Crotons are popular tropical houseplants that are most noted for their striking, colorful foliage. They can also be grown outdoors in subtropical and tropical climates. Because they’re so beautiful, you might want more. Propagating croton plants is easy. There are two options: cuttings and air layering.
If you love your croton and its beautiful colors, why not create more? Croton plant propagation is simple, although it does tend to root slowly. With patience, you’ll get new plants to keep or share.
A stem cutting is an easy and straightforward way to propagate a favorite croton plant. Take a cutting that is about 3 to 4 inches (7.5 to 13 cm) long and that has at least 3 leaves on it.
Use a standard rooting hormone for the best results. Dip the cut end of the stem into the hormone powder and plant it in a small container with good quality soil. Keep the soil consistently moist. Don’t let it dry out, but also avoid letting it get soaking wet.
Keep your cutting in a sunny spot with consistently warm temperatures, about 70 to 80 degrees F (21-27 C). As long as it stays within this range, the cutting should start to grow roots within a month.
Wait to transplant the cutting until it has some established roots. You should also see some new growth. Young leaves are green and only develop their striking colors as they mature.
Air layering is another technique for propagating plants that works with croton. This is a great technique for a large houseplant that has become leggy and could benefit from more branching. It’s not best for a small plant.
Air layering croton and other plants involves growing new roots before making a cutting. When you do this on croton, you get a new plant and encourage a new branch to make the original plant
