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 lime free soil, 1 part coarse sand or perlite, 1 part peat Always use a pot with a hole.


Drench the soil and let it become moderately dry between waterings. If you use rainwater, be careful as it could be acidic. Use warm water.


Feed weekly with a lime free water soluble fertilizer diluted by half spring through fall.

Plant Pests:

Prone to spider mites. Always inspect any new plant for pests before introducing it to your home or greenhouse.


Seeds and stem cuttings with heel and bottom heat in the spring through summer. It is best to propagate any type of cuttings or seeds in a mixture of moist peat and perlite. Cover the pot and plant with a plastic bag secured by a rubber band to prevent the moisture from escaping. Place in indirect sunlight or under a fluorescent light. Repot in its regular mix after it has been growing for a while.

Gardening Tips & Care:

Mist occasionally with warm water (lime free to avoid leaf staining) and keep cool. Avoiding the midday sun in the summer is essential. Prune back and repot in the spring. If possible put outside for the summer in partial shade.
