Sensitive Plant Care : All That You Need To Know

The sensitive plant, native to South and Central America, is a tropical perennial that belongs to the pea family. Its scientific name, Mimosa pudica, translates to “shy” or “bashful” in Latin, which perfectly describes its characteristic leaf-folding behavior. When touched, the leaves of the sensitive plant respond by rapidly closing up, a phenomenon known as thigmonasty.

Aside from its unique leaf movements, the sensitive plant also produces beautiful pink, pom-pom-like flowers that add a touch of elegance to any indoor or outdoor garden. Its fern-like foliage and compact growth habit make it an attractive choice for both experienced and novice gardeners. This article explains in detail how to grow and care for sensitive plant.

Facts About Sensitive Plant

The leaves of the sensitive plant are highly sensitive to touch. When someone or something touches the plant, the leaves will immediately fold inward and droop. This response is a defense mechanism to protect the plant from potential harm.

The plant’s leaves have specialized cells called pulvini, which are responsible for the quick movement. These cells contain water and potassium ions. When the plant is touched, an electrical signal is sent through the cells, causing the water to move out of the cells and making them lose their turgidity. As a result, the leaves fold and droop.

While touch is the primary stimulus for the sensitive plant, it can also respond to other forms of stimulation. The plant can react to changes in temperature, light, and even sound. For example, a sudden drop in temperature or a loud noise can cause the leaves to fold and droop.

During the night, the sensitive plant exhibits a different behavior. The leaves of the plant fold up and close together, resembling a folded umbrella. This behavior is thought to be a protective mechanism against nocturnal herbivores.

In traditional medicine, the sensitive plant has been used for various purposes. The leaves and roots of the plant are believed to have medicinal properties and have been used to treat conditions such as asthma, diarrhea, and skin infections. However, it’s important to note that scientific research on the plant’s medicinal benefits is limited, and it should not be used as a substitute for professional medical advice.

FAQ About Sensitive Plant

Can I grow a sensitive plant indoors?

Yes, the sensitive plant can be grown indoors as a houseplant. It is well-suited for indoor cultivation as long as it receives adequate light and proper care. Indoor-grown sensitive plants may have a slightly slower reaction time to touch compared to those grown outdoors, but they can still exhibit the characteristic leaf-folding response.

Are sensitive plants safe for pets?

Yes, sensitive plants are generally safe for pets. However, it’s always a good idea to keep an eye on your pets when introducing any new plant into their environment. Some pets may be curious and attempt to nibble on the leaves, but the plant is not toxic. Still, it’s best to discourage excessive chewing or ingestion to prevent any potential digestive discomfort.

Are sensitive plants invasive?

Sensitive plants can be considered invasive in some regions with favorable growing conditions. In areas where the climate supports their growth, they can spread rapidly and outcompete native plant species. It’s important to check with your local agricultural extension office or gardening authorities before planting sensitive plants outdoors.

How To Care For Sensitive Plant

Providing the sensitive plant with the right growing conditions is crucial for its overall health and well-being. Here are the key factors to consider:

1. Sunlight

The sensitive plant thrives in bright, direct sunlight. Sensitive plants require about 6–8 hours of sunlight each day, though they can tolerate partial shade. It should be placed close to a window so that it may get enough of sunlight. If you’re growing the sensitive plant indoors, consider using artificial grow lights to supplement natural light.

2. Temperature

Maintaining a warm environment is essential for the sensitive plant. Temperatures between 65°F and 75°F (18°C and 24°C) are its preferred range. Avoid exposing it to cold drafts or extreme temperature fluctuations, as this can cause stress and hinder its growth.

3. Humidity

The sensitive plant thrives in high humidity levels. Consider using a humidifier or setting up a tray of water close to the plant to add more humidity if you live in a dry region. Misting the leaves regularly can also help create a more favorable environment.

4. Soil

Well-draining soil is a must for the sensitive plant. A mixture of potting soil, perlite, and peat moss works well to provide adequate drainage while retaining enough moisture for the plant’s roots. Avoid overwatering, as it can lead to root rot and other issues.

5. Watering

Keep the soil consistently moist but not soggy. When the top inch of soil appears dry to the touch, water the plant. During the winter months, reduce watering frequency to prevent waterlogged soil. Avoid overwatering as this may lead to the decay of the roots.

6. Fertilizer

During the growing season, which typically spans from spring to summer, feed the sensitive plant with a balanced, water-soluble fertilizer every two weeks. For information on the proper dilution ratio, refer to the package directions. In the dormant period, reduce feeding to once a month or suspend it altogether.

7. Pruning

Prune the sensitive plant to maintain its desired shape and size. Use clean, sharp pruning shears to remove any dead, damaged, or overgrown foliage. Regular pruning also encourages bushier growth and prevents the plant from becoming leggy.

8. Pest and Disease Control

The sensitive plant is generally resistant to pests and diseases. However, it can occasionally attract common houseplant pests such as aphids and spider mites. Regularly inspect the leaves and stems for any signs of infestation, and treat them with organic insecticidal soap or neem oil if necessary.

9. Repotting

If you have a sensitive plant (Mimosa pudica) and it’s starting to outgrow its current pot, it’s time to consider repotting. Repotting your sensitive plant not only provides it with more space to grow, but it also allows you to refresh the soil and ensure optimal health for your plant.

When selecting a new pot for your sensitive plant, opt for one that is slightly larger than its current pot. This will give the plant room to grow without being overly stressed. In order to avoid waterlogging, make sure the pot includes drainage holes.

Before repotting, prepare a well-draining soil mix for your sensitive plant. A combination of equal parts potting soil, perlite, and peat moss works well. This mix will provide the necessary nutrients and aeration for healthy root growth.

Carefully remove your sensitive plant from its current pot by gently loosening the soil around the edges. Be cautious not to damage the delicate roots. If the plant is root-bound, gently tease the roots apart to encourage new growth.

Fill the bottom of the new container with a layer of the prepared soil mixture. Position your sensitive plant in the center and fill the remaining space with the soil mix, ensuring that the roots are well-covered. Gently press down the soil to eliminate any air pockets. After repotting, thoroughly water your sensitive plant to help settle the soil.

10. Overwintering

As sensitive plants are tropical in nature, they are not frost-tolerant and cannot survive in cold temperatures. Before the first frost hits, it’s important to bring your sensitive plant indoors. Choose a bright location with direct sunlight, such as near a south-facing window. Maintain a temperature of around 60-70°F (15-21°C) for optimal growth.

How To Propagate Sensitive Plant

1. Propagating Through Seeds

Plant propagation from seeds is an enjoyable and economical way to grow more plants if you’re a hobbyist with a green thumb.

Follow these steps to propagate sensitive plant seeds:

1. Fill the planting containers or pots with moist potting soil.
2. Make tiny, 1/4-inch-deep holes in the ground.
3. Place one or two sensitive plant seeds in each hole.
4. Add a thin layer of potting soil over the seeds.
5. Lightly mist the soil with water using a watering can or spray bottle.
6. Label the containers or pots with the date of sowing and the plant variety.
7. Cover the containers or pots with a clear plastic bag or plastic wrap to create a greenhouse-like environment.
8. Place the containers or pots in a warm location with indirect sunlight.
9. Maintain a temperature between 70-85°F (21-29°C) for successful germination.
10. Keep the soil consistently moist, but not waterlogged.
11. Do not overwater; this can result in fungus-related illnesses.
12. If the soil begins to dry out, regularly check its moisture content and spray water on it.
13. Remove the plastic bag or plastic wrap once the seedlings start to grow.
14. The seedlings should be placed in an area with strong, indirect sunshine.
15. Regularly water the seedlings, making sure the soil is damp but not soggy.
16. Every two weeks, give the seedlings a balanced liquid fertilizer feed.
17. Thin out the seedlings if they become overcrowded, leaving only the strongest ones.
18. Once the seedlings have produced a couple sets of genuine leaves, transplant them into individual pots.

2. Propagating Through Cuttings

Selecting the Parent Plant

When propagating sensitive plants, it’s important to choose a healthy and mature parent plant. Look for a plant that has vibrant foliage, is free from pests or diseases, and has strong stems. This will ensure that the cuttings you take have the best chance of rooting successfully.

Taking Cuttings

Using clean and sharp pruning shears or scissors, carefully take 4-6 inch cuttings from the parent plant. Make sure each cutting has at least 2-3 pairs of leaves. It’s best to take cuttings from the tips of the branches, as these are younger and more likely to root successfully.

Preparing the Cuttings

Remove the lower pair of leaves from each cutting, leaving only the top 2-3 pairs of leaves. This will help prevent the cuttings from losing too much moisture while they root. If desired, you can dip the cut end of each cutting in rooting hormone to promote root growth.

Planting the Cuttings

Fill small pots or containers with well-draining potting mix. Make a small hole in the center of each pot and gently place a cutting into the hole. To make sure there is good contact, firmly press the earth surrounding the cutting. You can plant multiple cuttings in the same pot, but make sure they are spaced apart to allow for proper growth.

Providing the Right Environment

Sensitive plants thrive in warm and humid environments, so it’s important to create the right conditions for your cuttings to root. The pots should be placed in a warm area with indirect, bright light. If you want to maintain high humidity and create the effect of a miniature greenhouse, you can cover the pots with plastic wrap or a clear plastic bag.

Watering and Care

Keep the soil moist but not waterlogged. To prevent the cuttings from being dislodged, lightly water them with a watering can or spray bottle. It’s important to monitor the moisture levels regularly and adjust your watering routine accordingly. Avoid flooding your plants too much since this could lead to root rotting.

Rooting and Transplanting

The cuttings should show signs of root formation after a few weeks. This is a sign that they have successfully rooted. Once the roots are well-developed, you can gently transplant the cuttings into larger pots or directly into your garden. Make sure to acclimate the new plants to their new environment gradually.

Caring for Propagated Plants

Once your propagated sensitive plants are established, you can care for them as you would care for mature plants. Here are some general care tips:

• Keep the soil uniformly moist by giving the plants regular waterings.
• Provide bright, direct light for optimal growth.
• Protect the plants from extreme temperatures and drafts.
• Throughout the growing season, Plants should be fertilized with a balanced fertilizer.
• Keep an eye out for illnesses and pests, and take appropriate action when needed.

Common Challenges and Troubleshooting

Despite its hardy nature, the sensitive plant may face some challenges along the way. Here are a few common issues and how to address them:

1. Leaf Dropping

If your sensitive plant starts dropping leaves, it may be a sign of overwatering, underwatering, or exposure to cold temperatures. Adjust your watering schedule and ensure the plant is kept in a warm environment. If the issue persists, check for any signs of pests or diseases.

2. Leaf Curling

Leaf curling can be caused by insufficient light, low humidity levels, or underwatering. Ensure your plant is receiving enough light and increase humidity by misting or using a humidifier. To maintain a constant moisture level in the soil, modify your watering schedule.

3. Lack of Leaf Movements

In some cases, sensitive plants may stop exhibiting their characteristic leaf-folding behavior. This can be due to environmental factors, such as low light levels or stress from improper care. Ensure your plant is receiving adequate light, water, and nutrients to stimulate leaf movements.
