How to Propagate Guava
Guava is a pulpy, sweet, and juicy fruit that is high in vitamin C and fiber, and helps prevent cancer and diabetes. While the simplest way of propagating guava trees is from seed, agriculturists agree that guava trees grown from seed rarely retain all the desirable characteristics of the parent plant. As a result, alternative methods such as root cuttings and budding are recommended.
The use of root suckers is probably the oldest method of asexually propagating guava. Root suckers are induced by severing roots to a few feet from the base of the plants and these are transferred when roots and shoots are established.
Root cutting is done by cutting about 12-20 cm long parts of any butt very small or very large roots. These can be induced to sprout and form new plants provided it is placed in a suitable medium in a well-drained propagating bed. Both the use of root suckers and root cuttings are relatively slow methods of propagating guava.
Budding is also an efficient method for propagation. Both the patch bud and forkert techniques are recommended onto seedling rootstock. The diameter of seedling stock and budwood should be from 15-25 mm. Budwood should be mature, bark no longer green. Condition the budwood by cutting off the leaves of selected branches 10-14 days before removing the branches for budwood. During this period the buds become more enlarged and grow more readily after budding.
Lastly, stem cuttings made from the young wood at the end of the branches can also be used to propagate guava. These are rooted in sandy loam soil in propagating bed in a nursery house or shed. Guava stem cuttings treated with Indole Butyric Acid (IBA) or Napthalene Acetic Acid (NAA) proved to be successful for rooting and produce numerous and vigorous roots.
