What kind of weather is best for grafting fruit trees?

Grafting is best done in a greenhouse. In high temperature season, shading nets or grass curtains should be used to shade seedlings to avoid excessive wilting of seedlings and affect their survival. For example, grafting eggplant at the end of winter in August is in the high temperature period, and heatstroke prevention is the key. In the low temperature season (such as the grafting of cucumber and cucurbitaceae in late September+10/early October, 65438), heat preservation is the main factor, and low temperature is not conducive to wound healing. The suitable temperature for grafting should be 25-28℃, and the relative humidity of air should be above 80%. When the humidity is not enough, use a sprayer to spray water into the air or wall to increase the humidity.
