Large Wooden Planter
I have just built a large two tier planter out of sleepers. See pic attached. I'm struggling to find any advice on the internet that answer the three questions I have, so hopefully you can help!
1. Should I line the planter sides to protect the wood? The base of each tier is actually soil because the indian stone stops at the first tier. If I should line the sides, will plastic bin liners stapled to the wood suffice?
2. What do I fill the tiers with? purely soil, purely compost or a mixture of both? Or something else? Im not planning on growing any fruit or veg in the planters. It will be used simply for plants, flowers and a few climbers at the back to hide the wall. The front tier is not to deep, i'd say 50cm or so, however, the back tier is double the depth so will require a lot more.
3. Any suggestions for a good climber, something that wont eat away at my neighbours mortar. The wall and planter only gets the sun in the morning. Its quite a shaded spot.
Thanks in advance!!
