questions: asking about air layering of litchi 
 answers: air-layering or 'gootee' is widely accepted method of propagation in india. in this method a healthy and
vigorous, upright twig of about one year old and 2.5 to 4 cm in diameter is selected. a circular strip of
bark about 2 cm wide just below a bud is completely removed from the selected twig. care should be
taken to remove all the cambium tissue surrounding the white central wood while removing the bark.
moist sphagnum moss is packed around this portion and tied with polyethylene sheet, which prevents
the loss of moisture. in about 6 weeks, when the roots are visible through the polythene wrap, the
rooted branch is detached from the parent plant and potted in the nursery. top of the branch is cut back
to maintain a proper ratio of leaves: roots.
