How to Grow a Kumquat Tree: Detailed Planting Methods and Precautions

Everyone is surely very familiar with the kumquat, a fruit that can be both eaten and enjoyed as an ornamental plant. Every golden autumn, the branches are laden with bright golden fruit, giving it very high ornamental value. Whether outdoors or indoors, growing a kumquat is a very good choice. So what exactly are the planting methods for this fruit tree?

How to Grow a Kumquat Tree

1. Planting the sapling: When planting a citrus sapling, moderately prune the root system, then place the sapling in the center of the planting hole, spread out the roots, hold it upright, and while filling in soil, gently lift the sapling upward and firm the soil. Water thoroughly to settle the roots, make a 1 m tree basin around the sapling, and cover it with rice husks. After planting the citrus sapling, carry out deep digging and hole expansion to mature the soil, prohibit planting tall-stemmed plants such as corn and wheat in the orchard, and do a good job of rational intercropping and hoeing and weeding in the orchard.

2. Fertilizer and water management: Orange trees should fully meet the needs of blood oranges for various nutrient elements. It is advocated to apply more organic fertilizer, rationally apply inorganic fertilizer and formula fertilizer, and guide fertilization according to leaf analysis results, orchard soil analysis results, blood orange phenological periods, etc. Soil fertilization is the main method, combined with foliar fertilization. Methods such as ring trench application, strip trench application, hole application and spreading fertilizer on the soil surface are used. Irrigate when the soil is dry, and drain when there is standing water.

3. Rational fertilization: Orange trees should be fertilized frequently and lightly, mainly with nitrogen fertilizer, combined with phosphorus and potassium fertilizer, fertilizing 5-6 times during the spring, summer and autumn shoot emergence periods. For mature trees, apply four good rounds of fertilizer, namely sprouting fertilizer, fruit-preserving fertilizer, fruit-strengthening fertilizer and post-harvest fertilizer. Sprouting fertilizer: 2-3 jin of chemical fertilizer and one bucket of manure water; fruit-preserving fertilizer: 1-2 jin of phosphorus and potassium fertilizer and 1 jin of chemical fertilizer; fruit-strengthening fertilizer: 1-2 jin of chemical fertilizer and 2 jin of phosphorus and potassium fertilizer; post-harvest fertilizer: 50-100 jin of organic fertilizer and 2 jin of chemical fertilizer per tree.

4. Pruning techniques: In the young tree stage, after selecting the central leader extension branch and the extension branches of each main branch and sub-main branch, carry out moderate or even heavy heading back, and use the degree of heading back and the direction of the pruning cut bud to regulate the growth balance among the main branches. In the fruiting stage, continue to choose heading back treatment for the extension branches at all levels of the framework, remove summer shoots, and promote the growth of robust autumn shoots. In autumn, use measures such as ring cutting, root pruning and water control on vigorously growing trees to promote flowering.

Kumquat Tree Planting Methods and Precautions

I. Cultivation methods

1. Soil

It likes relatively fertile and loose soil, preferably sandy and acidic. If making it into a potted plant, you can use rotted leaves plus sandy soil and add a little fertilizer, and then it is ready to use.

2. Temperature and humidity

The temperature range it needs is between 22-28°C. If the room temperature is too high, it cannot fully enter dormancy, and its growth will be poor the next year, making it prone to dropping flowers. In winter, as long as the room temperature does not get low enough to freeze water, there will be no adverse effect on its growth. Although it likes humidity, it fears waterlogging. If the soil in the pot is too moist, its roots are very likely to rot, so during its growth period the soil only needs to be appropriately moist.

3. Light

It likes areas with relatively long sunshine duration, warmth and water. When caring for it, place it in a suitable area. If there is not enough light and the atmosphere is too shady, it will grow rampant branches and leaves, and produce very few flowers and fruits. Because it likes coolness in summer, if the summer sun is too strong, it still needs to be shaded.

4. Fertilization

It likes fertilizer very much. From when its buds begin to sprout until it produces flowers, you can add fermented fertilizer water once a week. When summer comes, add more phosphorus fertilizer to promote it to grow flower buds and bear fruit. On rainy days, promptly pour out the water in the pot, otherwise the roots will rot.

II. Precautions

1. In spring, the weather is relatively dry and windy, so it is necessary to sprinkle some water on its leaves every day to help increase humidity. In summer, spray water on it two or three times a day. If it is in the flowering period, pause spraying water, otherwise the flowers will rot and fewer fruits will be produced.

2. In order for it to produce more fruit, pruning it is necessary. Before its buds grow large, give it one heavy pruning, remove the withered branches and leaves on the tree, and keep only three or four robust branches. Each branch only needs to keep two or three buds near the base, and all the rest are cut off.

How to Fertilize Kumquat

1. Apply more winter fertilizer. After picking its fruit, loosen the soil and carry out deep plowing, and apply some organic fertilizer to help it recover its growth momentum and allow its flower buds to differentiate better. In November to December, using the outer edge of the tree canopy as the standard, dig a deep trench and put in mixed fertilizer. In winter, apply more fertilizer to it. This can lay the foundation for bearing more fruit the next year. At the same time, winter fertilization should also be done early, mainly using organic fertilizer.

2. Apply spring fertilizer early. When it sprouts in spring, for example from late February to late March, apply more fertilizer to it. This can make the top of the tree grow thicker and stronger, and help the flowering branches become more robust. It can provide enough nutrients to the treetops to prepare for fruiting.

3. Apply fruit fertilizer skillfully. In mid-to-late May, N fertilizer can be used to supplement the nutrients consumed during flowering, so that the fruit will not drop due to lack of nutrients. By July to September, when the fruit has grown larger, nitrogen fertilizer combined with phosphorus and potassium fertilizer is needed, which can provide sufficient nutrients to both the fruit and the autumn shoots.

Key Care Points for Potted Kumquat

1. Soil

When potting a kumquat, choose relatively loose soil, and soil that tends to be acidic is most suitable. Before planting, appropriately put some fertilizer at the bottom of the pot soil to provide for its early growth needs. For the soil, use leaf mold combined with cake fertilizer.

2. Watering

Kumquat relatively likes a humid environment, but when watering, avoid water accumulating in the pot, otherwise it easily causes root rot.

3. Light

Kumquat growth relatively likes sunlight. When managing it, you can place it on a balcony or similar place, so that the situation of fewer flowers and fewer fruits due to insufficient light will not occur.

4. Fertilization

Fertilizing potted kumquat is a very key factor. When fertilizing, we must control the use of water and fertilizer well. After the kumquat's branches have fully grown, apply phosphorus fertilizer once, which can increase the number of flower buds and make the kumquat bear more fruit.

Kumquat likes a warm and humid growing environment, and its adaptability to the environment is also very strong, so growing a kumquat tree is not considered very difficult. For this kind of plant that can both be ornamental and edible, why not grow a pot of it at home?
