Planting Calendar (Zone 6b/7a)
| Method | Timing | Notes |
|---|---|---|
| Start indoors | March 15 - April 1 | 6-8 weeks before last frost. Tiny seeds—barely cover. 70-80°F. Germination 7-21 days. Slow starters. |
| Direct sow | Not recommended in WV | Start indoors for reliable harvest. |
| Transplant | May 20 - June 5 | After frost danger. Harden off 7-10 days. Space 18-24" apart. Self-pollinating (single plant OK). |
| Days to maturity | 65-75 days from transplant | |
| Succession plant | N/A |

- Per season: 8-15 lbs per 10' row
Growing Conditions
- Soil: Well-drained, moderately fertile. Not fussy. 2" compost sufficient. Mulch heavily to keep fruit clean.
- Fertilizer: Light feeder. Compost at planting is usually sufficient. Avoid excess nitrogen.
- Companions: Tomatoes, peppers, herbs, marigolds

Heirloom & Recommended Varieties
'Aunt Molly's'
Polish heirloom with pineapple-vanilla flavor. 1/2" golden fruit. Incredible for jams, pies, and fresh eating. Self-sows readily.
'Goldie'
Similar to Aunt Molly's. Reliable, productive. Sweet tropical flavor. Great for preserves.
'Pineapple'
Extra sweet with pronounced pineapple flavor. Slightly larger fruit. Less productive but worth it for the flavor.
Cultural History & Domestication
Ground cherries are native to the Americas, closely related to tomatillos and Cape gooseberries. Native American tribes across eastern North America gathered them wild. Early European settlers adopted them enthusiastically. The Amish and Pennsylvania Dutch preserved the seed stock and culinary traditions, which is why several heirloom varieties bear Amish family names.
Seed Saving
Ground cherries are self-pollinating. Allow fruit to fall to ground when fully ripe. Collect fallen fruit, mash in water, viable seeds sink. Dry 1-2 weeks. Isolation distance: 100+ feet. Viability: 4-5 years. Self-sows prolifically—volunteers are common.
