I was thinking of using a large compost bag, and cutting holes out of it, like a strawberry pot.
That's the way I do it.
10 plants to a 56 ltr bag of compost. The bags are on a table. I cut 10 holes in the top for plants plus another two for watering. I insert an old pop bottle into the watering hole and pour into that - much easier and quicker.
Also cut a number of short slits along the bottom of the bag for drainage, otherwise the rots will rot.
First year I don't add any feed, but second and third I do. After three years, replace plants and bags.
Pro's - Don't get slugs or weeds. No bits of soil in the fruit. No bending over to pick. Runners are easy to harvest/control.
Con's - Need watering regularly, more so than if in the ground. Cost - I pay £4 or £5 for each bag. Bags need putting on the ground over the frost period - their heavy and moving could damage the root systems, so need to be careful (& not buy too big a bag that I cant lift).
I am tyring a number of different bags. Have tried Mirical-Grow Multi-P. (yellow bag), Mirical-Grow Moisture control (blue bag) and Levingtons Multi-P with waterlock (red bag). All appear to work equally as well.
I'm going to try a bag of farm manure this year and maybe a double thick growbag.
