Crotons are leafy perennial tropical shrubs. They have bright colorful leaves that range from dusky red to bright orange, yellow and green all on the same plant. Crotons will not grow outside in temperate climates but they do make great houseplants. Pot them up in bigger pots as the plants mature and keep them inside on all but the hottest summer days to enjoy these exotic members of the tropical jungle all year-round.
Fill a planting pot half full with a mixture of peat moss, coarse sand and potting soil in equal parts. The peat moss and coarse sand will keep the soil from becoming heavy and compacted.
Take the pot your croton is currently planted in and turn it on its side. Grasp the base of the trunk and gently wiggle the plant back and forth until is comes loose.
Set the croton in the new pot so that the root ball is resting on the soil in the bottom of the pot. The base of the stem should be 1 to 2 inches lower then the rim of the pot. Fill in or remove soil under the root ball until the base of the stem is at the correct height.
Fill in around the root ball with your soil mixture. Add a few handfuls at a time and pat it down as you go. The top of the soil should be a quarter to a half inch above the top of the root ball.
Water your croton thoroughly. When the soil is sufficiently wet, you will see water seeping out from the drainage hole in the bottom. Allow the pot to drain and then set it in a window where it will get filtered light throughout the day.
