In June, as the temperature rises, citrus trees enter the period of summer shoot growth and rapid fruit expansion, with the second peak of root growth. Attention should be paid to preventing waterlogging and fruit drop due to high temperatures. Let's talk about the key points of managing citrus trees in June.
1. Management of Young Trees
-
Apply early summer shoot strong shoot fertilizer, and apply strong shoot fertilizer after rain. For immature summer shoots, usually use foliar top dressing to promote early maturity of summer shoots.
-
Control shoots by pinching buds. Use the "one to two or three" shoot technique to control late summer shoots. Top prune immature summer shoots to promote maturity. After summer shoots mature, select thick and strong summer shoots (generally over 30 centimeters) for short pruning to promote late summer shoots.
-
Pest and disease control. In orchards with shoots, the focus is on controlling citrus leafminer, combined with controlling swallowtail caterpillars, aphids, psyllids, and spraying to control ulcer disease and anthracnose. Spray once when late summer shoots are about 1 centimeter long.
-
Weeding and loosening soil. Remove weeds in the orchard, especially malignant weeds under the canopy. For orchards with grass planting, when weeds are too high, cut them down to cover the ground, or choose to cover with weed control fabric.
-
Field management: Surface water evaporates quickly in high temperatures. Don't forget to water the citrus orchard in time, especially newly planted small trees, which are more susceptible to wilting due to inadequate root development. Pay special attention to plots with poor water retention.
-
Also, pay attention to dredging the drainage ditches in the orchard in June, as there may be heavy rainfall. Prevent waterlogging and root rot caused by excessive stacking of the tree plate. Slightly lower the soil to ensure its permeability for the normal growth of trees.
2. Management of Fruit-Bearing Trees
-
Fruit preservation and shoot control: In June, fruit drop will continue. Fruit preservation work should not be slackened. Continue to control shoots. When it is hot and dry, pay attention to watering to keep the soil moist. For trees with a large fruit yield, thin out flower peel fruits and deformed fruits, especially trees bearing fruit for the first year.
-
Tree body management. For mature fruit-bearing trees, control summer shoot growth and shoot emergence through fertilization and watering. For trees with exposed branches such as high-grafted trees, heavily pruned trees, and old trees, they are prone to branch scorching with strong sunlight and high temperatures, and should be whitewashed. During the plum rain season, prevent waterlogging and dredge ditches and channels.
-
Pest and disease control. Beware of summer pests and diseases: citrus melanose, scab, ulcer disease, scale insects, psyllids, leafhoppers, cicadas, scale insects, flatheaded borers, citrus leafminers, red spider mites, etc. Pay attention to timely prevention and control.
-
Soil and water management: Soil management mainly includes inter-row cultivation and weeding to loosen the soil and remove weeds to promote soil microbial activity. Fertilization for fruit-bearing trees: First, apply foliar top dressing. In early June, spray foliar fertilizer on the canopy, and spray again after half a month. Second, apply root zone fertilization. In mid-to-late June, which is the period of fruit expansion, apply professional citrus fertilizer mainly, with the amount of fertilizer accounting for about 60% of the annual fertilization amount.
Calcium supplementation: Calcium deficiency in fruit-bearing trees can lead to thin fruit peel, fruit drop, and even sunburn. Citrus trees with calcium deficiency will result in short new shoots and weak plant growth. During the fruit expansion period in June, the demand for calcium is relatively large, and the calcium in the soil is far from enough to meet the needs of citrus for calcium. Calcium can be supplemented through foliar spraying to reduce fruit cracking caused by rapid fruit expansion, increase the toughness of fruit peel, and also have a certain effect on reducing sunburn fruit.
Water management: In June, it is necessary to open drainage ditches in the orchard. It is a rainy season to help the normal growth and development of trees and ensure the permeability of the soil.
Above is an introduction to the key points of managing citrus trees in June. June is an important stage for citrus from flower withering to fruit setting and preservation. Therefore, proper management in this month is essential for high citrus yields.

Frequently Asked Questions (FAQ) about Citrus Tree Management in June
Q: What should I pay attention to when managing young citrus trees in June?
A: In June, it's crucial to apply early summer shoot strong shoot fertilizer, control shoots by pinching buds, and prevent pests and diseases. Also, don't forget to weed and loosen the soil, manage field water, and ensure proper drainage.
Q: How can I protect fruit-bearing citrus trees during June?
A: For fruit-bearing trees, continue to control shoots, pay attention to fruit preservation, and manage the tree body. Be vigilant against pests and diseases, and ensure proper soil and water management, including fertilization and calcium supplementation.
Q: Why is it important to manage citrus trees in June?
A: June is a critical stage for citrus trees, transitioning from flower withering to fruit setting and preservation. Proper management during this period is essential for high citrus yields.
Q: What are some common pests and diseases affecting citrus trees in June?
A: Common pests and diseases include citrus leafminer, scab, melanose, scale insects, psyllids, leafhoppers, cicadas, flatheaded borers, and red spider mites. Timely prevention and control measures are necessary.
Q: How can I ensure proper water management for citrus trees in June?
A: In June, open drainage ditches in the orchard to help with water management, especially during the rainy season. This helps maintain normal tree growth and ensures soil permeability.
