Reliance is a vigorous, trouble-free grape that needs three things to thrive: full sun, well-drained acidic soil, and a sturdy support to climb. Here is how to get your vine settled and producing.
Planting
- Unbox right away. Remove packaging, check the soil moisture, and water if the root zone feels dry. Keep the vine in bright light until you can plant.
- Pick a full sun site. Choose a spot with at least 6 to 8 hours of direct sun and good air movement, which helps keep foliage dry and disease-free.
- Check the soil. Reliance performs best in well-drained, slightly acidic soil. Amend heavy clay with compost and avoid low spots where water stands.
- Dig and set. Dig a hole twice as wide as the root ball and just as deep. Set the vine so the crown sits level with the surrounding grade, backfill, and firm gently.
- Install support first. Put your trellis, arbor, or two-wire fence in place at planting time so you are not disturbing roots later. Space multiple vines 6 to 8 feet apart.
- Water in and mulch. Soak thoroughly after planting and add 2 to 3 inches of mulch, keeping it a few inches off the trunk.
Watering
- First season. Water deeply once or twice a week while the root system establishes, more often in heat or sandy soil.
- Established vines. Grapes are drought tolerant once settled. Give a deep soak during extended dry spells, especially while fruit is sizing up.
- Avoid wet foliage. Water at the base rather than overhead to keep leaves and clusters dry.
Feeding
- Wait the first spring. Hold off on fertilizer until the vine shows new growth, then apply a balanced granular fertilizer.
- Feed annually. Fertilize once each spring as buds break. Do not overfeed with nitrogen, which pushes leaves at the expense of fruit.
- Keep soil acidic. Test every couple of years and use an acidifying amendment if your soil trends alkaline.
Pruning & Training
- Prune in late winter. Dormant pruning while the vine is leafless is essential for good fruit. Expect to remove most of the previous season's growth.
- Train a trunk. In year one, select the strongest shoot as the trunk and tie it to the support, removing competing shoots.
- Establish cordons. In year two, train two arms along the wire and shorten side canes to a few buds each for fruiting wood.
- Thin for airflow. Remove crowded or crossing canes each season so light and air reach the clusters.
Harvest
- Watch the color. Clusters turn rosy pink and soften as they ripen in late August.
- Taste to confirm. Grapes do not sweeten after picking, so sample a few berries before you harvest the cluster.
- Cut, don't pull. Snip clusters off with shears to avoid damaging the fruiting wood.
