Tomatoes are typically pollinated by wind or the vibrations of the wings of bees that land on their flowers. Indoor pollination needs to be done by hand. Some indoor gardeners use bumblebees or a pollinator to pollinate their tomatoes. However, these solutions are costly and best suited to a greenhouse. An electric toothbrush works well for the indoor gardener that has just a few tomato plants to pollinate. The pollen of each flower pollinates the same flower when pollen is loosened from the anther to the stigma. Poor pollination can affect the size, shape and set of tomatoes.
Select an electric toothbrush that has soft bristles on the brush. This will help to prevent damage to your tomato plants.
Pick a sunny day when the humidity is at around 70 percent to begin pollinating your tomato plants. The humidity is important during pollination. If the humidity is too high the pollen will not release from the stamen of the flowers.
Begin pollination by selecting a cluster of flowers on your tomato plant. Start between the hours of 10am and 3pm when the humidity is the lowest to get the best results. Turn on you electric toothbrush and place the bristles on the stem just below the flower cluster. There's no need to make any movements with the toothbrush because the vibration alone will loosen the pollen.
Let the toothbrush vibrate for two seconds. Place your toothbrush on the backside of the petals of individual flowers gently and only for a brief second. Do not put the brush on the face of any flowers because this can cause damage.
Continue to place your toothbrush on the stems and petals of each flower cluster. Use your electric toothbrush to pollinate your flowers every other day. Increase pollination in the winter months when sunny days are fewer to ensure pollination.
