Vertical Potato growing help
I tried growing potatoes vertically year, but failed miserably. lol. I am pretty sure I know what all I did wrong last year. But I have some questions about what I should do this year.
I will be using a bunch of black plastic crates that are about 18 or so inches wide by a little over 2 feet long, by about 10 inches deep. They stack, and I have cut out the bottoms.
I heard that there are certain varieties that will not work for an upright garden. What varieties will work?
When exactly do add the next level to the growing plants?
What kind of fillers should I use? Just compost? Or something different, like straw, mulch?
How high can you go with these?
I would greatly appreciate any advice anyone could give me! Thanks in advance!
