Q.can i move my strawberries in a different container?
Hello, I live in northern Italy. I have two concrete containers with strawberries in the garden, and the yield is sort of poor, with a lot of fruit falling to leather rot.
Do you think moving them to a plastic container with drain holes and adding some good soil (and a tarp, which they don’t have now) could improve things, or should i just wait for the autumn to do it?
Bonus question: one container is doing MUCH better than the other, in terms of foliage and fruits, even though they are 5 feet apart in the garden, why could that be?

I do think that the concrete containers are to blame. They will probably not allow for proper drainage, which is the primary cause for leather rot.
It will be best to move them as you have proposed, and then treat them with A TABLESPOON of WETTABLE SULFUR and a HANDFUL of DOLOMITIC LIME per container also. This will help treat and prevent future fungal infections, as well as condition the soil.
Alternatively, you can try spot sprays, and fungicides. This article will help: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
