Stratifying Peach Pits for Successful Germination

Why Peach Pits Need Cold Treatment

Peach seeds have a physiological dormancy that prevents germination until they experience a prolonged cold period (stratification). Without it, the embryo remains inactive.

Two Stratification Methods

1. Refrigerator method: Plant pit 1 inch deep in moist potting mix in a pot. Seal pot in a plastic bag; refrigerate 90 days at 34–40°F. Then move to warm, bright spot; germination in 2–3 weeks.
2. Outdoor method: Plant pits in pots in autumn; leave outdoors all winter. Natural cold satisfies the requirement; seedlings emerge in spring.

Timing Tip

Start stratification in late fall/early winter so seedlings emerge at the right time for the growing season. Avoid starting in late spring/summer.

Important Note

Peaches from grocery stores are hybrids; seedling fruit will differ from the parent. For predictable quality, plant grafted trees.
