Contender is a full-size peach hardy in zones 5 through 9, maturing to roughly 12 to 15 feet tall and wide. It is best grown in the ground in a sunny, open spot with room to spread.
Planting
- Choose a site in full to part sun with good air circulation; a slight slope helps cold air and frost drain away from the blossoms.
- Plant in well-draining soil. Peaches resent wet feet, so avoid low spots where water collects after rain.
- Dig the hole about twice as wide as the root ball but no deeper than the roots came in their container.
- Set the tree so the graft union (the swollen knob low on the trunk) stays a couple of inches above the soil line; do not plant too deep.
- Backfill with native soil, water in thoroughly to settle out air pockets, then mulch the root zone while keeping mulch pulled back a few inches from the trunk.
Care & maintenance
- Water. Keep the soil evenly moist the first two seasons while roots establish, then water deeply during dry spells and especially as fruit sizes up in summer.
- Feed. Apply a balanced fruit-tree fertilizer in early spring as growth begins; avoid heavy late-season feeding that pushes tender growth into fall.
- Light & temperature. Give it full sun for the best crop. Contender is cold-hardy for zones 5 through 9 and carries enough chilling requirement to fruit dependably in colder regions.
- Prune. Prune in late winter while dormant, training to an open-center (vase) shape to let light and air into the canopy; peaches fruit on last year's wood, so renew that growth annually.
- Pollinate. Contender is self-fertile, so a single tree will set fruit on its own. A second variety is not required.
- Pests & disease. Watch for peach leaf curl, brown rot, and borers; a dormant-season spray program and prompt cleanup of dropped fruit and leaves go a long way toward control.
- Harvest. Fruit ripens in August. Pick when the ground color shifts from green to gold and the peach gives slightly to gentle pressure with a fragrant aroma.
