I have some strawberry plants in my back garden which have been there for a few years and have until recently been left to their own devices. They were in some dry sandy soil under a tree and didn't seem to produce any fruit (although we didn't go into the garden much so maybe the birds ate it). About a month ago I dug them up and put them in my new veg patch with lovely fresh compost and started watering them every day. They have started to produce fruit but the berries are tiny and don't taste nice at all - they are dry and very sharp. The fruit are dark red on the outside but white on the inside.
They are in the sunniest part of the garden but that's still quite shady, they get morning and evening sun only (north facing garden).
Does anyone know why this is and what should I do? Should I just give up on these plants, dig them up and get new ones? Or is it the lack of sun?
