Q.Why Are There Different Types Of Cuttings?
Why are there softwood, hardwood, and semi-ripe cuttings? If you plant a semi-ripe or hardwood birch cutting, even though, most people plant them as softwood cuttings, would it still grow? Also, can evergreen trees be grown from any types of cuttings?

There are different types depending on the season you are propagating. Most softwood cuttings will root easily and they are propagated from new wood. Semi-soft wood cuttings can be taken in summer, and hardwood cuttings in winter or spring. The species of plant also determines which type of cutting will propagate best.
