If you’re lucky enough to live in the warm zones, plant your window-leaved plants outside in full sun where soil is gritty and well draining. For most gardeners, this species is limited to indoor growth. Choose a container that has excellent drainage and use a cactus mix or blend of half potting soil and half grit such as sand or perlite. The container should be shallow, as the root system on window leaved plants is not deep. Place the potted succulent in a bright area with some protection from the hottest rays of the day. Water weekly during the summer or once the top of the soil has dried out. In winter, suspend watering except once per month.

Haworthia has no notable pests or diseases. When soil is kept too moist, soil gnats are common. Fungal or rot issues also ensue in plants that are kept in high humidity areas, dimly lit rooms or overwatered. Overwatering is probably the biggest cause of failure to thrive with this easy to grow plant. Keep your plant where it is 70 to 90 F. (21-32 C.) for best growth. Fertilize once in fall and once in spring. Rarely, you may get one or two small white flowers if your Haworthia window plant is really happy. Repot every two to three years to keep the root system healthy and soil at its peak.
