| CACTACEAE |
 |
| Various genera |
Common names: Cacti
Light needs: High light, direct sun.
Best temperatures: Average room temperature most of the year with cooler conditions in winter 40-65ºF (4.5-18ºC).
Water and humidity needs: Water thoroughly and wait until the soil surface is dry before watering again. Decrease water from May through December; give almost no water in the winter. Low humidity is fine for cacti.
Growing guidelines: Keep potbound in well-drained clay pots of all-purpose mix with added sand. Fertilize once a year in spring. Provide a cool, dry period in winter.
Common problems: If a cool, dry period is not provided in the winter, the plant may produce weak, spindly growth. Overwatering may lead to wilting and root rot.
Propagation: Stem/leaf cuttings, offsets, and seeds. Grafting is also possible with most cactus.
Currently in Greenhouse: Yes
