off to reveal a pepper growing from that stem - well, at least the first two have, and the other flowers seem to be bulging somewhat in the middle and I assume will therefore produce fruit.
A second of my pepper plants is also flowering, but when its flowers drop off they drop off entirely, stem and all. So far three of its flowers have done this, and there's a few more flowers that don't appear to bulging like my more successful plant.
Should I be concerned about the second plant? And if so is there something I should be doing about it?
