Croton does best in fertile, well-drained, moist soil. They need bright, indirect light when grown indoors. Outdoors they thrive in partial shade, and in cool climates can tolerate full sun if kept moist (and are acclimated first when moved from inside). Higher light produces a more vibrant colour in the leaves and a more compact plant.
