Kumquat fruit falling at a very small age can be caused by a variety of reasons, including environmental factors during flowering and fruiting, nutritional deficiencies, pests and diseases, etc. Here are some possible causes and how to fix them:
Flowering temperature:When the temperature of kumquat is too high or too low during the flowering period, it may affect the pollen activity and lead to poor pollination. Maintaining the right temperature can help improve pollination rates. Pollen Sources:Kumquat needs an adequate pollen source, and if there are not enough other flowers or heterogeneous kumquat around, consider adding floral plants to attract pollinators such as bees.
2.Nutritional issues:
Insufficient fertilization:Deficiencies in proper nutrients, especially phosphorus, potassium and boron, can affect fruit development. Phosphorus and potassium fertilizers should be applied at the appropriate time during the fruit development period, and attention should be paid to ensuring the overall nutrient balance of the soil. Moisture Management:Kumquat needs to be properly hydrated during the growing season, and drought or over-irrigation can lead to poor fruit development. Water wisely, keep the soil moist but avoid water logging.
3.Pest and disease problems:
Fruit rot:Fruit rot may be one of the causes of early drop of kumquat fruit. To detect and control fruit rot in time, you can use pesticides to control pests and diseases, and you can also choose appropriate biological control methods. Pests:Some pests such as aphids, leaf miners, etc. may affect the development of fruits, and timely control measures should be taken, such as spraying organic pesticides.
4.Flower bud implementation issues:
Cold damage:In the flower bud differentiation stage of kumquat, sudden cold damage may lead to the implementation of flower buds, which may affect the formation of fruits. Avoid frost in spring and take thermal insulation measures in time. Heat damage:Excessively high temperatures may also cause flower bud implementation. In hot summer weather, provide appropriate shade to reduce heat stress on plants.
5.Trim Management:
Timely pruning:Proper pruning can improve the ventilation and light transmission conditions of kumquats, and promote the growth and development of plants. Timely pruning of poor, overly dense branches can help improve the quality of the fruit.
6.Maintain suitable environmental conditions:
Lighting:Kumquat needs full sunlight and good light conditions to help improve the quality and stress resistance of the fruit. Wind power:Moderate wind can help ventilate the plants, but strong winds can cause fruit to fall. To maintain a moderate amount of wind, you can use wind netting, etc.
Precautions: During the fruit expansion period and fruit ripening period, try to avoid plant movement or human interference, so as not to cause fruit loss. Inspect kumquat plants regularly to identify problems and take appropriate measures.
By taking these factors into account, kumquat plants can be better managed, fruit development rate can be improved, and early fruit drop can be reduced. If the problem persists, it is advisable to consult a local plant professional or agricultural technician for more specific guidance and assistance.
