Many of us ask when to do inoculation??
Whenever the tree trunk reaches 4″ at breast high diameter (BHD), it is considered mature enough to perform inoculation regardless of any method available nowadays. Could it be liquid inoculation or Bamboo stick from Witsawa (Thailand).
In my farm , i have started to induce the trees when BHD is 3″. The inducement of Bamboo sticks is carried out in stages in order not to kill the trees at one time. Keep the drilling holes at a distance say 12″ apart, by next year we drill another hole 4″ from the first one, and the following year another hole 4″ from the second one. Repeat this pattern for the entire tree. By the time you come to harvest you will have different grades of products.
Doing this way will shorten the waiting time, while awaiting for the trees to grow bigger.
