A think it needs to be pollinated but you could do it yourself with a small brush.

Lots and lots of sun. The more pollination they get, the more, bigger and earlier strawberries they grow. I found an article in Swedish about it:

» Fler insekter gör bättre jordgubbar (More insects makes better strawberries)

#1 Okay I looked out how to pollinate it with a brush. Hoping I did it correctly and it  works 

#2 Too bad I have bad insects killing my outdoor plants every year 

#4: Do you know what kind? Have you searched for a solution? Are they a flying or walking kind?

#5 Yes I have. A report from Stockholm University found that this type of bug is a problem now in the area due to the warmer summers. It looks like a small moth. I have to keep the apartment Doors and windows closed because they eat my indoor plants too. I’ve tried many bug sprays and predatory bugs but the best I have found is to keep them away from the plants at all costs.

How about putting up a birdhouse next to the balcony or on nearby trees? Black and white flycatchers eat flying insects, thousands of them. I've been planning to build a birdhouse for them to get rid of mosquitoes and wasps around the house.

#7 I could try that!

I have so many strawberries growing now I don't know what to do with them lol.

You mean the berries have started showing?

Yes I have eaten two!

That's very early. Sell them to restaurants and make a fortune. 😀
