What are the cultivation methods and precautions for oranges?

Orange cultivation method

Orange belongs to the Rutaceae family. The methods of reproduction include sowing, cutting, and grafting. Common cultivated varieties include Ganxia, ​​Kumquat, Bergamot, and Shatang orange.

Oranges have a certain degree of shade tolerance and prefer a warm and humid climate. They are not cold-resistant. If the temperature in winter is below minus 8 degrees, they will suffer frost damage. They are not high-temperature resistant, and the temperature cannot be higher than 37 degrees, which will affect the quality of the fruit. They are suitable for growing in deep, fertile, well-drained, neutral to slightly acidic sandy loam.

Watering method

Orange trees like a humid environment. The soil in the pot should be kept moist during the growth period, but no water accumulation should occur. Water evaporates quickly in summer. In addition to watering the pot, you should also spray water on the ground. Water less in winter.

Fertilization method

Orange trees are not very demanding on fertilizers, and soil fertilization is the main method. When planting, you can use ring ditch application, strip ditch application, hole application, and soil surface spreading, combined with foliar fertilization.

Pruning methods

Young orange trees can be lightly pruned, and overgrown branches can be cut short, dense branches and leaves can be thinned out, and inner branches should generally be retained. In the initial fruiting period, the extended branches of the main trunk should be cut short, and the summer shoots should be removed. In the peak fruiting period, the fruiting branches should be promptly cut back, and branches that block light, dead branches, and diseased and insect-infested branches should be cut off.

Orange cultivation precautions

When planting oranges, you can apply base fertilizer. During the growth period, you can apply decomposed organic liquid fertilizer once a month. Apply 0.2% potassium dihydrogen phosphate once every 40 days. The pot needs to be changed every 1-2 years. Remove the general soil and trim the dense roots. In addition, it often has pests such as red spider mites, scale insects, aphids, etc., which can be controlled with DDT emulsion spray.
