If you do nothing and your strawberries are growing in a raised border, chances are the runners will find a cosy spot elsewhere and root there. No work involved :-)
In fact this may happen even if your strawberries grow in a container and you locate your container right next to the spot where you want them to grow in. I have placed my strawberry containers right next to a raised border and voila the strawberries have now successfully migrated to a raised border. This saved work as I don't have to dig holes - which would have been the case if I had transplanted them from a pot.
The other technique I have used is to fill a small pot with a dirt and then press the tip of the strawberry runner which is growing the new leaves against the pot. For this I used small sticks as I didn't have any wire at hand. Most bloggers on the internet recommend wire. But in truth you can use just about anything that is at hand and can do the job - use your imagination.
After the new strawberry plant roots into the pot you can cut the runner and then transplant the strawberry to a new container or another border - or why not offer it as a gift?
In summary - growing strawberries from runners is the easiest job in the world and can save you a lot of money in new plants.
