How is rose grafted
Grafting is one of the important methods for rose reproduction. Through grafting, excellent varieties of rose branches can be grafted onto strong rootstocks, thereby improving the disease resistance and growth ability of roses. The following are detailed steps and precautions for rose grafting.
1. Preparation work before grafting
Before grafting roses, the following tools and materials need to be prepared:
| Tools/materials | use |
|---|---|
| Sharp grafting knife | Used to cut rootstocks and spikes |
| Rootstock (such as wild rose) | As the basis for grafting, providing root system and resistance |
| Scion (Excellent rose variety) | Branches used for grafting must be healthy and disease-free |
| Grafted film or plastic tape | Fix scion and rootstock to prevent water loss |
| Disinfectant (such as alcohol) | Disinfection tools to prevent infection |
2. Grafting steps
1.Select rootstock and spike: The rootstock should be selected for wild roses that grow strongly and are free of diseases and pests or other suitable rose rootstocks. The scion should be semi-lignified and branches with 2-3 bud eyes.
2.Cut rootwood: Use a grafting knife to cut a "T" incision on the smooth part of the rootstock, and the depth is appropriate to just cut the bark.
3.Treatment of scion: Cut the lower end of the scion into a wedge shape, and the length matches the incision of the rootstock.
4.Insert scion: Insert the scion into the "T"-shaped incision of the rootstock to ensure the formation of layers is aligned.
5.Binding and fixing: Use a grafted film or plastic tape to tie the scion and rootstock to ensure that the scion and rootstock are closely connected.
6.Post-management: After grafting, the soil should be kept moist and avoid direct sunlight. After the scion germinates, the light should be gradually increased.
3. Things to note after grafting
| Things to note | illustrate |
|---|---|
| Avoid excessive watering | Too much moisture can cause scion rot |
| Prevent pests and diseases | Regular inspections and timely handling pests and diseases |
| Unbind at the right time | After scion survives, you need to untie the latches to avoid injury |
| Rational fertilization | After grafting, a small amount of thin fertilizer can be applied to promote growth |
4. Common problems and solutions for grafting
1.Scouts do not sprout: It may be that the formation layer is not aligned or is tied too tightly and needs to be regrafted.
2.Scion wither: It may be due to insufficient moisture or infection with bacteria, and watering and disinfection are required.
3.Rootstock sprouts: The buds of the rootstock should be erased in time to avoid nutrient consumption.
5. The best time for grafting
The best time for rose grafting is spring (March-April) or autumn (September-October). At this time, the temperature is suitable, the rootstock and scion are more active, and the grafting success rate is higher.
6. Summary
The grafting of roses is a highly technical job that requires patience and care. By selecting the appropriate rootstock and scion, mastering the correct grafting method, and doing a good job in post-management, the success rate of grafting can be greatly improved and healthy and beautiful roses can be cultivated.
