Hi All,
I am thinking about a raised redwood box to plant a small garden in on the side of my house.
So far I have decided to make it redwood because 1) it takes a very long time to rot, and 2) no chemicals to screw up my organic gardening. Does this sound right?
And, I would like it twenty feet long and three feet wide. Three feet so I can reach over and weed the thing with out a lot of stretching and stooping. Does this also sound right?
Questions:
1) what goes on the bottom? Nothing so water can drain out? Do I put a floor on the underside of the box? The dirt (ha ha) it will be sitting on is "decomposed sandstone" (like decomposed granite, only way, way uglier.) There is no nutritional value in it -- everything has to be replaced, amending does not work.2) how tall should the box be? Obviously, the taller, the less stooping but the greater expense in filling it. Root need some root to grow.
3) screws or nails? As redwood dries out, nails tend to fall out4) what do I fill it with? Straight compost? or a mixture of both? What ratio? (The compose place sells both.)
Anything I missed?
Many thanks,
