We do have one colourbond bed but it's just not viable financially to deck out our entire yard with these, as lovely as they may look. Funnily enough before they came popular I was hunting round for old water tanks to grow veges in lol and now 'colourbond' planters are all the rage!
So we'll get old bath tubs, raise them up on a couple of courses of bricks with mesh between the bricks and base of the bath (to stop rust if they're that kind?), then 'wrap' them in discarded/reclaimed corrugate to pretty them up, eventually at least, and as we gather the colourbond. It was initially an idea to make our own colourbond planters but it would mean corners (because we don't have a corrugate bender) and then enough to support them. So this way with the baths as the planters, the corrugate is the 'finish' and not the 'structure', so it won't need reinforcing because it won't be containing a load.
Benefits of bath tub planters:
- raised off the ground - better height for working and picking
- not planting into existing soil - no grass or very minimal grass can get in. More idea over exactly what soil is going in there.
- less soil needed. Our big colourbond planter we filled the bottom with 'sand' and then put the manures and good stuff on top of that. So 'waste' at the bottom - and certainly if you filled the whole lot with compost/manure etc esp if you had to buy it, it would be more resources in the set up. With the bath tubs, pretty much it's only the soil you'll use, that will go in.
- Can get them secondhand/reclaim for free or for small cost. The more battered the cheaper they'll be. bonus :)
- Anyway, my q was, what baths aren't ok?
- how long would enamel ones last (if they're ok to use) before they rust through?
