Kept well for 2 weeks at 60º F (15.56º C). A decoction of the roots is taken as a febrifuge. Early in season (mid-July).

Even if you live in the appropriate USDA zone for growing the rambutan tree, keep in mind that Mother Nature is fickle and you need to be prepared to protect the tree from a sudden dip in temperature. A serious disease, stem canker, caused by Fomes lignosus in the Philippines and Ophioceras sp. Few pests or diseases have been reported by rambutan growers. Air-layering may at first appear successful, but many air-layers die after being transplanted into 5-gal containers, or, later, in the field, long after separation from the mother tree.
