Planting method of Forsythia suspensa

1. Soil selection and land preparation

Forsythia suspensa does not have strict requirements on soil, and it can also grow normally in slightly acidic and saline-alkali soil. it is best for us to choose sandy soil with loose fertility and good drainage, preferably in the sunny or gentle slope zone, which is beneficial to its cross-pollination and improve the fruit rate.

2. Colonization

Forsythia is very important when it is planted, it is necessary to apply sufficient base fertilizer in the planting hole regularly, and it is suitable to use soil miscellaneous fertilizer and compound fertilizer. When planting, it is necessary to ensure that its root system is extended, and then cover the soil, which is higher than the surface of the hole, so that the sinking of the hole soil can be avoided. It is not conducive to plant survival and growth.

3. Loosen the soil and weed

Forsythia should often loosen the soil and weed at the seedling stage, the soil is easy to harden after watering, the air permeability is poor, and the root system is difficult to breathe, which is not conducive to the growth and development of seedlings. Weeds grab nutrients around the plant, so the plant grows too slowly, and weeds need to be weeded once a year except at the seedling stage.

4. Fertilization

Fertilization can be combined with loosening soil and weeding, the dosage standard is 2 kg per young tree and 10 kg per structural tree. Fertilization can be applied once before flowering to ensure the nutrient supply of flowering and once after pruning.

5. Irrigation, drainage and irrigation

Forsythia likes the wet environment, but avoid waterlogging, so it is necessary to keep the soil moist when planting, timely watering when dry, and timely drainage in the rainy season to avoid rotting roots.

6. Pruning

When the plant grows to 1 meter high, its top tip can be cut off and its heart can be removed in summer, which can promote its multi-branching. When there are more lateral branches, in order to ensure the exuberant growth of the plant, some lateral branches can be cut off and nutrient consumption can be reduced. Select several well-developed lateral branches and cultivate them into main branches.

According to the sowing and planting methods of Forsythia suspensa brought by the above pro-agricultural network, Forsythia suspensa has fewer diseases and insect pests, and the only thing we should pay attention to when planting is the fear of waterlogging, so we should pay attention to drainage in the rainy season. I hope it can help you.
