🌾 Seed Saving

Method: 1. Choose fully ripe fruit from healthy plants—fruits will have dropped from plant or fall with gentle shake 2. Remove husk; fruit will be slightly sticky 3.

Squeeze fruit to release seeds into bowl of water 4. Ferment 1-2 days at room temperature (shorter than tomatoes) 5. Stir daily; viable seeds sink 6.

Pour off pulp and floating seeds 7. Rinse viable seeds in fine-mesh strainer 8. Spread on glass or paper plate; dry 1-2 weeks in shaded, ventilated area 9.

Seeds are very small—handle carefully 10. Store in paper envelope in cool, dry, dark place.

Note: Ground cherry seeds are tiny and numerous—one fruit yields 50-100 seeds.

Isolation Distance: - Primarily self-pollinating: Ground cherries are mostly self-fertile - Minimum: 50-100 feet between varieties - For seed sale: 200-500 feet or cage flowers - Note: Some crossing occurs via bees; isolate for pure varieties

Viability: 4-6 years under proper storage. Germination rates remain good through year 5.

Special Notes: - Ground cherries self-seed readily—fruits left on ground will germinate next year - For controlled seed saving, harvest fruits before they drop - One plant produces hundreds of fruits, each with many seeds - Save from 5-10 plants for genetic diversity - Select for flavor, productivity, and early maturity (important in Zone 6) - Volunteers (self-seeded plants) often produce earlier than transplants
