I have hot pepper plants in containers, indoors. I have been having trouble with the blooms not pollinating and falling off. I have tried to use a q-tip to lightly touch the blossom, but it doesn't seem to be working. Do you have a idea to manually pollinate them. I have them under, both fluorescent, and flood grow lights; because I have limited window space. The Jalapeño pepper plant has hadgood success in the window. The Habanero is dropping blossoms in the window, along with the others
Thanks for writing. In order for pollination to be successful, you'll need to wait until the pollen is ripe (powdery) on the anthers. Using a fine paintbrush may be better because you'll be able to more easily see the pollen grains on the brush. Then transfer them to the pistil at the very center of the flower. As with most plants, you should see better pollination if you take pollen from one pepper plant onto another.
That said, it's not uncommon for peppers to drop their blossoms, even if pollinated, if they're not happy with their growing conditions. Being too warm or cool at night is the most common cause of drop. Keep your peppers over 60F at night (keep in mihdn that being right near a window it may be cooler at night than the surrounding room). And be sure not to overwater --- the potting mix should just dry between waterings (but not so much that the plants wilt).
