A local team of botanists, conservationists and volunteers commenced an intensive programme of hand pollination and seed collection of the remaining cultivated tree, while protecting it from insects that may cross-pollinate with nearby false gumwoods.

F2 hybrids, the result of self or cross pollination of F1s, lack the consistency of F1s, though they may retain some desirable traits and can be produced more cheaply, because hand pollination or other interventions are not required.

Poor fruit production has been reported in Florida because there are few natural pollinators ( honeybees have a difficult time penetrating the tightly closed female flowers ); however, hand pollination with a natural fiber brush is effective in increasing yield.

The volume is a treasure-house of information, starting with historical profiles of the plants and going on to botanical classification, flower structure and pollination method, isolation distances, caging and hand pollination techniques, and ways of harvesting, drying, cleaning and storing seeds.
