Hi All,
I've been given some strawberry plants which, I've been warned, will spread like wildfire once planted. As my family love strawberries, I was thinking about making a 4x1x1' garden bed for them which hangs off my balcony railings. They would get full sun and rain, and would be handy to eat any time from the deck. What I'd like to know is what wood to use, and what method of bracing the bed to the railings? I've thought about a 2x1" on the inside of the railing with a couple of arms attached to the side of the bed, though I have doubts. What about hooks over the top railing and a rubber foot in between the bottom railing and the bed? May I ask your thoughts on wood, bracing, how to coat/waterproof the wood?
Brown = railing
Green = garden bed
Blue = bracing

Thanks,
Jason
