PVC Pipe Garden

Cool concept hey! you can hang them by placing hooks on each end and have them hanging in areas like verandah's, or you can make stands for them, or simply secure them to walls and fences. You can also have them upright and put plants in them similiar to the Strawberry Barrel.
You can buy PVC piping and end caps readily at many places including plumbing and hardware stores.

Planter Pot Wall

It doesn't get much easier or simplier than placing pots vertically. The great thing behind this concept is that you can adapt it to suit your space and materials. The other advantage of planting in pots is that they are easy to work with and move around when required.
Visit your local scrap metal yard or recycling centre for materials you can use as a frame or grid, and also for hooks or wire to use to secure your pots.
