There are two methods of propagating avocados, one is seed propagation and the other is grafting propagation. Sowing is usually carried out in spring. Before sowing, the seeds are soaked in water for a day and then sealed and moisturized for germination. After germination, plant it in a loose and fertile seedbed and transplant it when it grows to 15-30 cm. For grafting, Mexican lines are often used as rootstocks, and West Indian or Guatemalan lines are used as scions, which can be used for bud grafting, cleft grafting and butt grafting.

1. Sowing and propagation

1. Sowing time: Avocado sowing time is generally in spring, when the climate is relatively warm, which is very helpful for the seeds to take root and germinate. Since it is intolerant of heat and cold, it is rarely planted in summer or winter.

2. How to germinate: Wash the avocado seeds and soak them in water for a day and night. After taking them out the next day, wrap them in wet paper towels and put them in a sealed box. Generally, the seeds will germinate after two to three weeks.

3. Sowing: Prepare loose and fertile sandy loam as a seedbed , bury the avocado seeds inside, cover them with soil, pour an appropriate amount of water, and wait for them to grow seedlings.

4. Seedling care: After planting, avocados need to be properly shaded to avoid exposure to sunlight. Pour water every morning and evening to keep the soil moist. Wait until it germinates and see the light. Transplant when it grows to 15-30 cm.

2. Grafting Reproduction

1 Rootstock selection: Mexican seedlings are usually used as rootstocks for avocado grafting. Compared with West Indian and Guatemalan varieties, Mexican varieties have stronger cold resistance, which is beneficial to the growth and overwintering of the plant.

2. Scoion selection: The scions of avocados are generally made from high-quality West Indian or Guatemalan varieties. Depending on the grafting method, there are also requirements for the age of the scion. Generally, 1 annual middle branch is selected for bud grafting, 3-4 year old seedlings are used for cleft grafting, and seedlings that are half a year old to one year old are used for butt grafting.

3. Grafting: If it is bud grafting, you need to Cut off the axillary bud, cut it into a shield shape, and insert it into the T-shaped incision of the rootstock. For cleft grafting, the bottom of the scion needs to be cut into a wedge shape, the rootstock split in the middle, and inserted into it. Regardless of the grafting method, after the grafting is completed, it needs to be tightly wrapped with plastic film to prevent moisture from entering.
