The first year I’m getting pears. I expect they will grow quite a lot yet, they only flowered a month ago. I’ve waited 8 years to see fruit, the tree is probably 15ft high. If we can grow apples, pears, cherries, plums and apricots up here, you should do alright investing in some fruit trees.
On the other end of the scale, anyone hear of haskap / honeyberry? The earliest producing berry around, comparable to blueberry in taste. They are thriving on poor soil in severe climate up on my land.
