I've got a piece of land, say 1/4 acre, that I would like to plant with raspberries mainly, with blackberries and some other varieties. It's sitting directly on top of a drain field, so should be fairly fertile. The problem with this area is that it's always getting overrun by weeds. Not little ones either. It becomes a mass of foliage and thorns so thick you can't even walk into it. That's part of why I want to plant there, to choke the weeds out. The land is currently cleared except for some small trees that will be gone soon. I know it's full of weed seeds that will sprout as soon as the weather gets warm. (I'm in zone 8a). I'm prepared to deal them as I must, however aggressively I have to. (Not using herbicides, only mechanical means). What I want to know is, what is best way to plant raspberries in this quantity? I'd like to do long rows, but how far apart? I know, that will depend on the varieties, but maybe just some general guidelines? This is going to be quite expensive, so I mainly want to ensure that the plants survive. And, I'm more concerned with plant growth than berry production. Any ideas?
