This was one of those questions that bothered me and about which I could find little information.
The tips of Martijn De Voedingboss always make me a little happy. I got to know him during an onculeting course.
But here he explains in great detail how he proceeded. What I like so much is that he experiments himself and sees what works and what doesn’t work. Remember every soil is different and nature is not always predictable.
The result with him is clear. Enjoy watching.
