This was an interesting job, converting half the chook run to a high garden. Three of the walls walls were already there so I added the fourth to separate the chooks from what they love most. Then it was wood chip on the bottom to lift the level.
Plastic to hold the sand.
You will notice the liner does not go all the way to the top of the garden. This is because the garden is wider than normal(1600 mm). In a conventional garden this would be too wide to reach the centre comfortably but as the garden is nearly waist high it is not a problem.
We planted a row of snow peas, Chinese cabbage, spring onion, beetroot, Chinese spinach, choy sum, pak choi, coriander, and carrot.
One week later the little seedlings are starting to come up. Having a whole garden growing from seed is efficient regards to water. Once they are all up and running in another week or two they will take their water from the reservoir so no more hose watering for this garden.
Apart from the vegetables mentioned above, May is a good time to plant cabbage, onions, spinach and silverbeet.
