Butterwort Plant Care: Tips for Keeping Your Carnivorous Plant Healthy

Butterworts are fascinating carnivorous plants that attract and trap insects with their slimy, slick coating on the leaves. These plants are also known as Pinguicula and belong to the Lentibulariaceae family.

Butterworts are passive trappers, meaning they do not actively capture prey like the Venus flytrap. Instead, their foliage is covered in tiny hairs that secrete mucilage that traps insects.

Once the insects are stuck, the plant releases digestive enzymes that breaks down the insect’s body and extracts the nutrients and minerals, such as nitrogen and calcium, from it.

There are many different species, varieties, and hybrids of butterworts, each with their own unique characteristics and care requirements.

Some species are best grown outdoors in temperate to warm zones, while others thrive in indoor conditions. When caring for butterwort plants, providing them with warm, indirectly-lit, and humid conditions is crucial.

In this article, we will explore the various aspects of butterwort plant care, including how to grow and care for these fascinating carnivorous plants.

Ideal Growing Conditions

When it comes to growing carnivorous butterworts, several factors must be considered to ensure they thrive. This section will cover the ideal growing conditions for butterwort plants and the differences between indoor and outdoor cultivation.

Indoor vs Outdoor Cultivation

Butterwort plants can be grown indoors and outdoors, but the ideal growing conditions differ.

Indoor Cultivation

When growing butterwort plants indoors, it’s essential to provide them with adequate sunlight. Place them near a south or west-facing window where they can receive at least 4-6 hours of direct sunlight daily. If natural light is unavailable, use grow lights to supplement the light.

Maintaining the right temperature is also crucial for indoor butterwort plants. They prefer temperatures between 60-80°F (15-27°C). Keep them away from cold drafts and air conditioning vents, as they can cause the plant to go into dormancy.

Indoor butterwort plants also require high humidity levels. Use a humidifier or place a tray of water near the plant to maintain humidity levels between 50-70%.

Outdoor Cultivation

Butterwort plants thrive in partial shade to full sun, depending on the climate. In hot climates, they prefer partial shade to protect them from the scorching sun. In cooler climates, they can tolerate full sun.

They also require well-draining soil and good air circulation. If planting in the ground, amend the soil with sand or perlite to improve drainage. If planting in a pot, use a well-draining potting mix.

During the winter, butterwort plants go into dormancy and require a dormancy period to regrow and bloom in the spring. In colder climates, they may require protection from frost and freezing temperatures.


Butterwort plants are suitable for USDA hardiness zones 8-10. In colder climates, they can be grown indoors or in a greenhouse.

Soil and Water Requirements

Butterwort plants require specific alkaline soil and water conditions to thrive. In general, they prefer well-draining soil that is low in nutrients. A mix of sphagnum moss, perlite, and sand is a popular choice for growing butterworts.

It is crucial to keep the soil consistently moist but not waterlogged when it comes to watering. The plant should never be allowed to dry out completely. The type of water is also relatively critical to the success of the Butterwort. Rainwater or distilled water is the best choice for watering butterworts, as tap water can contain minerals and chemicals that may harm the plant.

Good drainage is also crucial for the health of the plant. If the soil is too wet, the roots can rot. The pot should have drainage holes to allow excess water to escape.

Butterworts prefer slightly acidic to neutral soil with a pH between 5.5 and 7.5. If the soil is too alkaline, the plant may struggle to absorb nutrients. Adding sphagnum moss or peat moss to the soil can help to lower the pH.

In their natural habitat, butterworts are often found in boggy areas with live moss, granite, limestone, and pumice. However, it is not necessary to replicate these conditions exactly in cultivation. As long as the soil is well-draining and low in nutrients, the plant should be able to thrive.

Feeding and Fertilization

Butterworts are carnivorous plants that rely on insects for their nutrient needs. In the wild, they capture and digest small insects such as gnats, flies, and ants. When grown indoors, they may not have access to enough insects to sustain their growth and may require additional feeding.

Feeding butterworts can be done by placing them in a location where they can catch insects naturally. This can be achieved by placing the plants outdoors or near windows where insects are likely to fly in. Alternatively, small insects can be manually placed on the plant’s leaves to be digested.

Fertilization of butterworts is generally not necessary if they are being fed insects regularly. However, if the plants are not growing well or appear to be lacking nutrients, a small amount of fertilizer can be added to the soil. It is essential to use a fertilizer that is low in nutrients, as butterworts are sensitive to high fertilizer levels.

When fertilizing butterworts, it is recommended to use a fertilizer that is designed explicitly for carnivorous plants.

These fertilizers are typically low in nutrients and contain trace elements that are important for plant growth. Alternatively, a diluted solution of orchid fertilizer can be used.

When repotting butterworts, it is vital to use a well-draining soil mix that is high in organic matter. A mix of sphagnum moss and perlite or sand is ideal. Avoid using regular potting soil, as it can contain high levels of nutrients that can harm the plant.

Propagation Methods

Butterworts can be propagated through various methods, including seeds, leaf pullings, and division. Each method has its own advantages and disadvantages, and the choice depends on the grower’s preference and the availability of resources.


Growing butterworts from seeds can be a rewarding experience, but it requires patience and attention to detail. The seeds are tiny and require specific conditions to germinate successfully.

The best time to sow the seeds is in the spring when the temperatures are warm and the days are long.

The grower can use a seed tray or a plastic bag to germinate the seeds. The seed tray should be filled with a suitable soil mix, and the seeds should be sprinkled on top. The tray should then be covered with a plastic lid to create a humid environment.

The plastic bag method involves placing the seeds in a damp paper towel and sealing them in a plastic bag. The bag should then be placed in a warm, well-lit area.

Leaf Pullings

Leaf pullings are a quick and easy way to propagate butterworts. The process involves removing a leaf from the parent plant and placing it in a suitable growing medium.

The leaf should be inserted into the soil with the petiole end down, and the soil should be kept moist. After a few weeks, the leaf should start to sprout new growth.


Division is a method of propagating butterworts that involves separating the parent plant into smaller sections. This method is best suited for mature plants that have outgrown their pots.

The plant should be carefully removed from its pot, and the root ball should be gently teased apart. Each section should have a healthy root system and at least one rosette of leaves. The sections can then be potted up individually.

Potting and Repotting

Potting and repotting are essential aspects of butterwort plant care. Butterworts grow well in containers and require a well-draining and moist soil mix. It is a good idea to use a container that is slightly larger than the plant’s root system to avoid overwatering.

When repotting, it is essential to use a soil mix that is compatible with carnivorous plants. Mixing sphagnum moss, perlite, and sand is a good option. It is also recommended to sterilize the soil mix before use to prevent the introduction of harmful bacteria or fungi.

Butterworts have fibrous roots and do not need to be repotted frequently. Repotting every 3-5 years is sufficient. The best time to repot is in early spring when the plant is actively growing. It is essential to be gentle when handling the plant to avoid damaging the delicate leaves.

When repotting, remove the plant from its current container and gently remove dead leaves and any old soil from the roots. Trim any damaged or dead roots and place the plant in the new container with fresh soil mix. Water the plant thoroughly after repotting.
