This is a great way to have lots of strawberries, without the problems of slugs eating them. This method is great for balconies or gardens, were space is a problem. You plant the strawberries in the holes and on the mound at the top.
The containers can be smaller depending of your space; you will need for this container:
Two wheelbarrow loads of topsoil, one wheelbarrow load of good compost a Drill and jigsaw and about forty strawberry plants. You can get a friendly neighbour to help you with the cutting.
Its easy to cut holes if you have made a nice hole with a drill, the finished holes are about 8cm in size.
When all the holes are done, (you can leave out any at the back as no sun would be able to reach there) start filling the barrel. Add different materials as you are filling.
I usually wait a month before planting in the strawberries, I start when the mount at the top is sunken to the level of the barrel. If you wish to start right away, then when planting place the plants so that the roots are just above the holes (having the leafs sticking out through the hole). This brings the plants level with the holes when the soil settles.
I will add the finished barrel in summer, when there are actual strawberries on the plants.
Note that I used some old paint that was ready to be thrown out. It does look better than the bright blue ( especially in real life). I would normally never bother as to some degree the plants them self’s would cover most of the barrel. I used some of my own compost and two shop bought organic compost bags.
