THE PROPER TIME TO PLANT grape cuttings is not well established. Growers generally plant cuttings in March and April. Cuttings are made in the winter and early spring and are stored in the soil or refrigerated until they are planted. The best depth and position in the soil for cuttings in storage have also not yet been determined. It is becoming a common practice to refrigerate graft-sticks, rootings and cuttings. The effects of this method of storage on subsequent rooting, and also the effects of the time of planting on rooting, needed researching.

John Peterson and field assistants of the Kearney Horticultural Field Station assisted in planting the cuttings, digging, grading and weighing the rootings.
