1. Soil: lemon is suitable to grow in acid soil with good permeability and drainage. A certain amount of rotten leaf soil can be added to the garden soil to increase the nutrients of the basin soil. The basin bottom can also be paved with river sand to strengthen the drainage function. Every April or so, we need to change the soil. When we change the soil, we can add some cake fertilizer as the base fertilizer.
2. Light: Lemon grows in the subtropical zone, so it needs sufficient light and warm climate. In addition to proper shade in summer, other time can see light for a long time, which can not only help its photosynthesis, but also improve its temperature
3. Watering: Lemon needs more water in the fruiting period. Especially when spring shoots are pumped, watering must be done in time to avoid soil drought. When the fruit is still small, keep the pot soil moist and let it have sufficient water absorption.
4. Fertilization: lemon can be fertilized 3-4 times a year. Apply a spring fertilizer in February to march to help it grow healthily and promote flowering. Urea was applied once after anthesis to promote the growth of fruit. After that, a compound fertilizer was applied in autumn to help the fruit expand. Apply an organic fertilizer after picking fruit so that it can recover quickly.
1. Sowing: lemon is often seeded. Select a robust fruit tree, harvest the fruit when it is mature, lay it for a few days, and then dig for seeds, or wait until spring. After taking seed, it should be sown immediately. It is not easy to germinate after losing water.
2. Grafting: grafting is also suitable for the propagation of lemon trees, with a high survival rate. Generally, it is carried out in spring and autumn. The scion is made in spring or autumn and inserted into the cutting of rootstock. Then tie it with tape, water it and wait for it to germinate.
1. Diseases: common diseases include anthrax, macular disease, etc. it is necessary to strengthen the management of water and fertilizer, pay attention to ventilation, remove the diseased branches and leaves, and control them with drugs.
2. Insect damage: there are many scale insects and whiteflies, which can be wiped out with wet cloth and sprayed with pesticide.
