Growing Colorful, Compact Shrimp Plants Is Easy—How to Do It Like a Pro

The shrimp plant, also known as Justicia brandegeana, is a tropical shrub with unique shrimp-like blooms in red, pink, and yellow shades. It originates from tropical regions of Mexico, Guatemala, and Honduras, but is grown in other warm, tropical climates.

The shrimp plant grows typically 3 to 4 feet high and wide. It has deep green leaves and clusters of vibrant, shrimp-shaped flowers that grow up to 2 inches long. It’s a popular plant among gardeners since it’s an evergreen perennial that requires minimal care.

Shrimp Plant Care

Here are the main care requirements for growing shrimp plants:

• Plant in moist, well-draining soil.
• Plant in partial shade in areas with harsh afternoon sun exposure, but ensure the plant receives at least 6 hours of sunlight a day.
• Mist with water periodically, especially if the plant is kept indoors.
• Feed with a balanced, all-purpose fertilizer every four to six weeks during the growing season.
• Prune annually after flowering.

Planting

The best time to plant a shrimp plant is in early spring. Place in an area with bright morning sun and well-draining soil. Allow at least 3 feet in between plantings.

Light

Shrimp plants will grow in full sun to partial shade, but placing shrimp plants where they will receive morning sun is ideal. These plants need bright sunlight, but the intense afternoon sun in tropical areas will cause the flowers to fade.

Soil

Shrimp plants need well-drained, loamy soil to prevent waterlog and root rot. The soil should also be slightly acidic to neutral (about pH 6.0 to 7.0) for optimal growth.

Water

Shrimp plants like moist soil, but avoid overwatering. Allow the top inch of soil to dry out before watering again.

Temperature and Humidity

Shrimp plants do best in tropical climates with temperatures consistently above 55°F. They need to be protected in cooler temperatures since they are sensitive to frost and freezing conditions. Mist regularly or use a humidifier nearby to maintain humidity.

Fertilizer

Use a balanced, all-purpose fertilizer during the spring and summer every four to six weeks. Avoid over-fertilizing, which can negatively impact the plant’s growth.

Types of Shrimp Plant

• Red-bracted shrimp plant: The red-bracted shrimp plant is one of the most common varieties of shrimp plants. It’s easily recognized by its bright red bracts that resemble shrimp and small white flowers.
• Yellow-bracted shrimp plant: This variety has the nickname “Yellow Queen” and is very similar to the red-bracted shrimp plant but is adorned with bright yellow bracts instead of red ones.
• Variegated: This shrimp plant variety also has colorful bracts and white flowers but stands out for its variegated green and white leaves.
• Compact: As its name implies, this cultivar is smaller than the standard shrimp plant, growing to about 2 to 3 feet tall and wide. It’s a perfect option for a pot or smaller gardens.

Pruning

The best time to trim and prune a shrimp plant is when blooming begins to slow in the winter and early spring.

Remove dead branches, flowers, and overgrowth to keep the plant trim and clean-looking. Regular pruning will encourage more growth and blooms in the plant.

Propagating Shrimp Plants

Propagation is the fastest way to multiply your shrimp plants. The best time to do it is in the spring when the plant is about to enter a growing phase.

The most effective propagation method is to use cuttings. It can take several weeks to a few months before roots develop from your cutting. You’ll need sharp shears or scissors, a well-draining potting mix, a pot, a plastic bag, and rooting hormone.

Follow these steps to propagate your shrimp plant:

1. Pick a mature, disease-free shrimp plant to cut for propagation.
2. Cut a 4- to 6-inch long stem with at least three sets of leaves just below a leaf node.
3. Dip the cut end of the plant in a rooting hormone.
4. Plant cutting in a pot with a well-draining potting mix with bright, indirect sunlight.
5. Place a plastic bag over the cutting to maintain humidity.
6. Remove the plastic bag occasionally to provide air circulation and water the cutting consistently.
7. Transfer the plant to a larger pot or your garden once roots start to form.

How to Grow Shrimp Plants from Seed

The best time to plant a shrimp plant from seeds is during the winter if the plant will be kept indoors. Otherwise, it’s best to plant the seeds in early spring. It typically takes a shrimp plant two to three weeks to germinate.

1. Soak seeds in warm water for 24 hours to soften the seeds.
2. Plant seeds 1/4 inch deep in pots or small containers. Water the soil and cover the pot with a plastic bag.
3. Place pots in a warm, well-lit area.
4. Water regularly to keep the soil moist and remove the bag briefly every day to prevent mold from growing.
5. Transfer seedlings to larger pots or your garden once the seedlings have grown a few inches tall and have a few leaves.

Overwintering

Shrimp plants thrive in warm weather, so protecting them from frost and cooler temperatures is essential if your climate is susceptible to these conditions.

The best way to protect the plant is to bring it indoors in a pot. Place it in a bright, indirect light and keep the soil moist. If bringing the plant indoors isn’t an option, place a garden blanket over the plant to protect it from frost.

How to Get Shrimp Plants to Bloom

Shrimp plants typically bloom from spring into the fall. Blooming tends to slow in the winter, but most shrimp plants will bloom on their own every year as long as they remain in their ideal, warm environment.

If your shrimp plant isn’t blooming, make sure the soil is moist, but not too wet. Do some light pruning to encourage more blooms, keep the plant in bright, indirect sunlight, and avoid afternoon sun.

You can also try reducing the nitrogen content in your fertilizer and using a product with more phosphorus.

Common Problems With Shrimp Plants

Shrimp plants may be relatively easygoing but can still experience issues from time to time. Here are common problems with shrimp plants and how to solve them.

Yellowed Leaves

Yellowing leaves are a common problem with shrimp plants and are caused by various reasons, such as lack of sunlight or overwatering. To fix it, move your plant to a bright location if it’s potted.

Check the drainage of your pot to ensure the plant is able to drain properly and wait to water the plant until the top inch of the soil is dry. If none of these methods work, feed the shrimp plant with a balanced fertilizer to increase nutrients.

Drooping Leaves

Drooping leaves are caused by underwatering or lack of moisture in the soil. Water your plant thoroughly and consistently, but make sure to water only when the top inch of the soil is dry.

Leggy Stems

Leggy stems and lack of foliage are usually seen when the plant hasn’t been pruned in a while. Make sure to trim and prune leggy growth on your shrimp plant at least once a year to encourage fuller growth. If the plant still looks sparse, move it to a spot where it receives more light.

Black Spotted Leaves

If you notice black or brown spots on your shrimp plant’s leaves, this could be a sign of a fungal issue. Prune the spotted leaves and increase the air circulation near the plant. Apply a fungicidal spray if spots continue to reappear.
