1、 Seed collection

The seeds are picked in September of autumn and cannot be sown immediately that year, because it is difficult to manage after winter. After picking the mature fruit, dry it in the air. One seed is mixed with three parts of sand, and the sand should be wet. Mix the seed sand and put it into a storage pit. The size of the pit depends on the number of seeds. It can be covered with soil above the ground

2、 Time

The collected seeds can be sown in the spring of the next year. In the south, it is generally March, and later in the north. In April, the temperature factor is mainly considered

3、 Method

1. Select a sunny sandy land with good drainage performance and fertile soil, turn the soil and sterilize it, excavate several ditches with a depth of 45 cm, keep the distance between the ditches at about 25 cm, sprinkle the seeds in the ditch soil according to the appropriate distance, and cover the soil with a thickness of about 2 cm. You can press it a little. Don't press it too hard

2. Use a watering can to supply water. The tax system is completely wet and kept wet. About half a month to 20 days, the seeds will sprout seedlings

4、 Maintenance

1. After the seedlings grow out, pay attention to the weeds in the field, clean up in time, loosen the soil and add an appropriate amount of fertilizer. 2. When the seedlings grow to five centimeters high, they are relatively stable and start thinning. Pull out the over dense seedlings and sick and weak seedlings to retain nutrients for strong seedlings. After that, when it grows to 10 cm, it can be planted once

3. Although I like the humid environment, the roots are afraid of ponding. In the rainy season, we should help drainage to avoid excessive waterlogging. When the water volume is large, we can dig several drainage ditches. The seedling stage is the period of vigorous growth. We should add fertilizer to ensure the fertile soil

4. The cultivation time of Forsythia suspensa is relatively long, and it can only be planted after two years
