Every time the new shoots are drawn to a length of about 30cm, they are cored or chopped.

2, thinning flowers and fruits:

Guava is easy to blossom and has a high fruit setting rate. In order to promote fruit growth, achieve the goal of big fruit, high yield and high quality, and improve economic benefits, it is necessary to sparse flowers and fruits. Flowers become thinner when they are in full bloom, and fruits generally become thinner after flowers wither, when young fruits grow to the size of fingers. Each branch only needs 1-2 fruits, leaving 6 pairs of leaves.
