How to Manage Citrus in June
Providing netizens with answers on how to manage citrus in June and understanding the methods for citrus maintenance in June, here are some green plant care tips and related details:
Citrus refers to the general name for fruit trees such as oranges, tangerines, grapefruits, and pomelos. At the beginning of June, citrus fruit trees have just finished flowering and are at the peak of the physiological fruit drop period. By the end of June, after the fruit has stabilized, they enter the fruit expansion stage. Moreover, June has a hot climate and abundant rainfall, which can easily lead to diseases and pests. Therefore, June is a period of very challenging management for citrus fruit trees. The key is to control the summer shoots, ensure fruit stability, prevent fruit cracking and sunscald, manage water properly, and control diseases and pests. Here is an introduction on how to manage citrus in June.
I. Fertilization Management
1. Control the amount of nitrogen fertilizer
In June, it is important to control growth. With frequent rainfall in June and weak sunlight, the amount of nitrogen fertilizer should be controlled to prevent excessive tree shoot growth.
2. Improve tree vigor
For trees with fewer fruits, it is necessary to increase fertilizers rich in phosphorus and potassium elements, as well as medium and trace nutrients.
3. Protect and strengthen the fruit
From May to July, citrus trees grow summer shoots, which can increase physiological fruit drop. Therefore, fertilizing the trees in June is necessary to protect the fruit. Root or foliar application of phosphorus and potassium fertilizers can help the summer shoots mature and form flower buds the following year. Trees with excessive fruit drop should be sprayed with flower and fruit expert + Shierkang + brassinolide.
4. Prevent sunscald and fruit cracking
It is possible to spray 1 or 2 times with brassinolide + boron fertilizer + ultra-high phosphorus potassium foliar fertilizer.
5. Stabilize the fruit
For strong trees with many fruits, it is appropriate to apply a balanced nutrient fertilizer and spray foliar fertilizer to help stabilize the fruit and enhance tree vigor.
II. Disease and Pest Control
1. Pest control measures
In June, it is necessary to prevent and control pests such as red spiders, leaf miners, oblique-striped caterpillars, and billbug beetles. April to June is the peak period for red spiders, and they can be killed with emamectin benzoate, etoxazole, or spirodiclofen. Leaf miners start to appear at the end of May and can be controlled with abamectin, flonicamid, and imidacloprid. The nymph hatching period for most scale insects is from mid-May to early June, and control measures must be taken before mid-June. Spraying should be uniform and thorough, avoiding rainy days. Bacillus thuringiensis can be used to kill the larvae of oblique-striped caterpillars.
2. Disease control measures
In June, diseases such as anthracnose, black spot, and greasy spot can also occur. When diseases appear, it is necessary to clean the garden and spray pesticides for control.
III. Water Management
With heavy rainfall in June, it is important to dig drainage ditches in the orchard to manage waterlogging. For orchards affected by flooding, accumulated water should be removed promptly, and leaves should be cleaned and foliar fertilizers applied. If there is prolonged high temperatures and little rain, watering should be done in a timely manner. After a long drought, it is important to water in small and frequent amounts to prevent fruit cracking.
IV. Management of Young Trees
Young trees need to be defoliated and thinned at the beginning of June, removing dense and diseased branches, shortening the central trunk and main branches, and applying appropriate fertilization to promote the maturation of summer shoots.
The above is a detailed explanation of how to manage citrus in June and understand the management methods for citrus in June. I hope this information is helpful to you!
