The width of the border should be considered to be able to build a greenhouse and cover the sunshade net. Generally, the width of the border is 0.5m in one row and 0.6m to 0.8m in double row. Aloe propagation method: 1, seed sowing method seed sowing in spring, need sand plate to raise seedlings, and then transplant. 2. The method of dividing plants is combined with changing pots in early spring, and the new tillers around the mother plant are cut off from the underground stem of the mother plant, and are cultivated as seed plants. However, this method has a small number of tillers and less reproduction. 3. Cuttings are usually propagated by cuttings. The method is to cut the small lateral branches between the base of the main stem and leaf axils between spring and summer for cutting. Cut the new buds of 10~15cm, cut them from the base with a knife and place them in the shade for 1 day. After the cut is slightly dry, it is inserted into the culture soil. It can not be watered until 3 cm deep for 1 week, and it can take root in about 20 ~ 30 days. The trunk can also be cut off. Spring is the best time for cuttings to survive the winter safely.

Aloe harvesting method: leaves can be harvested from bottom to top in stages after the plant has grown up. The parts that can be harvested are tiller buds, leaves, flowers, scape and roots. Harvesting tiller buds can be used for reproduction. Aloe vera used for harvesting leaves must be more than 3 years old, each plant must have more than 20 leaves, most leaves must have 500g weight, 3 leaves can be harvested every time, 3 leaves can be harvested 4 times a year, and the mother plant must have more than 12 leaves and cannot be overharvested.
