Strawberries in an Earthbox

I have had sucess growing strawberries by covering the part of the runner closest to the new plant shallowly with soil and anchoring it there either with a bent piece of wire or a small brick or rock. After the new plant has taken root, you can then cut the runner from the mother plant. If the mother plant is in a container I would place a pot next to it for the new runner to grow in. I have been told to only use first and second year runners because strawberries are usually infected with viruses by the third year, but any runners will take strength from the mother plant and reduce yields. :)
