Crotons are tropical plants with colorful, shiny foliage. Because of its tropical nature, the croton is injured in cold weather, so outdoor cultivation is limited to the warmer areas of the United States. Crotons have their best color when grown in dappled sunlight. As the plant ages, it tends to produce most of the foliage at the top, leaving the bottom portion bare and unattractive. Fortunately, crotons tolerate heavy pruning. Prune the croton in warm weather.
Cut off the top third of the croton plant. This will force new foliage to grow on the bottom of the stem.
Cut off another third of the plant when new foliage appears after the first pruning.
Pinch the tips of new growth to encourage the croton to produce new branches for a fuller appearance.
