How do potted lemon trees grow well? How many years does it usually take to get a result?

Lemon tree is a kind of fruit with extremely sour taste, which is generally used to make seasoning, cosmetics, medicine and so on. Lemon trees are common in the south of the Yangtze River in China, and the requirement for planting temperature is relatively high. Let's take a look at how potted lemon trees grow well. How many years does it usually take to get a result?

First, how can potted lemon trees grow well?

1. Light and temperature

Lemon is a light-loving plant, but if the sun is too strong, it will grow poorly. Generally, at noon, the annual average temperature for plant replacement is more than 15 ℃, and the optimum growth temperature is 23 ℃ to 29 ℃. If the plant stops growing at more than 35 ℃, it will be damaged by freezing at-2 ℃. Lemons generally do not need to cool down in summer, enter the room before Frosts Descent and leave the room after Qingming Festival, which can survive the winter safely. Potted lemons should be moved to a mild environment suitable for growth at noon in midsummer. The most suitable growth temperature is 20*C~30C. Lemon likes fertilizer, and more nitrogen fertilizer is applied during the flourishing period of branch and leaf growth in spring to promote multiple spring shoots and pick the heart in time. Some rotten cake fertilizer and water can also be applied to enhance plant fertility and promote branches to mature earlier. After entering autumn, reduce fertilization, avoid branches and leaves too luxuriant sprouting autumn shoots, compete with fruit for nutrients.

2. Rational fertilization

Lemon prefer fertilizer, in addition to the basin, change the basin to apply sufficient base fertilizer, the growth period should adhere to the principle of thin fertilizer and frequent application. The times and amount of fertilization should be determined according to the growth and phenological period. The plants were treated with rotten liquid fertilizer before sprouting, and then every 7-10 days with liquid fertilizer dominated by nitrogen fertilizer to promote the growth of branches and leaves and multiple spring shoots. After picking the heart every time, it is necessary to apply fertilizer in time to make the branches mature earlier. Lemon growth period, can sprinkle some cake fertilizer in the basin, so that each watering there are some fertilizer infiltrated into the soil to enhance fertility. After entering autumn, fertilization is reduced to avoid overnutrition of plants, promote autumn shoots, and compete with fruits for nutrients, resulting in fruit drop.

3. Watering

Lemon needs more water in its growth and development, but it is not easy to rot its roots if it has too much water. Potted lemons can be placed in a sheltered environment to keep the pot soil moist. In addition to the lemon flowering time less watering, in the lemon vegetative growth period, fruiting period and expansion period should be determined according to the weak growth of lemon. Watering should not be too little or too much. Both drought and stagnant water can make lemons fall fruit. The summer light is strong, the temperature is high, needs more water. However, it should be timely and appropriate, otherwise it will cause fruit drop. Autumn is the period of shoot growth and rapid fruit expansion, so there must be sufficient water. Late autumn and winter are the period of flower bud differentiation, while the basin soil is dry.

4. Pruning

If you want more lemons to blossom and bear fruit, timely pruning is indispensable. Before spring shoot germination, cut off disease and insect branches, cross branches, introverted branches and newly sprouting branches, leave 4 or 5 full buds for strong branches, and 2 or 3 buds for weak branches, so as to promote more robust spring shoots on each branch. After the spring shoot has grown, the 3 or 4 nodes of the shoot can be cut off in order to control its overgrowth. In the future, the new shoots will be plucked when there are 6-8 knots to promote more summer shoots.

5. Turn the basin

Potted lemon due to the lack of potted soil, nutrition supply is very limited, after many years, the lack of soil fertility, lemon will be weak year by year, less blossom, less fruit. In order to keep the lemon blossom and bear fruit year after year, the pot must be turned. The best time to turn the basin is half a month before the lemon sprouts.

6. Diseases and insect pests

Lemon has strong disease resistance, especially in the north, potted plants have few diseases and insect pests, so you can prepare some insecticidal and acaricidal agents as prevention.

Second, how many years does it take for lemon trees to bear fruit?

Lemon began to bear fruit in the 3rd year after planting and reached commercial fruit after 5 years. The florescence is from April to May and the fruiting period is from September to November. Potted lemons, such as improper management, often only blossom, no fruit or little fruit, or even do not blossom. In order to make potted lemon blossom and bear fruit year after year, scientific management must be carried out in water, fertilizer, pruning and other links in order to achieve the goal of abundant fruit.
