Golden orange trees are very suitable for maintenance at home during festive festivals, especially during the Spring Festival as green plants for spring flowers. What if the kumquat tree loses its leaves? How to grow potted plants? What are the precautions?

What if the kumquat tree loses its leaves?

The loss of leaves of kumquat trees is generally caused by insufficient nutrients, improper watering and insect pests. Among them, the loss of leaves is more common when there are insufficient nutrients and improper watering. These are all problems of improper maintenance. Diseases and insect pests are often caused by improper maintenance. The main reasons for the loss of kumquat leaves are as follows:

(1) lack of nutrients: Kumquat trees like to grow in slightly acidic, fertile, loose, air permeability and good drainage soil. Sometimes kumquat trees lose their leaves due to lack of nutrients. It is common to lose leaves when there is a lack of nitrogen fertilizer. During the growth of the kumquat tree, we usually need to add some acidic fertilizer to it. If the soil is hardened, we also need to loosen the soil in time or change some fertile and loose soil. Kumquat enters the dormant period in winter, we should stop fertilizing, if the application of chemical fertilizer can easily lead to root burning, root burning will also lead to the loss of leaves. Kumquat trees are not resistant to cold, and if the winter temperature is too low, it will lead to the loss of leaves.

Rescue method: don't fertilize the kumquat tree in winter. if the temperature is too low, we'd better give it some measures to keep it warm, or keep it in a place with plenty of light indoors. If there is a lack of nitrogen fertilizer, we can add some appropriately, but do not apply too much fertilizer. In addition, the growth of the golden orange tree requires the regular application of some ferrous sulfate solution to supplement iron to prevent the leaves from yellowing due to iron deficiency.

(2) improper watering: too much or too little watering will lead to the loss of leaves of kumquat trees. Like most plants, too much watering will lead to stagnant water soaking roots and poor breathing and loss of leaves. On the other hand, long-term lack of water will also lose leaves due to lack of water.

Rescue method: watering the kumquat tree according to the dry and wet method is the best way. This can ensure that the orange tree will not be short of water for a long time and will not soak its roots in water.

(3) insect damage: Golden orange trees are easy to attract insects, and the common pests are red spiders and yellow spiders. Once the golden orange tree is attacked by these insects, it will cause the loss of leaves, the first manifestation of which is yellow spots on the leaves.

Rescue method: lack of light is a common factor leading to the occurrence of insect pests, so we usually give more sunlight to kumquat trees to enhance their resistance to diseases and insect pests. After the appearance of the red spider, we should use medicine to prevent and cure it in time.

Second, how to raise the potted kumquat tree?

Pot oranges, such as improper management, often only blossom, no fruit or little fruit, or even do not blossom. In order to make potted oranges blossom and bear fruit year after year, scientific management must be carried out in water, fertilizer, pruning and other links in order to achieve the goal of abundant fruit.

1. Selection of pots: the selection of flowerpots for breeding kumquat is very important. We should try our best to choose plain roasting pots with good air permeability, so as to ensure that there is enough oxygen in the roots of small kumquat trees. In the shape of the flowerpot, we should try to choose a large volume, which is conducive to the growth of the root system.

two。 Soil selection: the soil for breeding kumquat is neutral, rich in humus nutrients and air permeability, so we can mix humus soil with sandy soil, which is very effective.

3. Watering: there is more watering of kumquat, because the growth of kumquat needs more water, we should choose morning or evening to water, and we should water more in summer to keep the soil moist and less water in winter.

4. Pruning: we should talk about the method of pruning kumquat. We can trim it into a round head shape, a triple cup shape or other shapes we like.

5. Fertilization: oranges like fertilizer, usually should apply more thin fertilizer, orange growth period, you can sprinkle some cake fertilizer in the basin, so that each watering there are some fertilizer infiltrated into the soil to enhance fertility. After entering autumn, fertilization is reduced to avoid overnutrition of plants, promote autumn shoots, and compete with fruits for nutrients, resulting in fruit drop.

6. Turn the pot: potted oranges due to the lack of potted soil, nutrition supply is very limited, after many years, the lack of soil fertility, oranges will be weak year by year, less flowering, not much fruit. In order to keep oranges blossom and bear fruit year after year, the pot must be turned. Cut off the old root at the end of the root, disinfect the new soil in the sun for 2 days in advance, mix the right amount of fertilizer, and transplant the trimmed kumquat into it.

7. Light: kumquat likes to grow in places with plenty of light. We should let kumquat bask in the sun as much as possible. If we can't provide enough sunlight to kumquat, it will blossom and bear less fruit.

Matters needing attention in the cultivation of golden orange trees

1. Appropriate fertilizer

After each pruning, the kumquat tree should apply mature organic fertilizer, such as human and livestock manure, plant fertilizer, preferably every ten days, and keep the temperature up to the standard and plenty of water. Only in this way can it contribute to the normal growth of the kumquat tree. If its fruit is removed, quick-acting phosphate fertilizer should be applied to promote its flower bud growth.

two。 Watering method

When the kumquat tree is in the flower bud differentiation period, it is necessary to reduce the amount of water and wait until there is a withering phenomenon on the new buds, so that it can control its excessive plant, and the resulting lack of nutrition can also promote the differentiation of flower buds. In addition, large amounts of water can not be watered during flowering and fruit-setting period, and it must be watered normally after stabilizing the fruit.

3. Pruning method

In order to make the kumquat tree more beautiful and fruitful, it should be pruned every year before the sap flows, cutting off its withered branches, branches of disease and insect pests, and branches with dense leaves, leaving only 3 to 4 strong and evenly distributed branches, and 2 to 3 new buds on each branch.

4. Reproduction method

The propagation method of kumquat tree can use grafting, including bud grafting and grafting, branch grafting, if it is rootstock, it is necessary to use seedlings of medlar, lime and so on, and cutting method can be used from March to April in spring, bud grafting method can be used from June to September, but general kumquat trees will rely on grafting method, from April to July.
