Step 1

Place your potted croton petra in an area of your home that receives full sun and minimal shade. Croton petra thrives in well-lit areas, but do not place the plant in direct sunlight.

Step 2

Maintain a moderate temperature between 60 and 75 degrees Fahrenheit in the room where you display your croton petra. Temperatures higher than 80 degrees Fahrenheit may cause the croton petra to wilt and dry out.


Step 3

Allow the soil to dry out before watering. When watering, do not over-water, as it will cause the leaves to yellow and possibly rot. Water slowly, allowing the moisture to soak into the soil, and stop before a pool forms on the top of the soil.

Step 4

Fertilize once a month with a low-nitrogen, water-soluble fertilizer. Do not fertilize during the winter months.

Step 5

Promote bushiness in mature croton petra plants by pruning the plant back where leaf joints appear.
