Hmmm this my my first year with strawbs too but I can make some observations
I had quite a good crop even though it was the first year! I had bastard trenched the ground beforehand, maybe that explains it? (buried organic waste under the new beds). When runners appear if you want fruit, chop them off!!! Or just keep a couple as runner producers and chop the fruit off those as the flowers appear!
I would say that you could plant strawberries with other things, but they do get quite big so make sure they have enough room.
As mine are in the ground, I don't know about watering pots but I know they like water and feeding when fruiting. didn't have to water ANYTHING this year. except when sowing seeds....
What type of strawberry are you growing?
