Frost® Peach Tree

Frost® Peach grows as an in-ground tree across USDA zones 5–9, reaching a mature 12–15 ft. tall and wide. Give it an open, sunny spot with room to spread; it is too large to keep long-term in a container, though young trees can be held in a large pot for a season or two before planting out.

Planting

1. Choose a site in full sun with good air circulation and well-draining soil — peaches resent wet, heavy ground.
2. Dig a hole as deep as the root ball and at least twice as wide, loosening the surrounding soil so roots can spread.
3. Set the tree so the graft union sits a couple of inches above the soil line; never bury the graft or plant too deep.
4. Backfill with native soil, firm gently to remove air pockets, and water in thoroughly to settle the roots.
5. Apply a 2–3 in. layer of mulch over the root zone to conserve moisture, keeping it pulled back several inches from the trunk to prevent rot.

Care & maintenance

• Water. Keep the soil evenly moist during the first growing season and through fruit development; deep, infrequent watering is better than frequent shallow sprinkling.
• Feed. Apply a balanced fruit-tree fertilizer in early spring as growth begins; avoid heavy late-season nitrogen, which pushes soft growth that won't harden before winter.
• Light & temperature. Full sun is essential for sweet fruit. Frost is hardy in zones 5–9 and tolerates colder winters than many peaches; site it where spring frosts are less likely to nip the early blossoms.
• 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 remove old wood to encourage fresh fruiting shoots.
• Pollinate. Frost is self-fertile, so a single tree will set fruit on its own — no pollinator partner needed.
• Pests & disease. Frost is highly resistant to peach leaf curl, its standout trait. Stay watchful for brown rot, aphids, and peach tree borer; good sanitation and dormant-season care keep most problems in check.
• Harvest. Fruit ripens in August. Pick when the ground color turns fully yellow and the peach gives slightly to gentle pressure and twists easily from the branch.

How does the Frost peach taste?

Frost delivers a classic, full peach flavor — sweet, juicy, and well balanced, with golden-yellow freestone flesh. Because it's a freestone, the pit separates cleanly, making it easy to slice for fresh eating, canning, or freezing.

Do I need a second tree to get fruit?

No. Frost is self-fertile, so a single tree will pollinate itself and set a full crop. Planting more than one simply gives you more fruit, not better pollination.

Why is Frost recommended for cool, wet climates?

Frost is celebrated for its strong resistance to peach leaf curl, the fungal disease that thrives in cool, damp springs and disfigures or defoliates susceptible peaches. That resistance lets it succeed in regions, such as the Pacific Northwest, where many other peaches fail.

How soon will it bear fruit?

Young peach trees typically begin bearing within about two to four years of planting, depending on tree size at planting, growing conditions, and care. Full sun, good pruning, and consistent watering all help it reach productive size sooner.

When and how do I harvest the peaches?

Frost ripens in August. Look for the background color to shift from green to a full yellow and a fragrant, slightly soft feel near the stem — a ripe peach lifts from the branch with a gentle twist. Pick over several days, as not all fruit ripens at once.

My tree dropped some young fruit — is something wrong?

Usually not. Peaches naturally shed a portion of immature fruit in early summer ("June drop") to support what remains. Thinning the rest by hand to roughly 6–8 in. apart improves size and sweetness and reduces limb breakage. Heavy or sudden drop can also signal drought stress or pest pressure, so check soil moisture and inspect the fruit if it seems excessive.
