Grow crotons and you'll experience a vibrant explosion of colors thanks to the plant's colorful foliage, which comes in an array of reds, greens and yellows. Crotons can grow in USDA hardiness zones 9b through 11 and can serve as garden accent pieces or as hedge-like shrubbery. Provide your croton plants with sufficient water--they are xeriscape friendly, requiring little water--so you can enjoy them for years to come.
Water croton plants that are grown directly in the ground with a fourth of an inch of water once every two days, or as needed in your local climate. Croton plants thrive on little water. Use the plant's foliage as an indicator; slight wilting means you should water more often.
Increase waterings to once a day for croton plants that are grown in pots, as the pots' contained environment is not capable of retaining water as well as a soil bed.
Water the croton's foliage if it's grown indoors. Croton plants require a relatively high amount of air humidity. Combat dry indoor air by misting all of the plant's foliage with a water spray bottle once a day.
