Layering is a way to grow new plants from existing plants without having to take any cuttings. In a nutshell, bury part of a stem or branch in the soil and new roots and shoots will form. This method is often more successful than propagating from cuttings, because the new plant can get water and food from the stock plant. Once the new plant is established, it can be moved to another spot in the garden.

Layering is a quick method of propagation made simple with the purchase of electrician’s safety staples. These hardware items are quick and easy to use. Find a stem for propagation, remove a few leaves where the stem will be submerged into the soil, then secure the stem under the soil with the staple. When the cutting has rooted and is ready for transplant, the coated top will help you find your stem. You can then reuse the staple until Hawaii’s rust gets the best of it. As of this date, 100 grey ones at Home Depot cost less than $3. I bought these orange ones at Yamashiro’s in Kaneohe.
