Crotalaria Plant Information

Crotalaria Plants are popular for their bright yellow or orange flowers and their ability to fix nitrogen in the soil, making them useful for crop rotation and soil improvement. Additionally, some species of Crotalaria are also used in traditional medicine for their anti-inflammatory and antimicrobial properties.

However, it is important to note that some species of Crotalaria Plants contain toxic alkaloids and should be avoided. Overall, Crotalaria plants are a diverse and interesting group of plants with both practical and medicinal uses.

Common Names: Devil-bean, Rattleweed, Shack shack, Rattlebox, Sun hemp and Wedge-leaf rattlepod.

How to Propagate Crotalaria Plant?


Crotalaria Plants can be propagated through seeds or stem cuttings. 

Seed Propagation

  1. Firstly, collect mature seed pods from a healthy Crotalaria plant. The pods should be dry and brown.
  2. Gently open the seed pods and collect the small seeds.
  3. Fill seed trays or pots with a well-draining potting mix.
  4. Sow the seeds on the surface of the potting mix, lightly pressing them into the soil.
  5. Cover the seeds with a thin layer of soil or vermiculite.
  6. Water the soil gently to provide moisture, but avoid overwatering.
  7. Place the trays or pots in a warm and sunny location, preferably with temperatures around 20-25°C (68-77°F).
  8. Keep the soil consistently moist until germination, which usually occurs within 1-2 weeks.
  9. Once the seedlings have grown to a suitable size, they can be transplanted into individual pots or directly into the ground.

Stem Cutting Propagation

  1. Firstly, select a healthy Crotalaria plant and identify a mature, non-flowering stem.
  2. Using clean and sharp pruning shears, cut a 6-8 inch section of the stem just below a node.
  3. Remove the lower leaves from the cutting, leaving only a few leaves at the top.
  4. Optionally, dip the cut end of the cutting in a rooting hormone powder to stimulate root development.
  5. Prepare a well-draining potting mix or a mixture of sand and peat moss.
  6. Plant the cutting into the potting mix, burying at least half of the cutting.
  7. Water the cutting thoroughly and place it in a warm and bright location with indirect sunlight.
  8. Maintain a humid environment around the cutting by covering it with a plastic bag or placing it in a propagator.
  9. Mist the cutting regularly to keep the humidity levels high.
  10. Roots should start to develop within 4-6 weeks. Once the cutting has established a strong root system, it can be transplanted into a larger pot or directly into the ground.

Requirements to Grow Crotalaria Plant

Crotalaria plants are sun-loving and thrive in full sun to partial shade. They require a minimum of 4-6 hours of direct sunlight daily to promote healthy growth and abundant flowering.

Placing them in a location that receives ample sunlight throughout the day will ensure optimal development and vibrant blooms.


Crotalaria plants prefer well-draining soil that allows excess water to flow away easily. They can adapt to various soil types, including sandy or loamy soil.

However, fertile soil enriched with organic matter, such as compost or well-rotted manure, provides the necessary nutrients for vigorous growth. Good drainage is essential to prevent waterlogging, which can lead to root rot.


Adequate watering is crucial for Crotalaria plants, especially during hot and dry periods. They require regular watering to keep the soil evenly moist. It’s important to avoid overwatering, as excessive moisture can lead to root rot and other fungal diseases.

Allow the topsoil to dry slightly between watering sessions, and adjust the frequency based on weather conditions.

Crotalaria plants are well-suited to the warm climates found in India. They thrive in temperatures ranging from 20°C to 30°C (68°F to 86°F). These plants are sensitive to frost and extreme cold, so it’s essential to protect them during the winter months.

Consider providing a sheltered location or covering the plants with frost blankets when temperatures drop.

Crotalaria Plant Care


While Crotalaria plants have nitrogen-fixing capabilities and can grow well in nutrient-deficient soils, providing additional nutrients can enhance their growth and overall health.

Incorporating organic matter, such as compost or well-rotted manure, into the soil during planting helps enrich the soil and provide essential nutrients.

Additionally, applying a balanced fertilizer during the growing season, following the instructions on the packaging, can further promote healthy foliage and abundant blooms.


Crotalaria plants generally require minimal pruning. However, removing any dead, damaged, or diseased branches is important for maintaining the Crotalaria Plant’s health and appearance.

Light pruning can be performed after the flowering season if you want to shape the plant or control its size. Pruning can stimulate new growth and result in a bushier plant with more abundant blooms in the following season.

Pests and Diseases

Crotalaria plants are known to be relatively resistant to pests and diseases. However, they may occasionally face issues such as aphid infestations or spider mites.

Regularly inspect Crotalaria Plants for signs of pests, such as distorted leaves or sticky residue, and take appropriate measures to control them. Additionally, using organic insecticides or introducing natural predators, like ladybugs or lacewings, can help manage pest populations.

Fortunately, Crotalaria Plants are generally resilient against diseases, but proper watering practices and good airflow can help prevent fungal infections.
