How to Fertilize Croton


Crotons (Codiaeum variegatum) are colorful shrubs that can grow to 6 feet in height and grow outdoors only in warm areas. They thrive indoors as a potted houseplant in a sunny, warm location. The best time to fertilize croton is in the spring, before the plant puts forth new growth.

Fertilize Croton in the Garden

Step 1

Rake back any mulch in the croton bed, then rake to loosen the top inch of soil.

Step 2

Sprinkle the fertilizer on the soil around the croton plants, at the rate suggested on the package. Use the rake to lightly spread the fertilizer out about 1 foot from the plants.

Step 3

Water the croton bed until the soil is saturated. This will help to activate the fertilizer and help it work its way to the croton's roots.

Fertilize Croton in Pots

Step 1

Remove any mulch in the pot. Use the hand cultivator to scratch the surface of the soil to loosen it.

Step 2

Sprinkle the fertilizer, according to the rate suggested on the package, onto the soil and use the cultivator to rake it into the top inch of soil.

Step 3

Water the croton until water runs from the bottom of the pot.
