avocoda growing in chaing mai 

having difficulty in pollination? never experienced this before in the states. any suggestions. also where can i visit a plantation or research center in north? thanks

How is the local bee population. What crop size are you talking about?

 

Also be interested in fruit getting pea or grape sized and dropping off. Have heard it can be from lack of water... But not sure when in the life cycle.

On average, about 283 litres of applied water are required to produce a kilogram of avocados.
