What causes eggplant flowers to bloom but not bear fruit?
The flowers of the eggplant tree determine the number of eggplants produced in the season, but growers often encounter a situation where the tree has a large number of flowers but bears few fruits, or even no fruit at all. So what causes this? Let's take a look below together with the editor at the reasons for this.
1. Environmental factors
Due to a lack of systematic learning, most growers in our country often overlook the effects of sunlight and temperature on flowers, and thus fail to pay attention to keeping warm, leading to a reduced number of fruits. A temperature below 15° will cause the flowers to freeze and drop, and if the temperature during the flowering period lasts less than 3 hours, the success rate of flower pollination will drop sharply, while a long rainy period will cause the flowers to be knocked down. The above are relatively common causes of flower drop, and growers should pay more attention to environmental factors.
2. Boron deficiency
Chemical fertilizers are meant to help the eggplant tree grow better, but improper application of chemical fertilizers can cause the eggplant tree to bloom without bearing fruit. The current mainstream chemical fertilizers are the three types: nitrogen, phosphorus, and potassium, but what is actually needed during flowering is the boron element. If boron is insufficient, the flowers are very likely to wither directly and will not bear fruit at all. If you usually find that the eggplant tree has batches of flowers necrosing and withering, then it may be caused by a lack of boron. Fertilizer containing boron should be added in time.
3. Pollination problems
Pollination has always been a problem that easily troubles flowers. During the growth process, some flowers will always fail to pollinate successfully for various reasons. This situation is easy to identify: if some flowers on the eggplant tree bloom very vigorously but do not bear fruit, then it is very likely a pollination problem. At this time, in order to bear fruit better, manual pollination can be chosen to increase the chance of bearing fruit.
4. Dense flowers
The last problem is relatively easy to solve. You will find that when there are too many flowers on a single eggplant tree, its flowering period will be very long, and under otherwise normal conditions it will rarely bear fruit. This is because there are too many flowers, and the nutrients of the eggplant tree are not enough to support so many flowers bearing fruit. In order for the other flowers to bear fruit, some of the weaker and smaller flowers need to be removed. You have to give up something to gain something.
The above are the problems that are relatively likely to occur when eggplant trees bloom but do not bear fruit. Sometimes several of the above situations also occur at the same time. Everyone must identify them carefully and must not apply methods mechanically. For more related information, you can come to our website.
