Croton Plant Care Guide

Written By Jennifer Bruce

Croton plants, also known as Codiaeum variegatum, are tropical shrubs or small trees native to Southeast Asia and Australia. The croton has been a popular houseplant for centuries. This plant care guide will walk you through successfully growing a croton plant.

Croton plants prefer bright, indirect light and will thrive in a location that receives plenty of indirect sunlight. However, they can also tolerate lower light levels and can survive in a range of lighting conditions. It is important to avoid placing crotons in direct sunlight, as this can cause the leaves to fade or become scorched. Instead, try to provide the plant with bright, indirect light, such as near a south- or west-facing window. Read our sunlight exposure guide for more information on sunlight terminology.

  • Codiaeum variegatum

  • Euphorbiaceae

  • Full Sun to Partial Shade

  • pH 4.5-5.5

  • Toxic to Cats and Dogs

  • Zones 9-11 (USDA)

Croton plants do not have specific humidity requirements and can thrive in a range of humidity levels. However, they do prefer a moderate level of humidity and may benefit from being misted or placed on a humidity tray. If the air in your home is particularly dry, you may need to take steps to increase the humidity around your croton plant. This can be done by using a humidifier, placing the plant on a humidity tray, or misting the plant with water regularly.

Croton plants prefer warm temperatures and will thrive in a location that stays between 65 and 85 degrees Fahrenheit. They are sensitive to cold temperatures and should be protected from drafts or sudden temperature changes. It is important to keep crotons away from windows or doors that may allow cold air to reach the plant. In addition, it is a good idea to avoid placing crotons near air conditioning vents or other sources of cold air. Crotons can tolerate a wide range of temperatures, but it is important to provide them with a consistently warm environment for optimal growth.

Croton plants should be watered regularly, but allowing the soil to dry out slightly between waterings. Overwatering can lead to root rot, so it is important to make sure the soil has good drainage and to avoid letting the plant sit in standing water. The frequency of watering will depend on a number of factors, including the size of the plant, the type of soil it is planted in, and the humidity and temperature of the surrounding environment. A good rule of thumb is to water the plant when the top inch or so of soil feels dry to the touch.

Croton plants prefer a well-draining soil mix with a slightly acidic to neutral pH. A good soil combination for crotons would be a mix of equal parts potting soil, peat moss, and perlite or sand. This will help to provide the plant with the nutrients it needs, while also improving drainage and aeration. It is important to avoid using soil that is too heavy or dense, as this can lead to waterlogged soil and root rot. A pH range of 6.0 to 6.5 is generally considered ideal for crotons.

Here is a simple list of some diseases and pests that croton plants may be susceptible to:

Diseases:

Pests:

It is important to keep an eye out for any of these issues and to take steps to control them if necessary. This may include treating the plant with a pesticide, removing infected plant parts, or improving the plant's growing conditions to help prevent future outbreaks.

  • Croton plants are toxic to both cats and dogs if ingested. The plants contain a number of toxic compounds, including saponins and glycosides, which can cause digestive upset and other symptoms in pets.

    Symptoms of croton plant poisoning in cats and dogs may include vomiting, diarrhea, drooling, loss of appetite, and depression. In severe cases, croton plant poisoning can lead to tremors, difficulty breathing, and other serious complications. It is important to keep croton plants out of reach of pets, particularly if you have cats or dogs that are prone to chewing on plants. If you suspect that your pet has ingested a croton plant, it is important to contact your veterinarian for treatment advice.

  • It is generally not common for deer to eat croton plants. Crotons are not a preferred food source for deer, and the plants' toxic compounds may make them unpalatable to the animals. However, it is always possible that deer may nibble on croton plants if other food sources are scarce or if the plants are easily accessible.

    If you are concerned about deer eating your croton plants, there are a number of deterrents you can use to protect your plants. These may include deer-resistant plants, fencing, netting, or deer repellents. It is also a good idea to keep an eye on your croton plants and take steps to prevent or mitigate any damage if it occurs.

  • Croton plants are not winter hardy in most parts of the world and do not die back every year. They are typically grown as perennial plants that return year after year if cared for properly. In areas with frost or freezing temperatures, crotons may need to be brought indoors or grown in containers that can be moved to a protected location. Crotons may also need to be repotted every few years to provide fresh soil and allow for growth.

  • Crotons are are typically grown as houseplants or in outdoor containers that can be brought inside during the winter months. In areas with warm, frost-free climates, croton plants may be grown as outdoor landscape plants, although they may need to be protected from direct sunlight and extreme heat.

    It is important to choose a location with well-draining soil and to provide the plants with regular watering and care to ensure that they thrive.
