How to Grow a Lemon Tree: A Detailed Guide to Cultivation Methods and Precautions
Speaking of lemon trees, everyone knows that lemons have high nutritional value, so have you ever grown a lemon tree? Just like growing other fruit trees, it requires methods. Actually, growing a lemon tree should not be difficult; as long as you master the methods, you can believe that you will grow a lemon tree well. So how exactly should a lemon tree be grown? Let's take a look together with the editor.
How to Grow a Lemon Tree
1. Fertilizer and water management. Determine the timing of fertilization according to weather conditions, and decide whether to increase or decrease the amount of fertilizer based on the soil fertility and tree vigor. Irrigate promptly, and pay attention to drainage in low-lying orchards during the plum rain season.
2. Pruning and shoot control. Promptly remove summer shoots to prevent shoots from competing with fruit for nutrients, reduce the second physiological fruit drop, and prune weak branches, diseased and pest-infested branches, densely growing branches, and leggy branches to ensure ventilation and light penetration inside the tree canopy; for some old and weak trees with few fruits, moderately heavy pruning before the summer solstice and strengthened fertilizer and water management. Also promptly apply wound healing and antiseptic membrane to the cut surfaces to prevent pathogens from invading the tree body and protect wounds for healthy healing.
3. Promoting flowers and fruits. Apply the new technique of Flower Promoting King for shoot control and flower promotion, ring-bark and apply Flower Promoting King No. 2, causing the tree's growth function to transform into reproductive function, controlling shoots and promoting flowers. Before lemon flowering, during the young fruit stage, and during the fruit expansion stage, spray Fruit Strengthening and Stem Strengthening once each to increase the nutrient transport volume of the conducting vessels, enhance fruit expansion vitality, self-regulate nutrient matching, and protect flowers, protect fruits, strengthen fruits, and prevent fruit drop.
4. Pest and disease control. The main pests and diseases occurring on lemons include red and yellow spider mites, arrowhead scale, rust mites, anthracnose, and scab, etc. For control, targeted pesticides can be selected and timely control is sufficient; at the same time, spray New High Lipid Membrane to improve the utilization rate of effective ingredients in the pesticide and consolidate the control effect.
Cultivation Methods and Precautions for Lemon Trees
I. Cultivation Methods for Lemon Trees
1. Repotting and soil changing: Potted lemon trees must be repotted and have their soil changed in spring from March to April. If the flower pot is too small, replace it with a suitable pot; if the pot is still suitable, you can keep the original pot and replace it with new soil. When repotting and changing soil, apply base fertilizer.
2. Spring pruning: In spring, carry out spring pruning together with repotting, cutting off inner canopy branches, dead branches and fallen leaves, diseased and pest-infested roots and leaves, and leggy branches to facilitate fruit bearing.
3. Reasonable fertilization: Before flowering and after fruit set, lemon trees should be top-dressed multiple times, applying multi-element flower fertilizer once a month and spraying flower nutrient solution once every half month to ensure the fruit does not easily drop and is large and brightly colored.
4. Preventing leaf drop: Leaf drop affects lemon tree fruiting. To avoid leaf drop, in daily management, avoid watering that is sometimes too much and sometimes too little. Midday shading: After the lemon tree blooms and before fruit set, when the midday temperature exceeds 30 °C, it should be shaded for about 3 hours; otherwise it will affect normal flower formation and also hinder the plant from bearing fruit.
II. Precautions for Lemon Trees
To keep a lemon tree flowering and fruiting year after year, it must be repotted. The most suitable time for repotting is half a month before the lemon tree buds. Before repotting, first prepare a pot one size larger than the original pot, take the lemon out of the pot without breaking the soil ball, cut away 1.2 cm of the surface layer of old soil along the soil ball, prune dead roots and rotten roots, and cut away 1 cm of soil from the bottom of the soil ball, and remove the tile fragments originally placed at the bottom of the pot that have become buried in the soil. Place tile fragments over the drainage hole of the new pot, first spread a 2.3 cm thick drainage layer, then spread a 4.5 cm thick nutrient-rich culture soil mixed with a small amount of superphosphate. Then place the lemon tree soil ball into the pot, fill culture soil around it up to the pot rim, slightly compact the pot soil, water thoroughly to settle the roots, place it in a ventilated, semi-shaded place, and after one week put it back in its original place for routine management.
Why Does a Lemon Tree Keep Dropping Leaves?
It is definitely nutrient deficiency, or excessive fertilization. You did not wait for the surface soil to dry before watering, and you cannot water too frequently. In other words, it is too frequent. The watering did not soak through, only the surface soil was watered. This can also cause leaves to turn yellow. Also, the place where it is placed gets no sunlight. The location has no light, poor ventilation, and too much smoke. That is why the lemon tree keeps dropping leaves. The small potted lemon tree dropped leaves continuously even though it bloomed right after being bought. At first the leaves turned yellow, a few turned yellow from bottom to top and then dropped; now even green leaves gradually lose vigor and drop. They drop at the slightest touch. Watering is basically once every two days, mainly to keep the soil from becoming too dry.
Is a Potted Lemon Tree Suitable for Growing at Home?
A potted lemon tree is suitable for growing at home. In the north, move it indoors in winter and just pay attention to keeping it warm. First choose a suitable pot, and be sure to change the soil in spring and autumn. Then transplant: pull the whole lemon out, and except for the main root, cut off the other fine roots with a shovel, then lay fertilizer soil at the bottom of the pot, a layer of garden soil, and finally plant it. After planting, choose a warm environment and let it grow. When winter is almost over, around the Beginning of Spring, the time is short; at this time, friends should pay attention, because this is the time to make the lemon bloom more and bear more fruit. The method is: take some branches, whether slender or thick, it does not matter. As much as possible, be sure to bend them downward as much as possible, forming an n shape with the branches at the bottom. When bending, be careful not to break them, fix them with string, and make as many n shapes as possible on the whole lemon, which will promote nutrients to move downward, resulting in more flowers and more fruit. For pollination, as long as you pay attention to pollination when it blooms, and add fertilizer when it sets fruit, basically there will be no problem in protecting flowers and fruits.
