Propagation of Croton gratissimus Burch. var. gratissimus
Croton gratissimus Burch. var. gratissimus, commonly known as the "forest feverberry" is a popular shrub among gardeners worldwide due to its attractive foliage and medicinal properties. These plants are propagated easily by various methods described below.
Seed propagation
Seed propagation is the most common method of propagating Croton gratissimus Burch. var. gratissimus. The ideal time to collect seeds is in autumn from ripe fruits.

Dip the end of the stem cutting in rooting hormone powder before planting it in well-draining soil mix and keep it moist until the roots form. Once the cutting is well rooted, transplant it into a separate pot or bed.
Air layering propagation
Air layering propagation is also another method for propagating Croton gratissimus Burch. var. gratissimus. Choose a healthy branch with mature leaves from an established plant. Make a deep cut in the branch, scrape off the bark and apply rooting hormone on the wounded area. Cover the wounded area with moist sphagnum moss and wrap it with a plastic bag to create a humid environment. After some weeks, roots will form. Cut the branch below the rooted part and plant it in well-draining soil mix.
In conclusion, Croton gratissimus Burch. var. gratissimus can be propagated by using various methods, including seed propagation, stem cutting propagation and air layering propagation.
