Detailed explanation-1: -i) Hardwood cuttings: Cutting from mature and lignified stem of shrubs and trees are called as hardwood cuttings. Hardwood cuttings are prepared during dormant season, usually from one-year-old shoots of previous season’s growth (Plate 5.1).

Detailed explanation-2: -For fall plantings, collect cuttings in the early fall of the same year, after plants have gone dormant (at least 50% of the leaves have changed color or have dropped).

Detailed explanation-3: -A range of herbaceous plants can be propagated from root cuttings. These include Acanthus, Anemone hupehensis, A. x hybrida, Echinops, Papaver orientale (oriental poppy), Phlox, Primula denticulata and Verbascum.

Detailed explanation-4: -Root Cuttings 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.
