Question about Keter Easy Growing

Hello Nicole . These parts are really great ! You only need to know the structure of a raised bed. Then you can fill in about 20 cm of soil. I started at the bottom with a little east on top of some straw and very important horse manure from the farmer . and then soil from the nursery . We have harvested strawberries, raspberries, lettuce for the second time, kohlrabi and herbs. Have fun ! Jörg
