Care & Watering for a Croton Sunny Star

Water

• Over-watering is the biggest cause of crotons dying or failing to thrive. As a general rule, the plant requires no supplemental watering when planted outdoors, and soggy soil often results in leaf drop, rot or other fungal diseases. You should water occasionally in hot climates or during periods of extended dry weather. The best way to determine if the plant needs water is to check the appearance of the plant often and water whenever the leaves begin to look slightly wilted. As a general rule, apply 1 inch of water per week if it hasn't rained. Otherwise, don't water if the plant doesn't look wilted.

Fertilizer

• Although "Sunny Star" is a light feeder, it benefits from fertilizer applied in early spring and midsummer. Because the roots are sensitive and prone to burning when too much fertilizer is applied, an organic fertilizer is safest. For example, use decomposed cow manure, which can be applied generously on the soil around the plant without worry of burning the roots. Alternatively, use a fish emulsion fertilizer, which is safer for the roots because it releases nutrients into the soil slowly. Fish emulsion also provides micronutrients not always present in commercial fertilizers. Mix fish emulsion at a rate of 5 or 6 tablespoons mixed in 1 gallon of water or according to package instructions.

Mulch

• Croton "Sunny Star" benefits from a thick, 3- to 4-inch layer of organic mulch, such as chopped bark, pine needles, dry grass clippings or chopped oak leaves, which conserves moisture and keeps weeds in check. Also, organic mulch improves the soil as it decomposes. Keep the mulch at least 6 inches from the base of the plant, as mulch promotes moisture-related diseases.

Pests

• Pests aren't generally a problem for a healthy, well-maintained croton plants, but light infestations of spider mites, scale insects and aphids are easily treated by spraying the plant with insecticidal soap spray. Spray both sides of the leaves to ensure the pests are coated, as insecticidal soap spray kills pests only on contact. Reapply every four to seven days, using a mix of 2 teaspoons of commercial insecticidal soap spray in 1 quart of water. For heavy infestations, increase the mixture to as much as 2 1/2 tablespoons.
