How to take care of Crotons :

Light: Crotons love bright light and thrive in it, and in fact require it to produce those stunning multicoloured leaves. But they also don’t like to be burned by the sun. If you are in a very hot or dry environment where the sun is oppressive, it is a good idea to put some shade cloth up so that they can absorb less of the direct UV rays during the heat of the day. If grown indoors, they do prefer brighter spots near windows or under grow lights.
Water: Like most tropical plants, crotons like humidity. It’s often beneficial to set your croton plant on top of a rock tray with a little water in it to help keep the moisture up around the plant. If you’re raising yours as a hanging plant, occasional misting will also help increase the ambient humidity. However, they also don’t like to have wet feet, so it’s best to only water them when the top half-inch to an inch of soil is dry to the touch. When you do water them, water until it starts to come out of the bottom of the container, then wait until the soil dries out again before rewatering. Crotons can be susceptible to over-watering. If you find that your croton’s leaves are wilting, that may be a sign of too much water. If the lower leaves are drying out or falling off, that’s a sign of under-watering and your plant’s thirsty.
Soil: Crotons prefer well-draining soil with lots of organic material. Most good potting soils are fine, and an ideal range for the soil pH level is between 4.5-6.5 pH. High-pH rock soils are not advisable, as are soils that are very calcium-rich.
Fertilizer: A popular fertilizer type for crotons is an 8-2-10 mix, as they tend to like a lot of potassium. Most often, they’re fed once in the early spring (Feb-March), and then again in the late spring (May), giving them a good slow-release acidic fertilizer that will feed them throughout the summer months. Younger plants may require a third feeding somewhere in mid-July. Don’t fertilize in the fall, as the leaves need to mature and harden off before winter.
