Can lemon trees be grown indoors?

Lemon trees can be grown indoors, but if the cultivation method is incorrect, it is likely that the lemon tree will not bloom or bear fruit. Therefore, if you want to grow lemon trees, it is best to master professional growing methods and then choose the appropriate temperature for growing them, so that the lemon trees you grow can bear more fruits. Here are some things you need to pay attention to when planting lemon trees:

[Reasonable pruning]: There are two reasons for pruning potted lemon trees. First, the pot is small and the soil is small, so the nutrients provided are limited and cannot meet the growth needs of the lemon tree, so pruning is necessary. Second, through shaping and pruning, the reasonable distribution of nutrients in the tree body can be adjusted, so that the limited nutrients are concentrated on the buds and leaves, forming more fruiting branches, so that the branches are full of flowers and fruits. Potted lemon trees must be pruned intensively before the spring shoots sprout. First, remove dead branches, diseased branches, overgrown branches, inward branches, crossed branches, and sprouting branches. For strong branches, prune lightly, leaving 4.5 full buds; for weak branches, prune hard, leaving 2.3 buds, to encourage each branch to grow more strong spring shoots. After the spring shoots have grown to full height, in order to control their excessive growth, they can be lightly pruned, cutting off 3 or 4 sections of the branches. The new shoots that grow later should be pinched off when they have 6 to 8 nodes, in order to induce more summer shoots.

[Preserving flowers and fruits]: After the lemon tree blooms, in addition to applying a thin layer of fertilizer once a week, it is also necessary to thin out the flowers and fruits. Before the flowers bloom, some of the flower buds should be thinned out; after the flowers have faded and the fruits have set, some young fruits that are out of place should be thinned out. The purpose is to reduce the consumption of nutrients and concentrate the limited nutrients on the remaining flowers and fruits, so that the fruits can grow bigger and better. During the fruit growth period, if there is sufficient fertilizer and water and the nutritional condition of the plant is good, some branches will sprout new shoots. The growth of new shoots will inevitably divert some nutrients and affect the growth of the fruit. To preserve the fruit, new shoots should be removed in time. When the fruits turn yellow and ripe, stop fertilizing and reduce watering, keeping the soil moist but slightly dry. If you continue to apply too much fertilizer and water, the fruits will mature and fall early, shortening the viewing time.

[Repotting]: Potted lemon trees have very limited nutrient supply due to the small amount of soil in the pots. After many years, the soil fertility will be lacking and the lemon trees will become weaker year by year, with fewer flowers and fruits. In order to keep the lemon tree blooming and bearing fruit every year, it is necessary to repot it. The best time to repot the lemon tree is half a month before it sprouts. Before repotting, prepare a pot that is one size larger than the original one. Remove the lemon from the pot without breaking the mud ball. Scrape off 1.2 cm thick surface soil along the mud ball, cut off dead and rotten roots, and scrape off 1 cm thick soil at the bottom of the mud ball. Take out the tiles at the bottom of the original pot that are sunken into the soil. Cover the drainage holes of the new pot with tiles, first lay a 2.3 cm thick drainage layer, and then lay a 4.5 cm thick layer of nutrient-rich culture soil mixed with a small amount of superphosphate. Then put the lemon tree mud ball into the pot, fill it with culture soil around it to the mouth of the pot, compact the soil slightly, water it enough to help it take root, place it in a ventilated, semi-shaded place, and put it back to its original place after a week for daily management.
