Mulberry Propagation

I stem cut and plant them into recycled bottles. They seem to grow VERY WELL in these recycled bottles. Basically I cut 500ml water bottle to about half and then invert the cap side upside down. This will help to drain off the water from the soil to the bottom. The bottom collects water but it doesn't attract mosquito as it is concealed! What a wonderful idea on recycling!! They grow better than if I were to grow them in a normal pot! So strange right!
