Rooting
Rooting is the formation and development of roots. The word can describe a germinating mango seed, new roots after transplanting, or attempts to propagate a cutting, but those are different processes with different success rates. Mango is commonly multiplied by grafting onto seedling rootstocks because ordinary cuttings are not reliably easy to root. New leaf growth alone is not proof that a detached cutting has a working root system. Evaluate roots and sustained growth before treating it as established.
