The reason why lemon trees only bloom but do not bear fruit

The reason why flowers bloom but no fruits

Water before flowers

To prevent excessive growth of summer shoots and to allow the tree to accumulate nutrients and promote the formation of flower buds, the potted lemons should be "reduced from water" before the beginning of autumn (around August 23). The specific method is to gradually reduce the water supply to the potted lemons more than ten days before the Beginning of Autumn; stop watering for the first 5 days. The potting soil is exposed to the sun, a large amount of water evaporates, and the potting soil becomes dry; the roots lack water, resulting in water loss in the branches and leaves, and the leaves become shriveled and curled. To prevent the leaves from dehydrating, you can spray water on the leaves in the morning and evening. You can also spray a small amount of water on the soil in the pot to keep the lemon in a condition that is both dry but not dead. Instead, its axillary buds will grow larger and the color of the buds will turn from green to white. When most of the axillary buds turn from green to white, the "withholding water" to promote flowering will be successful. At this time, it is necessary to resume water supply to the potted lemon in time.

Preserve flowers and fruits

After the lemon blooms, in addition to applying a thin layer of fertilizer once a week, it is also necessary to thin out the flowers and fruits. Before the flowers bloom, some of the flower buds should be thinned out; after the flowers have faded and the fruits have set, some young fruits that are out of place should be thinned out. The purpose is to reduce the consumption of nutrients and concentrate the limited nutrients on the remaining flowers and fruits, so that the fruits can grow bigger and better. During the fruit growth period, if there is sufficient fertilizer and water and the nutritional condition of the plant is good, some branches will sprout new shoots. The growth of new shoots will inevitably divert some nutrients and affect the growth of the fruit. To preserve the fruit, new shoots should be removed in time. When the fruits turn yellow and ripe, stop fertilizing and reduce watering, keeping the soil moist but slightly dry. If you continue to apply too much fertilizer and water, the fruits will mature and fall early, shortening the viewing time.

Reasonable fertilization

Lemon likes fertilizer, so you should apply thin fertilizer more often. Apply decomposed liquid fertilizer once before the plant sprouts, and then apply liquid fertilizer mainly composed of nitrogen once every 7 to 10 days to promote the growth of more branches and leaves and spring shoots. After each pinching, fertilize in time to promote early aging of the branches. During the growth period of lemon, you can sprinkle some cake fertilizer on the surface of the pot so that some fertilizer can seep into the soil every time you water it, thus enhancing its fertility. After autumn, reduce the application of fertilizer to avoid overnutrition of the plants, which will promote the growth of autumn shoots and compete with the fruits for nutrients and cause fruit drop.
