The Cultivation Method and Precautions for Kumquat
This article provides an overview of the knowledge related to the cultivation method and precautions for kumquat. The following is an introduction by the editor.
Kumquat is originally a delicious fruit with a small plant shape and is widely used for potted plant decoration, symbolizing wealth and treasure. It is also one of the commonly used potted plants for the Spring Festival decoration. Kumquat is evergreen, blooms multiple times from March to September, and the fruiting period is from October to December, with the mature period around the Spring Festival to early spring.
The Cultivation Method and Precautions for Kumquat
Kumquat is relatively easy to cultivate. If you have a courtyard, you can plant it directly in the ground in a sunny and windless place. Even without management, it can bear fruit every year, but the fruit may be smaller if not managed. For ground planting, you can apply fermented organic fertilizer once every spring and autumn to replenish fertility and simply prune the excessive branches.
For potted kumquat, due to the limited growing space, it is recommended to pay attention to the following points.
1. Pot and Potting Soil Selection
Kumquat prefers a relatively large and well-ventilated pot, such as a large ceramic pot or a single-linked planting box. The pot should not be too deep, just the conventional depth.
The potting soil should be loose, well-drained, and slightly acidic. It is recommended to mix 2 parts of garden soil, 2 parts of peat soil, and 1 part of decomposed leaf soil, or 1 part of garden soil and 1 part of nutrient-rich soil, and add fermented organic fertilizer as a base fertilizer when potting.
Kumquat trees are usually cultivated with garden soil. When repotting, if the potting soil uses the above formula containing garden soil, it can be transplanted with the original soil clump.
However, if you want to plant with pure nutrient-rich soil, it is recommended to wash the roots, remove 2/3 of the original soil clump, and then plant with nutrient-rich soil. After washing the roots, the kumquat should be placed in a diffused light area to slow down the seedlings. During this process, do not water too much, adhere to the "dry-wet" principle, and water thoroughly each time. When the plant is in good condition, gradually increase the light and enter normal fertilization and watering management.
In autumn, winter, and early spring, the survival rate of kumquat planted after washing the roots is very high, but the fruits that have already grown are likely to fall off after washing the roots.
2. Maintain Sufficient Light
Kumquat potted plants are evergreen, have a long blooming period, and a long fruiting period, requiring more light. It is usually necessary to maintain full sun or at least half-day sun. Insufficient light will reduce blooming and may even result in no fruit.
3. Fertilization and Water Management
Kumquat can bloom continuously from spring to autumn and bear many fruits. If sufficient fertilization and watering are maintained, the fruit of kumquat can grow large and sweet.
For ground planting, apply solid fermented organic fertilizer twice a year, and for potted kumquat, it is recommended to apply fermented organic fertilizer once every two months. In April and May of spring and October of autumn, you can apply bone meal fertilizer separately to promote blooming and fruiting. Outdoor cultivation can also use fermented fruit peel water or fermented fish intestine fertilizer water, and chemical water-soluble fertilizers can also be used.
For potted kumquat, it is important to water thoroughly when the top 1 cm of the soil is dry and avoid waterlogging, as it can cause flower and fruit drop. In summer, if the potting soil is too dry, you can directly soak the pot to allow the soil to absorb enough water, then follow the "dry-wet" watering method.
4. Pruning and Pest and Disease Control
The growth rate of kumquat is not very fast. Pruning can be done after the fruit harvest in spring to shape and prune the inner branches, enhancing the internal ventilation of the plant. After pruning, kumquat will sprout new branches. In summer, pay attention to shortening the excessive branches to avoid excessive growth that consumes nutrients and destroys the overall plant shape.
Kumquat rarely has pests and diseases. During maintenance, pay attention to keeping the environment ventilated. Poor ventilation may lead to red spider and sooty mold disease.
If red spiders appear, they can be treated by continuously rinsing with water or spraying red spider killer. The red spiders on kumquat are relatively easy to treat. An outdoor kumquat tree, infected with red spiders from a rose, recovered without medication and bore many fruits every year.
