Propagation by Cutting

Herbaceous cuttings Stem Cuttings Leaf Cutting Leaf Bud Cutting Root Cutting

Herbaceous stem cutting-with tip

Leaf cutting

Root cuttings

Factors that affect rooting Time of year Age of stock plant Physical condition of stock Plant species or cultivar

Conditions that promote rooting Temperature Water Light/dark Rooting hormone –Auxin promotes rooting –IBA Indole-3-butyric acid –IAA is the natural auxin but unstable

Rooting Media Clean soil mix Vermiculite Sand Water Forsythe Pot

Woody cuttings Tip Simple or straight Heel Mallet

Simple, straight cutting heelMallet

Woody Cuttings Woody cutting take longer to root Some are cut in fall and kept cold all winter Usually benefit from a strong rooting hormone: 8000ppm IBA
