How to Grow Japanese Lantern Plant Outdoors

The Japanese Lantern Plant, also known as Physalis alkekengi, is a stunning plant that adds a touch of beauty and intrigue to any garden. With its vibrant orange lantern-like fruits and attractive foliage, it is sure to catch the eye of anyone passing by. If you are interested in growing this unique plant outdoors, here are some tips to help you get started.

Choosing the Right Location

The first step in successfully growing Japanese Lantern Plants outdoors is selecting the right location. These plants prefer full sun but can tolerate partial shade. Ensure that the area you choose receives at least six hours of direct sunlight daily.

It is also important to consider the soil conditions. Japanese Lantern Plants thrive in well-draining soil that is rich in organic matter. If your soil is heavy or clay-like, consider amending it with compost or peat moss to improve drainage.

Propagation Methods

There are two primary methods of propagating Japanese Lantern Plants: by seeds or by division.

Seeds: To start from seeds, sow them indoors 6-8 weeks before the last frost date or directly into the ground after the danger of frost has passed. Sow the seeds on the surface of the soil and lightly cover them with a thin layer of soil. Keep the soil consistently moist until germination occurs, which usually takes about 2-3 weeks.

Division: Another way to propagate Japanese Lantern Plants is through division. This method is best done in early spring or fall when the plant is dormant. Simply dig up an established plant and carefully divide the root ball into smaller sections, ensuring each section has several shoots. Replant the divisions in their desired locations, making sure they are at the same depth as before.

Planting and Care

Once you have selected an appropriate location and propagated your Japanese Lantern Plants, it’s time to plant them and provide proper care.

Planting: Dig a hole that is twice as wide and as deep as the root ball. Place the plant in the hole, making sure the top of the root ball is level with or slightly above the soil surface. Backfill the hole with soil, gently firming it around the plant. Water thoroughly after planting to help settle the soil.

Watering: Japanese Lantern Plants require regular watering, especially during dry periods. Water deeply and consistently to keep the soil evenly moist but not waterlogged. Avoid overhead watering, as wet foliage can lead to fungal diseases.

Mulching: Applying a layer of organic mulch around the base of the plant helps retain moisture, suppress weed growth, and regulate soil temperature. Use materials like straw, wood chips, or shredded bark and maintain a thickness of 2-3 inches.

Fertilizing: Japanese Lantern Plants are relatively low-maintenance and do not require heavy fertilization. However, incorporating compost or well-rotted manure into the soil before planting can provide essential nutrients. Additionally, you can apply a balanced slow-release fertilizer in early spring to promote healthy growth.

Pruning: Pruning is not necessary for Japanese Lantern Plants but can be done to control their spread or shape them according to your preference. If needed, prune the plants in early spring before new growth begins.

Dealing with Pests and Diseases

While Japanese Lantern Plants are generally resistant to pests and diseases, there are a few issues you may encounter:

Aphids: These small, soft-bodied insects may feed on the foliage and stems of the plant. Use insecticidal soap or a strong blast of water to remove them.

Slugs and Snails: These slimy creatures can chew on leaves and fruits. Use organic slug and snail baits or create barriers around your plants using copper tape or crushed eggshells.

Powdery Mildew: This fungal disease can cause a powdery white coating on the leaves. Improve air circulation around the plants by pruning and thinning them. If necessary, apply a fungicide labeled for powdery mildew control.

Harvesting and Winter Care

The most distinctive feature of Japanese Lantern Plants is their lantern-like fruits that develop in late summer or early fall. These fruits start out green but gradually turn bright orange as they ripen. Harvest them when they are fully mature and the husks have dried and become papery.

In colder climates, Japanese Lantern Plants may die back to the ground in winter. Cut back the foliage after it has died and apply a layer of mulch around the base of the plant to protect it from extreme temperatures.

Conclusion

Growing Japanese Lantern Plants outdoors can be a rewarding experience for any gardener. By providing them with the right location, proper care, and protection from pests and diseases, you can enjoy their unique beauty year after year. So why not give it a try and add a touch of enchantment to your garden with these stunning plants?
