In organic growing programs you feed the soil first the plant second. Your goal is to create the ideal soil environment, one that is biologically active, for the particular plant type you are growing / maintaining.
You do not need to have a lot of land to grow commercial quantities of lychees. Many people with only one or two mature trees can make a nice extra income by picking and selling their fruit locally or to fruit packers.
An air layer is a way to create a new mature lychee tree from the branch of an existing one while it is still attached to the parent tree. Since this process occurs in the foliar branches, suspended in air above the ground, it is referred to as “air” layering. The resulting tree is the same species and cultivar as the parent, rather than a hybrid with questionable fruit and growing characteristics.
The soil food web is the community of organisms living all or part of their lives in the soil. A food web diagram shows a series of conversions (represented by arrows) of energy and nutrients as one organism eats another.
