Reasons for Kumquat Tree Leaf Drop and Yellowing Leaves, and How to Fix Them
The kumquat tree is not only small and lovely in appearance; at the right age and in the right season, it can also produce very delicious kumquat fruit, and it looks especially beautiful when the branches are covered with kumquats. However, growing kumquats is not all beautiful moments; once they are not grown properly, problems such as leaf drop and yellowing leaves are very likely to appear.
What to do when a kumquat tree drops its leaves
1. Not enough nutrients
If it is often kept in a low-nitrogen condition, its nutrients will be insufficient, and then its leaves will drop. During its growth period, give it more slightly acidic fertilizer and also loosen the soil for it. After it enters dormancy, in addition to strictly controlling the amount of water, you also need to stop fertilizing it, especially chemical fertilizer, otherwise it will suffer fertilizer damage and the roots will be burned. During care, the owner should make sure it gets enough nutrients and light, and then it will return to normal.
2. Improper watering
Because it prefers acidic soil, if tap water is used, it will destroy the acidity of the soil, it will lack iron, and the leaves will turn yellow and then drop. We can regularly water it with a diluted FeSO4 solution to solve this problem.
3. Pest infestation
This tree tends to attract insects, and generally red spider mites and yellow spider mites easily grow on this kind of tree. Once it is attacked by these pests, yellow spots will appear on its leaves, and if the situation is very serious, its leaves will drop. To reduce pests, give it enough light in daily care, and then there will be fewer pests.
Once signs of illness are found, use medication to control it.
Reasons for yellowing kumquat leaves and how to fix them
1. Temperature must not be lower than 8 degrees.
2. Soil should be loose and fertile. It should have a good granular structure; good soil should have granular components of a certain size. This kind of soil has large porosity, which helps drain excess water and contains enough air.
3. It is best to keep the soil moist; do not let the soil become too wet, and especially avoid waterlogging, otherwise the roots will easily rot.
4. When the soil surface turns white, water it immediately, and water thoroughly every time; never water only halfway.
5. The water temperature should be as close as possible to the soil temperature. In summer, water in the morning or evening; in winter, water at noon.
6. Rainwater is best for watering, followed by river water. If tap water is used, it should first be left to sit for several days.
What to do when kumquats drop flowers and fruit
1. Reasons kumquats drop flowers and fruit
1. Insufficient nutrients
Kumquat is an evergreen fruit tree, and its life activities continue all year round. In winter it is also producing and accumulating nutrients, carrying out flower bud differentiation, and preparing for the next year. If fertility is insufficient, it will not have the strength to form flower buds, and even if there are flower buds, it will eventually drop flowers and fruit.
2. Water imbalance
If there is a lot of rain during the flowering period, it hinders the plant's normal pollination, the flowers rot, and this can also cause flower and bud drop. Long-term drought and excessive water evaporation from the leaf surface can cause flower and fruit drop, and poor soil drainage capacity can also cause flower and bud drop.
3. Pests, diseases, and wind damage
Pests and diseases are also important reasons for kumquats dropping flowers and fruit. Once pests or diseases are found, measures should be taken promptly; if they are not found in time, even taking measures will be of no help.
2. Measures to prevent kumquats from dropping flowers and buds
Apply enough winter fertilizer before Minor Snow, apply a heavy sprouting fertilizer before the Spring Equinox, and apply appropriate additional fertilizer if growth is poor during flowering. From June—July, when the flowers fade and fruit forms, nutrients must be sufficient. From August—September, there should be enough water and abundant fertilizer.
When do kumquats bloom and bear fruit
1. After one year of planting, it can grow flowers the next year. It mainly uses the shoots that grow in spring as the mother branches for flowering and fruiting, and it can grow flowers four times throughout the year, but the fruit grown from the first flowers is the largest.
2. Its first flowering is in mid-to-late June, the second flowering is in July, the third flowering is in August, and the fourth flowering is from early September to October. From flowering to fruit ripening generally takes about 150-170 days.
Faced with all kinds of problems in the process of growing kumquats, we should be fully prepared to deal with them. By reading this article, I believe everyone has gained a certain understanding and control of the problems that may appear in kumquat cultivation, so when we encounter such problems in practice, we should all be well prepared.
