Which month is the best for rose grafting (the best season for rose grafting tree roses)

What is the best season for rose grafting?

Rose grafting can be done in spring and autumn every year. April to May in spring and September to October in autumn are the most suitable . The climate is warm at this time, which is more conducive to the germination and survival of the scion. As long as the soil, fertilizer and water usage are well controlled, the survival rate can be improved.

Although roses can be grafted all year round, autumn is considered the best time to graft.

Because the scion can directly enter the stage of rapid growth after grafting, the buds may not germinate after grafting in other seasons, and will only germinate in spring. Based on many years of experience, the reasons are as follows:

Although spring is the season when all things come back to life, it is also a season with a high incidence of bacteria, and the grafting site is easily infected with bacteria.

Spring is also the rainy season, so when grafting roses, the wounds formed by the rootstock and the grafted scion are easily exposed to rain, and the wounds will rot, leading to grafting failure.

The temperature in spring is unstable, and what we often call "late spring cold" is also a factor that affects the survival of grafting.

The temperature in spring has reached the right temperature for grafting, but after you have grafted, the temperature drops sharply and becomes low. Then the grafting wound cannot heal and form connecting tissue, and finally the grafted scion loses water and dries up.

Especially in the northern region, the temperature in winter and summer will form a large temperature difference, which is not suitable for the growth of roses, that is, between 15 and 30 degrees Celsius. Therefore, it can be seen that grafting in spring and autumn is most suitable.

The best season for rose grafting

Rose grafting can be done with or without roots. Those with roots are more likely to survive, while those without roots have a lower survival rate.

It is recommended to graft roses on roses in spring and autumn every year, mid-April in spring and mid-September in autumn .

Grafting is not suitable in the rainy season, and it is not suitable to graft too early in spring because the temperature is too low and the wound is difficult to heal. Grafting is not suitable to be too late in autumn because the temperature is too low and the growth is affected.

After grafting, the plant grows very fast. At this time, the grafting temperature is more conducive to wound healing, and the success rate is also the highest.

Before grafting, you must choose the right rootstock and scion to ensure that they grow strong and are free of diseases and pests. After grafting, you need to strengthen management to ensure that the grafting goes smoothly.

When is the best time to graft tree roses?

It is generally best to graft tree stump roses in winter because the roses are grafted onto the Osmanthus fragrans, which is dormant in winter and has a very high survival rate, making it suitable for grafting.

Why is autumn the best time for grafting?

When autumn comes, roses will have a small burst of growth after their summer dormancy.

The growth ability is the same as in spring, but in autumn, most pests have already laid eggs and disappeared. The dry climate reduces the growth ability of various harmful bacteria, which can reduce the occurrence of diseases and pests during grafting.

The climate is relatively dry in autumn and there are not many rainy days, so it is easy for us to protect the wounds of the grafted rootstock and scion from getting wet in the rain.

The temperature in autumn is relatively stable, and the most common thing we encounter is the "autumn tiger", which is a sudden high temperature. However, if the rose is in a shaded environment, it will not be affected even if the temperature reaches 35 degrees.

If maintained in a well-ventilated location, the autumn heat will not affect the grafting and healing of roses at all.
