Late winter into early summer is the best time to graft fruit trees. Much will depend upon the type of grafting you're doing. You want to have your root stock and collect your scion before the sap rises and buds begin to emerge.

When Should grafting be done?

Most grafting is done in late winter or early spring before new growth begins. The best time is after the chance of severe cold has passed but well before hot weather arrives. Scion wood may be collected during the winter. Store it in a cold, moist place at temperatures close to 34 degrees Fahrenheit.

Which month is suitable for grafting?

Unlike budding, which can be performed before or during the growing season, most grafting is done during winter and early spring while both scion and rootstock are still dormant.
