My neighbor gave me some really nice raspberry bushes a few years ago, but because of thorns, our neighbors to the west of us killed my plants. Fern kindly game me more and I relocated them where little fingers won't get poked.
So here is what you do to keep your plants happy and healthy:
This will work with Raspberries, Blackberries and Currants. Keep in mind that they take more space, but they are super easy to grow. Once you harvest be sure to remove and old drying canes this will make them happy and healthy. Also pinch back any tips of new growth 3-4 feet to encourage branching. once the fruit has formed, you may want to net your plants to keep the birds from enjoying them more then you do!
