Becoming familiar with these standards is important to help you make decisions on plant material and can make the difference between success and failure of a new vineyard. Rooted cuttings are graded by nursery industry standards. Most grapevines are sold as dormant rooted cuttings and are either grafted or own-rooted. Never allow the roots to dry out, as this will lead to poor growth or vine death. Water the heel bed periodically to keep the roots moist but not wet. Do not store vines in water or a refrigerator for long periods of time. This is known as “heeling-in.” Vines will remain healthy in the heel bed for up to four months. If vines are received before the site is ready for planting (e.g., soil preparation, irrigation set up or trellis construction has not been completed), unpack the vines and cover them with soil in the shade until planting. ![]() This will prohibit the vine from growing optimally and may lead to death. Storage of dormant vines leads to desiccation of the roots and buds. Once delivered, vines should be planted immediately, if possible, and not stored. ![]() The nursery should ship the vines at or near your desired timeframe around planting. For example, you will probably miss out on the best rooted cuttings (often termed #1), and poor quality vines can be too weak to survive. If you wait until January or February to order, you could have problems with plant availability and/or quality. To ensure the highest quality vines and a specific cultivar or rootstock, order vines from a reputable nursery in the summer or early fall prior to planting in spring. In most of the U.S., the best time to plant grape vines is very late winter or early spring, if irrigation is available. Photo by Patty Skinkis, Oregon State University. Do not bury them too deep into the soil as root constriction may occur.Įarly spring is a good time to plant grape vines. If you are using grow tubes, install them after planting, lightly covering the base with soil to exclude herbicide sprays. Be sure to remove the vine from pots before planting. Do not plant potted vines until after the risk of frost has passed in the spring. Green growing (potted) vines should be acclimated to seasonal weather conditions in a protected area for a few days prior to planting. The amount and frequency of irrigation will vary depending on region and environmental conditions. Do not allow weeds to grow near the vine row, and keep the young vines well watered.As new shoots begin to grow, watch for signs of pest damage that may inhibit vigorous growth.Water the vine with two or three gallons of water immediately after planting.Install a stake next to the vine to provide stability.If you are using grafted vines, make sure the graft union is above the soil line by approximately 6 inches. Stand the plant in the hole and pack the same soil back into the hole around the plant.Immediately prior to planting, trim the roots to fit the hole and cut the top growth back to only two to three buds (above the graft union on grafted vines) on the strongest cane.In this situation, break up the glazed areas using a shovel or equivalent tool. ![]() In soils with high clay content, glazing of the sides of the hole may occur, which can impede root growth.
