Certain plants with male and female flowers, such as squash and cucumbers, may need a helping hand for good pollination when grown indoors or in a greenhouse. Wind and insects are not always present as in nature to achieve pollination. You can be a busy bee yourself and play the role of pollinator.
Locate the male and female flowers. Male flowers bear stamens and female ones bear pistils. The female flower has a rudimentary fruit on the end.
Transfer the pollen from the male flower to the female with a small paintbrush or cotton swab. Clean the brush or use a new swab when pollinating more than one type of plant.
Shake gently the cage of pepper and tomato plants every couple of days to advance pollination; no other action is necessary. Self-pollinators such as peas, beans and lettuce do not need any help to pollinate indoors.
