yep, one plant produces many. Pick sll berries, it will encourage more. Bonemeal is a good organic Phosphorous source, and strawberries like lots of P. Maximum production will be in the second or third year, read up meanwhile on seperating new runners, which will be more productive, but don't be afraid to experiment or just leave them alone, you will have lots of strawberries soon. As an organic grower, I would put on bonemeal and horse, cow, or rabbit manure, but short of gtting a soil test, thre's some guesswork involved.
