~ Try air layering your houseplants have developed a “leggy look†through loss of their lower foliage, try air layering. This is a method of plant propaga- tion used on plants which do not of- fer much success when making rooted cuttings in the conventional way. Air layering is believed to have been developed centuries ago by the Chinese and it was no doubt inâ€" troduced into North America by the early settlers. Begin by making an upward cut inâ€" to the stem of the plant, leaving a sliver of four centimetres to six cen- timetres (about two inches) attached your houseplants Insert some wet sphagnum moss, and if available, treat with rooting hormone. Wrap the stem with wet Sphagnum mess (about a handful), surround with polyethylene film, and tie both ends with string. Be sure that the moss does not dry out. After the new roots have peneâ€" trated the moss ball (two to 10 weeks, depending on the species) and are visible on all sides, the rooted branch may be removed from the parent plant. The plastic should be removed and the rooted cutting placed in a pot of soil. To ensure success, cover the newly- potted cutting with plastic to prevent desiccation during its first week. Once the plant is established. remove the plastic. Air layering is common and useful for rooting ornamental indoor plants such as Benjamin figs, rubber plants, Dieffenbachia, and woody plants like azaleas.
