Okay, more about the potato towers. With this heat we've had, they taters started dying. The neighbor who planted the same seed potatoes in a bed, which gets a bit less sun, had live taters still. We harvested one of the towers tonight. What I noticed, was that we had not mixed the soil and peat properly, and the peat parts were really dry. There were a lot of potatoes, but they were very small. Had we been able to keep the tower alive, I think it would of yielded easily 5-6 times more than it did, now it only held about 4 kg. The neighbor harvested some of his potatoes yesterday too, and his were a lot bigger, on average maybe 4-5 times bigger. The biggest difference between our growing, was that he planted in uniform soil, wile we planted in badly mixed soil. Now we've learned another lesson for next year. I just thought I'd share this in case someone decides to try the towers.
