Last spring, when I was grafting fruit trees, I had some leftover scions that I didn’t use immediately. Instead of discarding them, I buried them in the shade under the soil. A few weeks later, around mid-June, I suddenly remembered about them. At that time, the branches and leaves on the rootstock were already lush, and some fruit had even started to form. I realized those scions couldn’t be used anymore. So I took them out, soaked them in clean water for 10 hours, then prepared them on the anvil and Shandian anvil. I also removed any sprouts that had started to grow. To my surprise, all of them survived. The next year, I repeated the same experiment between late June and early July, and the survival rate was still very high. This test challenged the common belief that grafting fruit trees during summer is not possible.
The key to achieving a high survival rate lies in the technique. First, you need to cut the rootstock at a smooth spot, then make vertical cuts. The depth should be adjusted based on the thickness of the rootstock, allowing for flexibility. Next, prepare the scion by making a matching cut and insert it into the vertical opening. Make sure the cambium layers are aligned, and only expose about one millimeter of white tissue. Then apply a thin layer of yellow paste to help the graft heal. Finally, wrap the area tightly with a plastic strip. It’s best to leave two strong shoots on the scion, and don’t forget to seal the top cut with beeswax.
During the summer, it's crucial to keep the scions in a cool environment and prevent them from sprouting before grafting. Before using them, soak the scions in clean water for 10 to 24 hours to rehydrate them properly. This preparation helps ensure they remain viable and increases the chances of successful grafting.
