We are fortunate in having a small factory nearby which disposes of mainly small, hardly used pallets. Being only 1/2 mile away I make best use of this facility for firewood and 101 other uses. In the garden I have discovered that upturned, small pallets, with wooden strips nailed to the sides make excellent, instant raised beds. Just create a shallow, flat trench and lay the pallets end-to-end.
This photo shows our rear garden, in early spring with beds fleeced against further frosts and blue trays of seedlings being hardened off. As in all garden structures, these pallets will of course offer refuge for slugs and the like but my argument would be that these will be around somewhere anyway- best to have them where you know where to look and dsipose of them regularly.
