Ground Cherry Plant Growing Guide: Care, Harvest and Uses

The ground cherry plant is one of my favourite crops due to easy cultivation and tangy but sweet berries. It is a compact plant that hides the marble-sized golden fruits in papery husks. I particularly enjoy using them for jams, salsas, and salads. 

If you want to plant these annuals in the upcoming spring, come along and read this article to learn all the necessary information about ground cherries, from initial planting to harvesting and storage.

Ground Cherry Planting Steps

For planting ground cherries, you can start the seeds indoors 6-8 weeks before the last spring frost or outdoors after the threat of frost has passed. You may plant the ground cherry seedling in containers, raised beds, or garden beds. 

Here are the planting steps for ground cherry plants:

• Step 1: Start the seeds indoors about 6-8 weeks before the last spring frost. Press the seeds lightly onto the soil surface without covering them completely, as they need light to germinate.
• Step 2: Harden off the seedlings for 5-7 days by gradually exposing them to the outdoor environment when the nighttime temperatures are above 50°F.
• Step 3: Choose a planting site that gets ample sunlight and has well-draining, loamy soil amended with compost.
• Step 4: Space plants at least 2 feet apart and plant them at the same depth as in their previous container. 
• Step 5: Water the plant deeply and mulch around the plant by applying a 2-inch layer of straw or shredded leaves. This will help retain moisture and keep the future fallen fruits clean.

Smart Tip

Check the planting site to ensure it does not have taller trees and shrubs that might shade the plants during the day.

How to Care for Ground Cherry Plants

How to grow ground cherries? For caring for these plants, you have to place them in a location with full sun and well-draining soil. Additionally, water them once a week and feed them with organic fertilizers to encourage fruit production. 

Let’s see the husk cherry care measures:

1. Sunlight Needs 

The husk cherry plant does best in full sun. It needs at least 6 hours of sunlight a day to grow optimally. The tree can grow in less sun exposure, but it will likely fruit less. 

2. Soil Requirements 

These plants are tolerant of various soil types and aren’t considered picky about it. However, they thrive best in well-drained soil that is rich in organic matter and has a slightly acidic pH.

3. Watering Frequency 

Ground cherries plant prefer well-moist soil and require about 1 inch of water per week. In dry conditions, it often drops the blossoms without producing fruit. Plan to water the plant at least once a week and potentially more in hot weather conditions.

4. Temperature and Humidity 

The ground cherry tree has good heat tolerance in its growing zones. The ideal temperature range for growing ground cherry is from 55°F to 65°F, though it can tolerate temperatures as high as 85°F. However, frost kills the plant. 

Humidity is not an issue with these plants; typically, 40% to 70% is best for them, which matches normal indoor and outdoor conditions.

Smart Tip

If you are growing ground cherries in cooler climates and frost threatens them before the ripening of fruits, cover the plants with row covers or with a piece of fabric to protect them.

5. Fertilizer

Amend the soil with compost while planting ground cherries. If the soil is poor, mix organic fertilizer to encourage fruit production. Avoid feeding heavy nitrogen, which can dull the flavour.

Smart Tip

Use tomato cages, wooden stakes, or twine to support the plants and keep them upright.

Harvesting and Storage of Ground Cherries

Ground cherries are generally harvested from the ground, not from the plant. During the growing season, from summer into fall, the plant produces fruits. Pick the fruits often and store them in a dry, well-ventilated space or freeze them for long-term use.

• Check daily as the ripe husks become tan and papery. Fruits typically drop off on their own when they are ready to be harvested.
• Gather the fallen fruits by hand, avoiding squeezing them. Many growers place a container or cloth under the plant to make the harvesting more convenient.
• Check the colour, as the best flavour is when they are amber to deep gold. The fruit should be slightly soft to thumb pressure.
• The husked berries can be stored in a dry, well-ventilated spot for about 2-3 weeks. If they are de-husked, consider refrigerating them for 7-10 days in the vented box.
• For longer use, spread them in a single layer on the baking sheet and freeze them until solid. Transfer them to a freezer bag where they can be used for 6 to 12 months.

Salads	Combine with avocado, cucumbers, and lime honey dressing to add sweetness to the greens.
Raisins	Dry the fruits until they become leathery to make tangy and potable raisins. Store them in an airtight container for long-term use.

Note: Eat only the ripe, de-husked fruits, as the leaves, husks, and unripe fruits are not edible and are considered toxic to humans and pets. Seek medical help immediately if the toxic part is consumed.

Propagation Method for Ground Cherries

These plants are typically propagated through the seeds, but you can also root the softwood cuttings to grow them. In the spring or early summer, take a cutting and root it in the free-draining medium. This is an easy and inexpensive way to create a new plant. 

Let’s see the steps of how to plant ground cherries from cuttings:

• Step 1: Take a 4-6 inch long cutting from the plant and remove the leaves from the bottom.
• Step 2: Dip the cut end in the rooting hormone.
• Step 3: Fill a container with soilless potting mix and place the cuttings into it. Ensure it has drainage holes. Keep the pot in a warm spot with bright indirect sunlight.
• Step 4: Water the soil well, and within a couple of weeks, the roots will form. Transplant it to the ground once you notice new growth on the stem.

Did you know?

People often confuse ground cherries with tomatillos. Tomatillos are called the Mexican husk tomatoes, while ground cherries are known as the husk tomatoes. Both belong to the same genus, but ground cherries are smaller and orange, while tomatillos are comparatively larger and green.

Pests, Diseases, and Other Issues in Ground Cherries

Husk cherries plant is generally hardy when compared to same family plants like tomatoes and tomatillos. But they can be affected by pests like aphids, whiteflies, and cutworms. They can also suffer from diseases including powdery mildew and leaf drop. 

Let’s see the pests and diseases and their easy solutions in these plants:

Pests in Husk Cherry Plants 

Pests	Solutions
Aphids	Wash with a stream of water and invite lacewings and lady beetles.
Cutworms	For two weeks after transplant, use collars to prevent them.
Whiteflies	Ventilate the space and monitor with yellow sticky cards.
Flea Beetles	Install floating row covers over transplants. If the seedlings are healthy, they outgrow the minor nibblings.

Diseases in Husk Cherry Plants 

Diseases	Solutions
Leaf drop and early blight	Cage the plants to improve airflow, avoid overhead watering, and do mulching and crop rotation.
Powdery mildew	Prune lightly and avoid overhead watering.

Other Issues in Husk Cherry Plants

Issues	Solutions
Abundant blooms but no fruits	Low pollinator traffic and cool night temperatures can cause this. Plant two or more plants and add bee plants.
Fruits drop unripe	Heat and irregular watering may lead to this issue. Keep the plant well moist and mulched.
Bland flavour profile	Too much nitrogen feeding and shade are the causes of this. Move the plants to a sunny spot, and don’t feed them high-nitrogen fertilizers.
Self seedling	In warm climates, the plant may self-seed. Harvest the fruits promptly and mulch it deeply to prevent the spread.

Smart Tip

To minimize self-seeding, grow these plants in a container or on a concrete deck or patio.
