Bright filtered light helps maintain leaf colour. The plant prefers a temperature of between 20 to 30 °C. 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. Keep compost moist throughout the growing season. Low winter temperatures will check growth and watering can then be reduced; allow the plant to partly dry out before watering.
Feed every two weeks with a water soluble, lime free fertilizer during the spring and summer.
