I thought I would keep the forum informed of our first trials at macro propagation.
We have built two wooden boxes in 2m x 1m
and lined the bottom and sides with a sheet of black 300 micron LDPE, filled the box with 30 kgs of sawdust and positioned about 30 pared corms of Thai variety Kluai Hom (Gros Michel)
We started this 8 days ago. The sawdust is being kept nice and damp, initially given three watering cans H2O and this is the dosage we are giving every three days now. The boxes are covered with clear 150 micron PE sheet, tied down with string.
Yesterday, I checked the corms. It's nice and hot and damp in the boxes, outside afternoon temperature is 40C right now. A few had dominant buds growing which I promptly killed. Some have already developped new roots which are 5cm long and showing up on the surface of the sawdust.
We have built another two boxes now and will start the same process with Kluai Namwah as soon as the corms become available.
For both varieties, we are using large corms, about 15cm in diameter.
I'll will keep you updated on developments.
