This year I have been experimenting with growing strawberries in various sized pots.
I have about 40 plants in various pot sizes, ranging from a standard 6" pot up to large tomato pots, and I also have a group which I have grown in the ground as usual.
There did not seem to be a great deal of difference between them until fruiting time. Even though most of the plants were the same size, there was a significant difference in the size and quality of the fruit. The bigger the pot, the bigger the strawberry.
More importantly, the bigger the pot, the better tasting the strawberry. The ones grown in the ground were by far the biggest and were the strawberriest strawberries I have ever tasted. The large/middle size pots produced strawbs similar to the kind of stuff that we can all buy in the shops, and those in the 6" pots were small and positively tasteless.
Same variety, age, compost, location, feeding and watering regime.
I am not quite sure what to make of this, but assume that it has something to do with the importance of never letting strawberries dry out. It would appear that if their growth is checked in the slightest way, the effects on cropping are really significant. However, that is just my guess.
Any strawberry growing experts out the who can shed some light?
