Layering is best done in spring and summer when plants are actively growing.
For outdoor trees and shrubs, choose a flexible stem that’s close to the ground and is long enough for its middle section to be buried in the soil.
For indoor plants, choose a stem that can be positioned or bent so it can touch a pot filled with potting mix. A seed raising mix like Yates Specialty Potting Mix Cuttings & Seeds is ideal as its fine texture helps create good contact with the stem.
Not all layering attempts will work, so, the more stems you use, the greater the chance of success.
For plants with thick stems, using a clean razor blade or sharp knife, make a shallow cut a few centimetres long on the underside of the middle of the stem where it will be touching the soil or seed raising mix. Ideally the cut should be made over a node, which is the bump on the stem where leaves would normally grow from. Remove any leaves from around the cut area.
Make sure you don’t cut through more than a third of the diameter of the stem. Cutting the stem promotes a wound response and helps adventitious roots to form, as auxin (a plant hormone that promotes root development) accumulates near the cut. To further promote root development, dip the cut into some or Yates Clonex Rooting Hormone Gel - Purple for hard and semi-hardwood cuttings
For indoor plants with thin stems like chain of hearts and ivy, there is no need to cut or wound the stem, as these plants naturally have adventitious roots.
Bend the stem towards the soil or pot of seed raising mix and bury the wounded section in the ground or seed raising mix. It can help to weigh down the soil over the stem with a brick. For indoor plants, bend a paperclip into a U-shape and press that down and over the stem to secure it into the seed raising mix.
Keep the soil or seed raising mix moist, but not wet, and roots should develop over the coming months.
Once a small root system has developed (you can check by gently scraping away some of the soil or potting mix), cut the stem from the parent plant and pot it up into a small pot with premium potting mix like Yates Premium Potting Mix with Dynamic Lifter. It’s important to keep the potting mix moist while the new plant establishes.
