How to Grow and Care for Croton Plants

Print Friendly and PDF

The croton is an easy-to-grow houseplant known for its variegated foliage covered in green, scarlet, orange, and yellow splotches. Here’s how to care for a croton in your home or garden.

About Croton

Croton, also called “garden croton,” are native to the tropical forests of southeast Asia and Oceania. In the wild, they grow as large shrubs, reaching up to 10 feet tall (in the home or garden, they stay a lot smaller).

Note: All parts of this plant are poisonous—especially the seeds—so it is not recommended for use in homes with curious pets or children. When damaged, croton produce a milky sap that can be irritating to the skin, too.

Planting

Planting Croton

  • When choosing a container for your croton, keep in mind that the plant will grow upright, which eventually may cause it to become top heavy. Pick a container that won’t easily tip over when the croton gets larger. Or, plan to pot up to larger pots over time.
  • Use a well-draining potting mix. Croton like to be kept moist, but not wet.
  • In areas with warm, humid summers, croton can be grown outdoors as a unique and colorful landscape plant. They work well in tropical-themed containers or alongside annuals in the ground. When nighttime temperatures drop to around 50°F (10°C), croton will need to be taken indoors.
Growing

How to Care for Croton

  • Place croton in a sunny location such as an eastern, southern, or western window. If a croton is getting too little light, its newer leaves will be less colorful. 
  • Keep the soil evenly moist, but let it dry out between waterings.
  • If humidity is low in your home, mist around the leaves with water once a week or keep a tray of wet gravel near the plant.
  • Croton leaves are dust magnets. Gently wipe the leaves with a moist cloth twice a month to keep them clean and dust-free.
  • Fertilize the plant in spring and summer, while the plant is actively growing. In fall and winter, refrain from fertilize more sparingly or fertilizing altogether.
  • New croton plants can be started with 4- to 6-inch stem cuttings. Remove the bottom leaves and place the cutting in a glass of water. After roots have formed, plant in a small pot.
  • Repot the plant in the spring if it has grown too large for its current pot.

Recommended Varieties
  • ‘Petra’ is a popular cultivar. It has green leaves with red, orange, and yellow veins.
  • ‘Gold Star’ has green leaves that are splashed with bright gold “stars.”
  • ‘Eleanor Roosevelt’ has skinny leaves that range in color from burgundy to lime green. The leaves are mottled with bright yellow, as if they were spray painted.
  • ‘Oakleaf’ has oak leaf–shaped dark green or bronze leaves with veins in yellow, orange, and red.
Wit and Wisdom
  • Croton are members of the Euphorbiaceae family of plants, which makes them relatives of the poinsettia and the cast iron plant.
Pests/Diseases

Croton are usually pest and disease free, though they are susceptible to common houseplant pests such as mealybugs, spider mites, and scale insects.

Leaves keep dropping which look healthy and 1 of the stems has nodules of sap. What is the sap?
Thank you

I believe I have a croton plant. I'm wondering what the tiny spike like things are. A few of them look like new leaves growing at the tip of them. Hope I can get this figured out. Thank you.

Should I replant my croton in potting soil or tropical potting soil?? It's about a foot long

I have some crotons in my back yard I planted about 4 years ago. The nursery called them sloppy painter crotons; from the description above, I think they might be Eleanore Roosevelt. They have a thin green leaf and uneven yellow spots like paint splotches. I recently noticed some of the tops have a bumpy dark area (sort of moldy looking). Could anyone tell me what that might be and how should I treat it? I love these in my garden and would like them to last. My first thought is to treat them with Neem Oil
