We have lots of pallets sitting in the garage after foraging them from a 'free firewood' pile. Yesterday, MrShoestring turned some of them into a very big planter for the blueberry bushes.
The blueberry bushes need acid soil and are currently in some big pots. They have grown quite a lot and we were worried about them getting pot bound and not giving us quite so many blueberries this year !
He used a really big pallet as the base, so it stands away from the ground and won't rot so quickly. He will line it with leftover weed surprising fabric which we have been using on the fruit beds to save weeding during the summer. Even the nails he used were left over and he pulled them out of the panels and firewood that we've been burning. So a total cost of nothing except his time, it did take him all day.
However, I think it looks great, will definitely do the job and the only cost will be the acid compost to fill it ! So, I think it is a frugal win !
