How to propagate Forsythia suspensa

Seed propagation of Forsythia suspensa

The main method of propagation of Forsythia suspensa is seed raising. The operation steps are to collect the seeds and dry them after the fruit harvest in autumn, and then they can be sown. After germination, move it to a pot for cultivation. It should be noted that the mother plants selected should be strong, with short and thick branches, dense flowers and fruits, and free from diseases and pests. After the seeds are collected, they should be stored in sand using wet sand at a ratio of one to three. When sowing, dig shallow trenches, sow the seeds and then cover with soil. When the seedlings emerge from the soil, loosen the soil, weed and apply fertilizer in time. In addition, attention should be paid to digging ditches for drainage during the rainy season and applying thin fertilizers frequently.

Cutting propagation of Forsythia suspensa

Select excellent mother plants, cut tender branches, cut them into cuttings, soak them in rooting powder or indolebutyric acid solution and dry them in the sun, then bury the cuttings and water them. What should be noted during the cutting process is that it is suitable to be done in a semi-shaded, ventilated and cool place, especially avoiding strong light in summer. After autumn, the light should be increased appropriately to promote growth, and the room temperature should be controlled in winter. In addition, keep the environment moist and prune appropriately.

Layering propagation of Forsythia suspensa

Since Forsythia suspensa has many drooping branches, you can press the drooping branches of the mother plant into the soil in spring, carve the branches with a knife and then bury them in the soil. After that, roots and sprouts will take root at the carved areas. Wait until the second year and then you can isolate the mother plant and transplant it elsewhere.

Propagation of Forsythia suspensa by division

Because Forsythia suspensa has a well-developed root system and strong growth ability, in late autumn or early spring, dig out the root suckers around the Forsythia suspensa plants and cultivate them separately.
