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: 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.
Fertilizer: Feed every two weeks with a water soluble, lime free fertilizer during the spring and summer.
Plant Pests: Prone to whitefly, mealy bugs, aphids, scale and spider mites. Always inspect any new plant for pests before introducing it to your home or greenhouse.
Propagation: Stem cuttings, suckers, air-layering at anytime. Summer It is best to propagate any type of cuttings or suckers 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. To air-layer a plant, take a sharp knife and cut half way through the stem about a foot down from the top. Put a toothpick in the wound sideways, wrap wet sphagnum moss and a plastic bag around the wound secured by either rubber bands or tape. When roots form, cut off below the roots and plant
