Cactus and succulents make excellent house plants. They adapt naturally to dry, warm temperatures (common indoors) and withstand poor care for days, even weeks at a time. They almost always arouse interest with their sculptural form and the variety of leaf sizes, shapes, and arrangements often combined with striking color patterns.

Grown in attractive pots, dish gardens, and terrariums, they can be displayed in windows or under bright lights, or in hanging baskets. they can be dramatically silhouetted against a light-colored wall or softly illuminated with well-placed spotlights.

What Cactus and Succulents Need Indoors

  • Light: Bright light is necessary. Grow cactus and succulents in a window when possible; east and south-facing sills provide the best location to keep them healthy. Avoid placing them right next to window glass in summer; they can burn.
  • Temperature: Average home temperatures are best about 65°F (18°C) during the day and 10-15° cooler at night, always warmer than 45°F (7.2°C).
  • Moisture and Air Circulation: Water to moisten the soil then let the soil nearly dry out before watering again. Average indoor humidity is sually sufficient. A well-venitlated room is important; plants want clean well-circulated air.
  • Rest Period: Once a year–usually in winter–cacti and succulents enter a dormant period. Plants need some light but cooler temperatures (about 50°F ) to rest. During the rest period the soil should be kept barely moist.
