1, soil replacement method
The root system of lemon likes flowerpots with relatively good air permeability, so it is recommended to choose pottery pots. In addition, the soil should be changed every spring and autumn. The specific method is to pull the plants out of the pot, leaving the main roots and the remaining fine roots to be removed. The original potted soil can be replaced by weakly acidic flower soil with certain fertilizer conservation ability.
2. Water method
In order to ensure flowering and fruiting in the coming year, it is particularly important to cut off water in time; Don't water the lemon gradually from the beginning of September to the middle of September every year until the soil and leaves in the basin are dry, and then water it again, but there can be no water accumulation; This can reduce the overgrowth of potted lemon branches.
3. Pruning method
Pruning in spring and autumn rainy days is the best time; Try not to grow tall in potted plants. Tree can be rounded, thick branches can be left, weak branches and diseased branches can be cut off. This can fundamentally solve the problem that only leaves grow without fruit. Lemon potted plants should be pruned and supported in time to protect mature fruits.
4, pest control methods
The fragrant smell of lemon attracts insects easily. The best way to deal with insects is to cut more and spray more pesticides. Take scissors and cut them with leaves and insects. When the lemon is ripe, spray pesticides once every three days and once a week. Of course, don't spray it on rainy days, when it blooms and bears fruit.
How to raise potted lemon trees;
1. Generally, lemons bear fruit in two years, but those in three years can bear more. First pull out the whole lemon tree, shovel off all the fine roots except the main roots, then spread fertilizer soil and a layer of pastoral soil on the bottom of the basin, and then plant it.
2. After planting, leave it alone after autumn and let it grow. Winter is almost over, almost around beginning of spring. Try to bend some slender and stout branches, try to form an N-shape with the branches at the bottom, and be careful not to break them when bending.
3, the rest is simple, as long as you pay attention to pollination when flowering, and pay attention to fertilization as a result, it is basically no problem to protect flowers and fruits.
4. Some lemons have long leaves and don't bloom. This is also a common problem of lemons. Lemons need pruning. Pruning time is spring and autumn, and rainy days are the best. I won't let the potted plant grow tall, let it grow short and round, and try to keep thick branches. Tie the long branches in the old way, trim the branches of insect leaves as much as possible, and cut off the leaves.
