Cossack Pineapple Ground Cherry

Ground cherries prefer well-draining soil with a pH level between 6.0-6.5. They can tolerate a range of soil types, including sandy, loamy, or clay soils. They prefer full sun exposure but can tolerate some shade, especially during the hottest part of the day. Ground cherries can be grown in containers or directly in the ground, and they require regular watering to maintain even soil moisture.

For earliest harvest, start seeds indoors 4-6 weeks before the last frost. Sow seeds 1/4" deep in well-moistened, sterile starting mix. Keep soil moist until germination has occurred (10-14 days). Placing a dome over the trays will help keep the soil moist without requiring frequent watering.

After danger of frost has passed, set plants outdoors 36" apart in rows 60" apart. Plants have similar growth habit to tomatoes and will likewise benefit from caging.

Insect Pests

Although not usually problematic, ground cherries can be affected by a number of insect pests, including aphids, whiteflies, spider mites, and flea beetles. Hand-picking or using insecticidal soap can help control these pests. Covering plants with row covers can prevent flea beetle damage, and hosing off plants with a strong stream of water can help dislodge spider mites. Regularly inspecting plants and promptly addressing any infestations can help prevent widespread damage.

Diseases & Other Problems

Ground cherries can be susceptible to several diseases, including early blight, powdery mildew, and verticillium wilt. To prevent these problems, practice good garden hygiene by removing crop debris and weeds, maintain proper soil moisture levels, and avoid overhead watering to reduce the risk of fungal diseases. Additionally, ground cherries can be susceptible to fruit cracking and sunscald. This can be prevented by ensuring consistent moisture and providing shade, if needed.

Ground cherries are ready to harvest when the papery husk surrounding the fruit turns brown and dries out. To harvest, gently twist or cut the fruit off the plant. Remove the husks and rinse the fruit in cool water. They can be eaten fresh, preserved as jam or pie filling, or dehydrated for a longer shelf life. Store ground cherries in a cool, dry place in a paper bag or open container. They can last for up to 2 weeks at room temperature or for several months in the freezer.

CONSIDERATIONS:

Ground cherries are self-pollinating plants with both male and female organs being present in the same flower. Therefore it is generally not necessary to isolate plants. It may be prudent, however, to isolate plants of different varieties by several feet or more to prevent accidental crossing by bees or other insects.

HARVESTING SEED:

To harvest ground cherry seeds, wait until the fruit is fully ripe and has fallen off the plant or is easily pulled off the stem. Collect the fruit and remove the papery husk that surrounds it. Rinse the fruit to remove any remaining debris or pulp. Crush fruit by hand or if processing a large number of fruit, place in a food processor fitted with a plastic blade. Decant the seed and pulp mixture by adding cold water, stirring, and allowing the seeds to fall to the bottom. Repeat until no pulp remains. Pour the seeds out on a coffee filter or paper towel and place in a warm, well-ventilated area until completely dry.

SEED LONGETIVITY:

Ground cherry seeds can remain viable for up to 4 years if stored properly. To ensure the seeds remain viable, store them in a cool, dry place in an airtight container.
