How to graft roses to increase the survival rate
Summary: This article discusses the contents of planting green plants and flowers, focusing on how to graft roses for a higher survival rate and the fastest rooting method for rose cuttings, with the following details:
Now that the bud points of the roses have already germinated, can they still be grafted onto the rosehip stems? If so, is the survival rate very low? This question is indeed true. Roses are flowers that germinate relatively early, and when the daytime temperature is above 10 degrees Celsius, they will start to sprout and germinate.
In this season, it is still possible to graft the bud points and branches of the roses onto the rosehip stems. When grafting, it is still necessary to choose bud points with a relatively low degree of germination, and the length of the germinated bud points should not exceed 1cm. The survival rate of the grafted roses is still relatively high, but the grafting method and operation technique must be correct. The usual methods for grafting roses in spring include bud grafting, cut grafting, and slot grafting.
I. Bud grafting. Bud grafting is generally performed on the smoother side of the rootstock. This method involves making a T-shaped incision on the rosehip stem with a grafting knife, then prying up the epidermis and cambium layer on both sides of the T-shaped cut. A bud point from the rose branch, slightly with some woody part and shorter than the length of the incision, is then taken and镶嵌 in the T-shaped cut on the rosehip stem. The grafting cut is then tightly wrapped with plastic tape. After about a week of wound healing, the bud point of the rose starts to sprout and grow, and the rose bud basically survives. The plastic film at the bud point is gently pried open with a toothpick, and the rose bud will quickly sprout and grow into a branch.

II. Cut grafting. Cut grafting is performed on the top cross-section of the rootstock. The cut is usually made on one side of the rootstock cross-section, and the width of the cut should be similar to the thickness of the scion branch to allow the cambium layers to align. A rosehip stem with a diameter of 1.5cm can accommodate 2 to 4 scions, with the cut length generally around 2cm. The scion branches are cut into a wedge shape on both sides and then gently inserted into the cut, trying to align the cambium layers on both sides with the rootstock, at least one side must align. Then, the scion is tightly wrapped with plastic film. The cut interface of the rootstock and the top cut of the scion should also be sealed with plastic film to reduce the evaporation and loss of moisture at the cut, thus improving the survival rate of the scion.
