We are low on ground space, so we've been reading up on vertical gardening and came across a book about growing potatoes in wooden towers.
Anyone have experience with this?
The idea is that as the potato plant grows, you hill the soil up around the stem and the plant produces more and more spuds in the root system. As you add soil to the top, you also add higher sides to your potato box, so your plant elongates in the soil and the wooden sides move up with it and the soil level.
I know that having the soil properly aerated is key and that you also have to grow a late season potato variety to be successful. In theory you're supposed to be able to get many pounds of potatoes from one wooden tower.
I watched a bunch of YouTube videos of people harvesting their vertical potato crops and all were busts and only got around 8 spuds total. Pretty disappointing for all the work to buy or build a wooden tower/container. Some people realize they had too compacted soil and also not the late season varieties.
Have any of you had success growing potatoes in wooden towers using correct soil and potato varieties?
