Next year I'm going to increase my growing area in the veg garden again. The bottom area is very wet and holds quite a bit of water. The plan is to install lots of cheap (free) raised beds using pallet collars stacked two high.
These worked brilliantly this year for growing my Jerusalem artichokes in, so the back fence will be lined with them giving me around ten 4ft x 3ft raised beds to house some of my more "unusual" crops and as a way of increasing a few of our staples like leeks.
When I picked this spot for the garden I didn't realise how wet it got down the bottom, it was the obvious place though and once I get round to putting a drain below it it should be much better, but until then it's raised beds for the last 30ft of veg garden (the rest is fine as it all slopes that way).
These pallet collars are no good for one of my winter projects though, as I have a crop planned that will out live them by several times over - Asparagus. I've been looking at all the types of raised beds I could build and I have my usual problem of wanting to have my cake and eat it to.
I want it to cost very little and I want it to last for ages! Is that too much to ask? It's going to be 20ft long by 4ft wide and about 18 inches high, so hopefully enough to give us a good spring feeding in a few years time.

| My old garden raised beds made with half round rails |
Half round rails - I did this at our last garden but I know they won;t last that long, in this wet spot I'd give them 5 years tops!

| Some rather brilliantly made compost bins at my friends fathers garden using railway sleepers and galvanised steels concreted in to hold them in place |
Sleepers and metal posts - sleepers are expensive, old ones have lots of creosote that will leak into the ground and new ones won't last!
 |
| Friends fathers garden - Slabs used on edge to hold back soil |
Concrete slabs - difficult to install and will be difficult to get hight, would probably need a small footing as well, making it very permanent.
 |
| Friends fathers garden - Blocks laid to form a large raised area to the garden |
Blocks - A good solution except for the need for footings and if they were to lie in the wet all winter heavy frosts might destroy them (although I can get frost proof blocks).
At the moment I'm thinking of building the raised beds out of corrugated galvanised sheeting with a wooden top and frame to hold it in place. The frame will be easy to replace when it rots and the sheeting should last as long as the asparagus crops for.
What would you use for a long lasting raised bed?
