Ground cherries (Physalis spp.) are native in many parts of the United States and often grow alongside roads. The plants have large, deep green leaves and tons of pale yellow flowers that develop into cherry-sized fruits. Start seeds of this frost-sensitive plant indoors six to eight weeks before your average last-frost date or buy transplants, which are increasingly available at nurseries and by mail order from seedsavers.org. Be sure to harden off seedlings before transplanting them outdoors.

Planting
Transplant ground cherries after all danger of frost has passed and the soil is thoroughly warm. Raised beds are best for growing ground cherries, especially in heavy clay soils, because the plants need good drainage. Work a couple inches of compost into the soil before planting. Like tomatoes, ground cherries sprout roots along their stems, so plant seedlings deeply, leaving three sets of leaves above the soil line. Set the plants 3 feet apart in rows 3 to 4 feet apart.

Ground cherries produce up to 300 fruits per plant and bear nonstop until frost. Four to six plants are sufficient for the average-sized family.

Growing Ground Cherries
Mulch lightly to suppress weeds and conserve soil moisture. Ground cherries thrive best with 2 inches of water per week. Spray the plants with diluted fish fertilizer when they set flowers and again two weeks later.

Harvesting
Ground cherries typically bear fruit about 70 days from transplant (late July to August in most regions) and continue until frost. The fruits have the peculiar characteristic of falling to the ground before they are ripe. Simply gather them up after they drop and keep them at room temperature in a basket without removing their husks. In a week or less, their color will deepen from light yellow to the warm apricot gold that signals ripeness. Store ground cherries in their husks. They will stay fresh for up to three months if placed in a mesh bag and kept in a cool place (50°F).

Troubleshooting
Ground cherry plants are susceptible to the same pests and diseases as tomatoes and tomatillos. Yet, perhaps because of their weed-like nature, ground cherries usually don't experience problems. Flea beetles and whiteflies can attack, especially if the plants are drought-stressed. Keep plants regularly watered and place floating row covers over them if these pests are particularly prevalent in your garden.
