When Does Diospyros cathayensis Bloom and What to Do If It Does Not Bear Fruit
Diospyros cathayensis is a flowering plant species native to China, and it is now distributed in many parts of the country. Diospyros cathayensis is a plant that many households like to grow today because it has very high ornamental value, with its main ornamental points being its flowers and fruit. However, many people encounter a situation where it does not bear fruit when growing it, so how should this be solved?
When Does Diospyros cathayensis Bloom
Diospyros cathayensis generally blooms between March and April each year. The flowers are pale yellow, shaped like bottles, and give off a fragrance that smells somewhat like orchid. Diospyros cathayensis plants are divided into male and female, and both bloom, but their blooming is different. Generally, when a male plant of Diospyros cathayensis blooms, it produces many flowers below the leaf buds, and the flowers look like small lanterns; when they open, the stamens can be seen. When a female plant blooms, there are only one or two flowers below the leaf buds, and the flowers are relatively large; the flowers look somewhat like persimmon flowers, and young fruit can be seen inside the flowers.
What to Do If Diospyros cathayensis Does Not Bear Fruit
1. Pruning. Focus on thinning branches, with light pruning as a supplement, combining bud removal and pinching. Emphasize cutting off inner-canopy branches, overlapping branches, upright branches, crossing branches, diseased and pest-damaged branches, etc. For water sprouts, do not keep them on vigorous trees; on old or weak trees or where a certain part lacks branches, they can be retained, and after they grow to a certain height they can be pinched to keep as reserve branches. From the fruit-setting stage to the young fruit enlargement stage, use pinching to control the sprouting of new shoots and avoid fruit drop caused by imbalanced vegetative growth. For the current year's fruiting branches, the buds below the fruiting node should be thinned out, and for buds above the fruit, counting from the fruiting node, leave 4 leaves and pinch.
2. Fertilization. In spring, mainly use nitrogen fertilizer. Commonly used nitrogen fertilizers include ammonium sulfate, human manure and urine, and cake fertilizer, which can promote branch growth and produce more new branches, preparing for cultivating new fruiting branches. During the flower bud differentiation period, mainly use phosphorus fertilizer to promote flower bud differentiation. From half a month before flower bud differentiation to the end of differentiation, apply phosphorus fertilizer once a week, such as potassium dihydrogen phosphate, superphosphate extract, etc. In the later stage of branch growth, mainly use potassium fertilizer. Commonly used potassium fertilizers include potassium nitrate, plant ash, etc. Combined with repotting or during the slow growth period, carry out partial soil replacement, and at the same time apply more cake fertilizer, bone meal fertilizer, hoof and horn shavings, etc.
3. Artificial pollination and flower and fruit thinning. When female flowers bloom relatively few, artificial pollination can be carried out. Placing it in an environment with male plants, with pollination by bees and butterflies, etc., it can also bear fruit normally. Few fruits on Diospyros cathayensis are often related to tree age and growth vigor. You can combine pruning to remove part of the flower buds and thin out deformed flowers, diseased and pest-damaged flowers, deformed fruits, and diseased and pest-damaged fruits. Generally, the ratio of leaves to flowers is 3:1, and the ratio of leaves to fruits is 15:1.
Why Diospyros cathayensis Does Not Bear Fruit
The main reasons potted Diospyros cathayensis does not bear fruit or bears few fruits are: it is dioecious, male plants do not bear fruit, or female flowers on female plants bear few fruits due to poor pollination; lack of fertilizer or improper fertilizer ratio; long-term placement in a shady and damp environment, causing excessive vegetative growth, or failure to control water during the flower bud differentiation period, leading to no fruit or a large amount of fruit drop after fruiting; failure to repot and change soil in time, causing serious leaching of nutrients in the pot soil, soil compaction in the pot, and nutrients being unable to meet the needs of Diospyros cathayensis for fruiting; failure to prune in time, failure to cultivate fruiting branch groups, etc.
When Does Diospyros cathayensis Bear Fruit
Diospyros cathayensis generally blooms in March, and female plants generally begin to set fruit in May. In October, the fruit turns orange-yellow, just like a pellet. Male plants generally do not bear fruit, and even if they do, they will not bear many fruits, but they can bear fruit through grafting. The autumn flowers of Diospyros cathayensis can also bear fruit, but the fruit is smaller than that of Diospyros cathayensis that blooms in spring.
The flowering period of Diospyros cathayensis is in early spring every year, so friends who like it should not miss it. If Diospyros cathayensis does not bear fruit during cultivation, you can start by addressing fertilization, pollination, pruning, and other aspects, strengthen care, and believe that its fruit-setting rate will definitely increase.
