William Moss: Gardening is a four season sport. Winter time does not mean break time for gardeners. In fact, many things are best done during the coldest months.
One of those tasks is pruning your berry bushes. You want to prune them in winter time, but you can see the structure and it's pretty easy to get to. Plus, everything is dormant, so you are not going to do too much damage during the dormant season.
You are going to need pruners and loppers, also some very tough gloves. What I want is I want a lot of berries, but I want the growth to be more controlled so I can get larger berries that are going to be sweeter. I am going to start taking out all of this light growth.
Now, it's just a matter of cleaning up the other sides. But, you can look for the obvious things when you have branches that are crossing, you don't want the branches occupying the same space.
Most berry bushes won't be trained along a fencing or along a flat surface, most times, they will be growing out in the open like this. And what you're trying to do is you want to keep encouraging new growth. If I allow the older canes to grow, a lot of them will put their berries down into the interiors, and it would be hard for me to get to them.
So now what I am left with is a lot of straight branches; it's open and airy. Lots of sunlight will be able to get down into this bush, and I have an easier time picking the fruits that I wouldn't before. Open them up, get rid of some of that light growth, so you would have bigger sweeter berries coming summer. Get out and grow!
