During summer season keep the plants in shaded area and during winter season plants can withstand direct/indirect light.
During summer season or when the temperature is above 45°C place the plant in shaded area. During winter season or the when the temperature is below 45°C the plants can be directly placed in direct/indirect sunlight.

Croton "Petra" (Codiaeum variegatum var. pictum "Petra") adds bright color to the garden in the form of long, leathery leaves with splashes of red, orange, pink, yellow and green. Use these evergreen shrubs as hedges, as specimen plants or in shrub borders. They don't need routine pruning, and left to their own devices they grow to a height of 7 to 10 feet with a spread of 4 to 6 feet. "Petra" is hardy in U.S. Department of Agriculture plant hardiness zones 9b through 11.
Select a site with full sun or morning sun and afternoon shade. "Petra" needs moist but well-drained soil that is rich in organic matter.
Prepare the garden bed by loosening the soil and working in 1/2 pound of 15-5-10 slow-release fertilizer. Dig the fertilizer into the top 6 to 8 inches of soil. Work in a 2- to 3-inch layer of compost if the soil isn't particularly rich or doesn't manage moisture well.
Plant "Petra" in the bed at the depth at which it grew in the container. The soil line on the stem should be even with the surrounding soil. Press down on the soil as you fill in the hole to remove air pockets. Space the shrubs 4 to 5 feet apart for hedges, and at least 6 feet apart in shrub borders.
Water slowly and deeply to saturate the soil around the roots. If the soil settles, add additional soil to make it level again.
Add 2 to 3 inches of organic mulch around the base of the shrub to help the soil hold moisture.
Water established plants to provide 1 inch of water per week in the absence of rain. Reduce watering in winter to give the plants a rest period, but don't allow the soil to dry out completely.
Fertilized established plants with a 2- to 3-inch layer of compost or 1/2 pound of 15-5-10 slow-release fertilizer per 100 square feet of garden bed. Work the fertilizer into the top 1 to 2 inches of soil, taking care not to damage the plant's roots.
