How to improve the survival rate of rose grafting

Material factors of rose grafting

Choosing the right rootstock

The rootstock is very important for plant grafting propagation. The rootstock is an important part that supports plant growth and nutrient transport. The quality of the rootstock affects the grafting survival rate of roses, so when grafting, you should choose a suitable rootstock.

The rootstocks used for rose grafting are mostly rose and its variants. These rootstocks have well-developed root systems and a certain affinity, which facilitates the survival of the graft.

Choosing the right scion

The selection of scion is very important because it is directly related to whether the scion will survive.

Normally, scions are usually chosen from one-year-old branches that have bloomed. They are required to be strong and free of diseases and pests, and the buds on the scion should be as full as possible. Generally, the buds in the middle of the branches are the most suitable for grafting and have a higher survival rate.

Fusibility of rootstock and scion

The rootstock and scion have a large area of ​​close contact in the cambium, making grafting easier.

In fact, when grafting roses, the cambium of the rootstock and the scion cannot be completely matched. At this time, the main thing is to maximize the contact area.

Other factors in rose grafting

Climate conditions

Temperature, moisture and other conditions are important factors affecting the survival rate of rose grafting.

Basically, most rose varieties can grow rapidly within the range of 13℃-32℃, so when choosing the grafting time, you need to base it on changes in climate temperature. It is generally better to graft in winter.

Disinfection before grafting

When grafting, some tools will be used, such as knives. They should be disinfected before grafting to avoid infection by bacteria, which can reduce the death of grafted plants and increase the survival rate of grafting.

Scion treatment

When grafting roses, it is okay to directly remove the scion for grafting, but the survival rate of the grafting will increase if it is stored. The scion can be refrigerated in summer and stored in sand in winter. The storage time should not be too long and requires proper heat preservation and moisturizing.
