I am still receiving requests for Calamansi plants propagated by air-layering from my eight year old Calamansi tree or some Singaporeans call it “sng kum” others call it “keat lah” and in Malay, it is known as limau kasturi. Unfortunately I cannot fulfill all the requests as I usually do about half a dozen of cuttings each year. The reason is I do not like to over-stressed the mother-plant. I do have seeds to give away, The problem with growing fruit trees from seeds is that it may take very long to bear fruits - some times more than three to five years - and there is no guarantee that the fruits will taste same as the one from which you got the seeds.
Air-layering is one method of propagating a fruit tree from an existing one, which will bear fruits sooner, and the fruits will taste same as the mother-plant.
