5. Flowering
When your plants start to grow you may notice that some of the flowers that come up on the leaves will drop off of the plant and fail to produce any fruit. However, the flowers that remain will each yield a fruit.
The flowers of eggplant are self-pollinating. This means that they do not need any insects in order for pollination to happen. If you end up with a poor set of fruit, hand-pollinating the flowers can help to improve production.
You can use an electric toothbrush in order to vibrate the stems of the flowers. Do not use it on the actual flowers as this can cause damage. Vibrating the stems of the flowers will help to move the pollen within each of the flowers and should increase growth and production.
In addition, it is important to make sure that you harvest the fruits on a regular basis.
