T or F: Hardwood cuttings are taken in the winter when the wood is dormant.
True
T or F: Root cuttings are always taken vertically.
False, you may not know which direction the roots were cut from that is why cuttings are typically placed horizontal in the potting medium.
Tor F: Wounding the bark of a hardwood cutting will limit its ability to root.
F, by wounding the base of hardwood cuttings, cambium cell division and differentiation is stimulated which encourages adventitious root formation. This is usually not done on easy-to-root species but can enhance rooting in difficult to root species.
T or F: Auxins are usually not necessary for rooting herbaceous cuttings.
True, auxin is produced in the leaves so exogenous auxin treatment is not usually necessary. However, auxin treatment will improve uniformity of rooting and is occasionally used when production schedule is a concern.
T or F: Herbaceous perennials can be propagated by seed.
True
T or F: Perennial plants may be both herbaceous and woody.
True
Tor F: Bottom heat and cool air temperature are ideal environmental conditions for hardwood cuttings.
True
