Layering and Air Layering: Plant Propagation Methods

Climbers and trailers like Hedera, Jasminum, and Philodendron can be easily propagated similarly to plantlets. Before starting, water the parent plant and wait half an hour to ensure stems are healthy and not wilting. Choose a long, vigorous stem, bend near a leaf joint, and gently pin it into a separate pot of compost using a small U-shaped wire. Firm the shoot at the pinned point and water. Once new shoots appear from the pinned point, the plant has rooted and can be safely cut from the main plant. Use a knife or sharp scissors to carefully detach.

Air Layering

Air layering is most useful when plants like Ficus elastica lose lower leaves. Also suitable for Monstera and Dracaena. It creates a new root system higher up where leaves remain. Once roots form, the new plant is cut off the top of the old one and replanted.

Strip a small bark section from the stem or make an upward slanting cut where you want new roots. Use a matchstick to keep cut surfaces open and coat with hormone rooting powder to encourage rapid root formation. Cut the bottom from a polythene bag, place the tube over the stem. Tie bag 3-5 cm (1-2in) below the cut, fill with damp sphagnum moss pushed firmly but not solidly around the cut stem, then tie again above the cut. Don't damage the stem by tying too tightly.

Keep the parent plant's compost moist but not too wet. Roots may take several months to form. Check occasionally by carefully untying the bag. Once roots form, cut below the bag and pot the new plant into fresh compost. Avoid damaging fragile new roots or restricting growth with too small a container. Stake for support until established.
