The problem with my version was that the pot sat directly under a Japanese Snowbell tree (Styrax japonica). The hoses would become plugged with petals or fruit, and it's not easy to remove anything at that point.
Looking at this image, I think I'd go this route and use one pipe, but I would cover the top with some screen.
I don't have any strawberry pots now, but this idea would be perfect for any tall, narrow flower or vegetable container.
Seems that I now have two methods to try out this year.
