Culture method of potted kumquat

Kumquat, also known as golden jujube, kumquat, small orange, etc., is an evergreen shrub of kumquat in Rutaceae. Potted kumquat has luxuriant branches and evergreen seasons, and it is fragrant when it blossoms, the white flowers are very soft, and the fruit is yellow and red when it is ripe. Whether it is ornamental leaves, flowers and fruits, it is also very common at home. Let's take a look at the cultivation methods of potted kumquat.

Grafting propagation

Potted kumquat is usually propagated by grafting, rootstocks are grafted with Chinese wolfberry, lime or sown seedlings, grafting methods are branch grafting, bud grafting and leaning grafting, branch grafting is carried out from March to April in spring, bud grafting is carried out from June to September, and pot planting is usually carried out from April to July.

Soil allocation

Kumquat likes fertilizer, and cultivation requires fertile, loose, slightly acidic sandy loam with good drainage. When pot cultivation, it is appropriate to choose 4 parts of rotten leaf soil, 5 parts of sand soil and 1 part of cake fertilizer. When changing the pot, the hoof or mature cake fertilizer should be applied at the bottom of the pot as the base fertilizer.

Watering management

Kumquat likes to be moist but avoid stagnant water, and the basin soil is easy to rot when it is too wet, so it is better to keep the basin soil moderately moist during growth. Dry and windy in spring, it is necessary to spray water on the leaves once a day to increase air humidity. Spray water 2 or 3 times a day in summer, and spray water to the ground. But avoid spraying water during flowering to prevent rotten flowers and affect the fruit. The stagnant water in the basin should be dumped in time in the rainy season to avoid rotting roots. When you put it outdoors in summer, it is best to use bricks to cushion the flowerpot to facilitate drainage. Kumquat is sensitive to water from white flowering stage to young fruit stage. at this time, the pot soil is too dry, the pedicel and fruit stalk are easy to detach and fall off, excessive watering, poor water permeability of basin soil, and easy to cause flower and fruit drop. At this time, it is appropriate to keep the pot soil in a semi-moisture state that is not dry or wet.

Light management

Kumquat likes a warm and humid climate with plenty of sunshine and should be placed in a sunny place during maintenance. If the light is not enough and the environment is shaded, it will often cause branches and leaves to grow, blossom and bear fruit less. Because kumquat likes cool climate in summer, or summer sunshine intensity is large, it is better to put it slightly in the shade at this time. It is advisable to keep room temperature without icing in winter. If the room temperature is too high and the plant is not fully dormant, it will grow weak in the following year and it is easy to drop flowers and buds.

Temperature management

Kumquat likes a warm and refreshing growth temperature. When the temperature is lower than 10 degrees Celsius in late autumn, it should be moved indoors in time. In winter, the room temperature should be kept at 6 to 12 degrees Celsius. Too low temperature is easy to suffer frost damage, and too high will affect plant dormancy, which is not conducive to flowering and fruiting in the coming year.

adequate manuring

Potted kumquat requires proper management of water and fertilizer. Branches from the beginning of new bud germination to before flowering can be treated with mature shallow sauce and residue water every 7-10 days and poured alum fertilizer water several times. After the beginning of summer, it is appropriate to apply more phosphate fertilizer to facilitate bud pregnancy and fruiting. Results fertilization should be suspended at the initial stage, and liquid fertilizer could be applied once a week until the end of September when the young fruit grew to about 1 cm.

Reasonable pruning

Pruning is an important technical measure to make kumquat blossom multiply and bear fruit. In order to make the tree shape beautiful and fruitful, a re-pruning is carried out before the sap begins to flow every year, cutting off withered branches, disease and insect branches, over-dense branches and overgrown branches, retaining 3-4 first-year robust and well-distributed branches, each branch only leaves 2-3 buds at the base, and the rest can be cut off, so that more than 10 full spring branches can germinate. When the new plant grows slightly to 15-20 cm, the heart is removed to make the plant shape plump, and a quick-acting phosphate fertilizer is applied at this time to promote flower bud differentiation. When blooming, flowers should be thinned properly to save nutrients. After the young fruit is born, when the young fruit grows to about 1 cm, the fruit can be thinned, the sturdy branches leave 2-3 fruits per plant, the weak branches retain one fruit per branch, and the whole plant fruit evenly. Cut off the autumn a little in time, do not make the secondary fruit, in order to achieve the same shape and maturity, and improve the ornamental value.
