Leaf shapes vary from oval to narrow
Stiff, woody stems

Height: 0.6 to 2m
Spread: 0.3 to 1m
Leaves: green, yellow, red, orange, evergreen

Common problems

Spider mites — These tiny pests thrive in dry indoor air and cause stippling on the leaves.
Mealybugs — They appear as white cottony masses in leaf axils and suck sap from the plant.
Leaf drop — Sudden changes in temperature or light often cause the plant to shed its leaves.

Growing it

Propagation: cuttings, air layering
When to plant: spring, summer
Overwintering: Bring the plant indoors before temperatures drop below 55 degrees. Keep it in a bright spot away from cold drafts and reduce watering slightly.
In containers: Crotons grow very well in containers and prefer a pot that is just large enough for their root system.

Stem Cuttings

Take a 4 to 6 inch cutting from a healthy stem.
Remove the lower leaves to expose nodes.
Place the cutting in a glass of water or moist potting mix.
Keep it in a warm, bright location until roots develop.

Group plants with similar humidity needs together to create a microclimate that keeps them all happy.
