You will need:
- Some (old) flowerpots, it's no problem if they're broken
- Rocks and stones
- Rock garden plants, possibly mosses
How to make it?
A broken flower pot can give a nice result because you can layer your garden. If you don't have a broken pot you can break one. This is easiest done with a hammer. Be careful not to cut your hands on the sharp edges. Wear gardening gloves or other protection.
Insert the broken shard horizontally in the broken flower pot. Maybe you need to break the shard again to make it a bit smaller so it will fit. Make sure you fill the space underneath the shard with soil, rocks and/or smaller shards. The soil should be pressed until it's pretty dense in order to prevent sagging.
Use some other, smaller, flower pots to create a nice 'tower'. Use soil, and press it, between all the flower pots to make sure the stack is built firmly. Put soil in the flower pots and plant the rock garden plants. Eventually decorate with rocks and stones.
- Rock garden plants normally don't need much water, so make sure excess water can leave the pots.
- Mix the soil from a bag with sand or very small rocks to improve the drainage.
- Make sure all flower pots have a hole in the bottom for drainage.
