Thanks for the video it is interesting, you know. He has some very big, you know, and deep raised beds.
One of his other videos state that the depth of his raised beds ranges from 12 to 33 inches deep. That is because his land slopes down to the street, and he wanted to keep the beds level...
His beds are so deep that I don’t know how he tends them. Of course, he’s young and athletic, so it’s probably not a problem.
With a name like ‘John Koller’, I’ll bet his mom is Asian! Probably Japanese, or Philipino. I love his videos. Did you see the one about how he keeps people from stealing his food. It’s priceless!
