Cutting raspberries back?
I know the conventional wisdom is to cut the raspberry cane back in the autumn to about a foot in length. However, I normally leave a few old cane of about 3 feat as I find that these tend to sprout and flower earlier, which seems to give me an earlier harvest. I then tend to get a second flush from the new shoots from the root stock later in the summer. I'm just wondering whether doing this diminishes my second flush of fruit from the new shoots due to the older cane blocking out the light?
