How to Cultivate and Care for Ground Cherries
Planting Ground Cherries
Ground cherries, also known as husk tomatoes, are native to North America and are relatively easy to grow. They can be started indoors 6-8 weeks before the last frost date or directly outdoors once the threat of frost has passed. Choose a sunny location with well-drained soil. Plant seeds 1/4 inch deep and space plants 2 feet apart.
Caring for Ground Cherries
Sunlight: Ground cherries thrive in full sun, but can tolerate partial shade.
Soil: They prefer well-drained soil that is rich in organic matter and slightly acidic.
Water: Water regularly, especially during hot weather. Ground cherries need about an inch of water per week.
Temperature: Ground cherries grow best in temperatures between 55 and 65 degrees Fahrenheit. They can tolerate temperatures up to 85 degrees Fahrenheit, but frost can kill the plants.
Fertilizer: Amend the soil with compost or an organic fertilizer specifically for fruits and vegetables.
Harvesting Ground Cherries
Ground cherries are ready to harvest when the husks turn from green to tan and drop from the plant. Collect the fallen fruit and store it in the refrigerator for up to two weeks. Ground cherries can also be frozen for several months.
Varieties of Ground Cherries
There are several varieties of ground cherries, including:
- Aunt Molly’s: A popular variety with an upright growth habit.
- Cossack Pineapple: Known for its tangy-sweet flavor.
- Goldie: A low-growing variety with spreading stems.
Pests and Diseases
Ground cherries are generally resistant to pests and diseases, but they can be affected by:
- Whiteflies
- Flea beetles
- Hornworms
- Cutworms
- Fungal issues
Proper growing conditions and good sanitation can help prevent most problems.
Propagation
Ground cherries can be propagated via seeds or cuttings.
Seeds: Start seeds indoors 1/4 inch deep in an organic seed-starting mix. Keep the soil moist and warm until the seeds germinate.
Cuttings: Take 4-6 inch stem cuttings in late spring or early summer. Dip the cut end in rooting hormone and plant the cutting in a container with drainage holes filled with soilless potting mix. Keep the cutting warm and moist until roots form.
Growing Ground Cherries in Pots
You can grow ground cherries in containers to control their sunlight exposure and protect them from storms. Choose a container that is at least 8 inches deep and has drainage holes. Use an organic potting mix made specifically for fruits and vegetables.
Troubleshooting
How long does it take to grow ground cherries?
Ground cherries are ready to harvest 75-90 days after starting from seed.
Do ground cherries come back every year?
No, ground cherries are grown as annuals, but they reseed themselves prolifically.
How do I save ground cherry seeds?
Use fully ripe ground cherries and remove the husks. Cut the fruit open and squeeze the pulp with the seeds into a bowl. Discard the skins. Rinse the seeds thoroughly and air-dry them for a few days before storing them in a cool, dry place.
Are ground cherries easy to grow?
Yes, ground cherries are relatively easy to grow as long as they are provided with sufficient sunlight and moisture.
