Soil Type: A GOOD general purpose potting soil (a soil that retains water yet drains well) will suffice. Check purchased soil to see that it is well aerated and add sand or perlite and peat moss if it seems to pack too tightly. Give the plants a chance to settle in before going back to whatever fertilization program has been successful for you. If you want to mix your own take: 1 part garden soil, 1 part coarse sand or perlite, 1 part moist peat or humus (leaf mold) and a light dusting of lime. Always use a pot with a hole.
Watering: Keep the soil evenly moist and if you use rainwater, be careful as it could be acidic. Use warm water.
Fertilizer: Feed every two weeks during the growing season with a water soluble fertilizer.
Plant Pests: Prone to spider mites. Always inspect any new plant for pests before introducing it to your home or greenhouse.
Propagation: Offsets in the spring. After dividing offsets, pot in the plant's regular potting mix.
