How to take care Crotons :
Light : Crotons love bright light and thrive in it, and in fact require it to produce those stunning multicolored leaves. But they also dont 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. Its 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 youre raising yours as a hanging plant, occasional misting will also help increase the ambient humidity. However, they also dont like to have wet feet, so its 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 crotons leaves are wilting, that may be a sign of too much water. If the lower leaves are drying out or falling off, thats a sign of under-watering and your plants thirsty.
Soil : Crotons prefer a 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, theyre 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 mid-July. Dont fertilize in the fall, as the leaves need to mature and harden off before winter.
