My Pulasan grows very slow...1 grafted tree is 70 cm tall and 2 years old....the other one is 60 cm tall and 1 year old.
They die back sometimes and also get dead leavetips after that they drop the leaves and make new ones.
My rambutan grows at the same speed.
Also my pulasan's can not be in the front garden where the sun is all day long. Many other pulasan's died there so now i keep them in sun untill 1 pm. Mine get citywater , i think they prefer rainwater.
