@ Pam, no dont worry about moving them yet, plants take a couple of years to mature so they should just be ramping up to give you a bumper crop. If congestion, pull a few up to give space, pinch out runners or encourage them to root in 3" pots so they can be easily moved and help your over crowding problem
@Scott - I only ever get 1 year out of my potted strawbs as the Vine weevil always get them, soil always works so much better for me.
@ Benjamin9876. stawberries are pretty easy to grow. they like a good soil, with lots af compost and manure and sume sunshine. i also give mine the out feed during the summer ust as the fruit begin to form.
The plants will last for 4 or 5 years before they need replacing and they will have 100's of babies before they are done. The babies (on shoots called runners) can be potted up to give you more plants. i think I had about 3 plants 5 or 6 years ago, i now have a whole patch
