The roses planted take root slowly? Give it a branch and you can change it into more than one basin.

Sowing and propagation: it is mainly used to cultivate new rose varieties. It is OK to cultivate and germinate the seeds and sow them. Ramet propagation: the new root of each branch stem, which can grow into a new plant after separation. Cutting propagation: the cut branches are treated and then planted in the soil. Grafting propagation: grafting of buds or branches on other plants.

1. Sowing and reproduction

This method is mostly used to cultivate new varieties, planting the seeds collected in autumn in a bag of wet sand, then placing the bag in an environment with a large temperature difference between day and night, and then moving to a place of about 20 ℃ after a month, after the seeds germinate, they can be sown.

two。 Ramet propagation

Plant the plant deeper or cultivate soil at the roots to allow each branch to grow new roots. Then, by changing the basin, the lateral branches that grow new roots can be cut and separated into new plants.

3. Cuttage propagation

① semi-lignified branch cutting: this method is from June to September, select the branches that have just withered, cut off the stalk of the long flower, cut the lower part of the branch flat, 2-3 nodes into a small section, remove a leaf below, and then remove the withered and old leaves, and cut them with growth-stimulating hormone.

② hardwood cuttings: use the full branches of the year prepared before overwintering, the same 2-3 nodes as a small section, 10 branches as a group, tied together, dig a 30cm hole in the house with low temperature, bury the branches upside down in the soil, cover the top with the soil, while maintaining the humidity of the soil, cuttings can be carried out the following spring.

4. Grafting propagation

① bud grafting method: every 5 to 9 days, select a good bud from the healthy original plant and cut it with a knife and attach it to the white jade tang or rose rootstock. After the buds are grafted, the branches with live buds are cut, one by one, and then the branches are cut by cutting.

② grafting method: in spring, the branches can be grafted on the branches of other plants by cutting and ventral grafting.
