As with other plants, the right location is initially of crucial importance for care. Coming from the subtropics, where the sun shines all year round and is warm and humid, the lemon tree needs a lot of light. If you want the lemon tree as a houseplant, you have to organize a bright location for it. The tree will feel right at home by a large, south-facing window. The lack of light can be problematic for the plant, especially in winter. The leaves are pale and the tree often sheds them when it doesn’t get enough light. In summer you can put the lemon tree on the terrace. The sun’s rays will have a positive effect on flower formation and the growth of the plant.

Tap water should first stand for a few days so that the limescale settles on the ground. As soon as the water flows out of the holes at the bottom of the pot, you don’t need to pour any more. Remove excess water regularly. Fertilize the citrus tree every two to three weeks with a nitrogenous liquid fertilizer that is low in phosphorus. In winter the plant is not fertilized and only poured enough that the soil does not dry out completely.

The lemon plant needs to be repotted every two to three years. If the bale is completely rooted, repotting is necessary. In the new bucket there must be 2-3 cm of space between the root ball and the edge of the pot. The new planter should be about a third larger than the root ball of the lemon tree. Then give the plant enough time to grow because the changes in the plant world take more time, especially when the light and temperatures are not exactly summery.

A lemon tree does not need pruning like the fruit trees, for example. You should cut a lemon tree if you want to give the crown a certain shape. In order for the leaves inside the crown to be supplied with sufficient light, it should become lighter towards the inside. The cut stimulates the growth of the tree and the branching of the branches. Remove damaged or dead branches. Branches that are too thin can also be cut out because they cannot bear fruit. Cross-growing branches can also be cut off. Use sharp and clean scissors and try to always make the cut perpendicular. Otherwise, water could collect on the cut surface. You can prune a lemon tree either before the flowering period or after the main flowering and harvesting period.

After its winter quarters, the lemon tree has to be gradually accustomed to the sun again.
