Sad strawberries

Hello All
We have wild strawberries in a strawberry container (fabric) which did well last year, much to the delight of the birds.
This year the leaves have gone flimp and there is only one flower which has turned into a pea sized green strawberry.
What should I do next?
Thank you.

 

It sounds to me like they dried out, they can be very dramatic when that happens. Can you add a couple of photos to help us out?

 

I'd agree that drying out is one of the most likely reasons @Sarah Eley . Strawbs need lots of food and water, and those bags will dry out pretty quickly if you aren't careful. The mix the plants are in can contribute to that too.
Strawbs also need rejuvenated every few years, so they may also be very congested depending on how long you've had them. They produce runners, which are then grown on for future harvests, so there could be too many in the bags. If there's only one flower, it sounds like nutrition is the biggest problem, along with that congestion. The size of the bags is also a factor.

Photos will definitely help, as well as some more info about the age of the plants and the care they've had etc.

 

Also worth lifting one up and checking what the roots look like as they could have been chewed away by Vine Weevil grubs which love Strawb plants, though they might not be there now as they may have hatched out into the Adult form.

 

I should have said they are alpine strawberries. The leaves are not upright, they've gone limp.

 

Here they are after a bucket of water and some tomorite.
