Root Cuttings . Cuttings taken from roots may also be used but only a few species can be propagated this way. Cuttings are taken when the plant is dormant and the roots contain the most stored energy. Each root produces two to three new stems and each stem then produces its own roots. The original root cutting disintegrates. Propagation Basics

Place stem and leaf cuttings in bright, indirect light. Root cuttings can be kept in the dark until new shoots appear. Stems Cuttings Numerous plant species are propagated by stem cut-tings. Most can be taken throughout summer and fall, but stem cuttings of some woody plants root better if taken in the fall or in the dormant season. Success with

Root cuttings usually are taken from 2- to 3-year-old plants during their dormant season, when they have a large carbohydrate supply. Root cuttings of some species produce new shoots, which then form their own root systems.
A cutting is a section of plant such as a modified stem, leaf, or root used for vegetative propagation that forms either adventitious shoots, adventitious roots (stem and single node cuttings), or both (root and leaf cuttings).
Typically, cuttings should be stuck 1⁄2 to 3⁄4 inch(1.3 to 1.9 cm) deep into a rooting substrate. Cuttings that are stuck too shallow are prone to lodging. Cuttings stuck too deep may have root initiation and development hampered by lack of oxygen in space that is constantly filled with water.
