(ii) Semi-hardwood cuttings
  (a) Stem is selected from partially mature wood 
  (b) Season : Late spring to late smmer.
  (c) 3"--6" long.
e.g. Citrus, olive ,etc.
(iii) Softwood cuttings
 (a) New and soft stem.
 (b) Season : Spring to early summer.
 (c) 3"--5" long .
 e.g. Magnolia 
(iv) Herbaceous cuttings.
  (a) Stem from non-woody plant .
  (b) All seasons i. e.any time in the year .
