Concrete roof tiles used with reo to make a curved raised garden bed. Soil from the surrounding path is used to build the bed. The recessed path is filled with thick mulch and acts as a infiltration basin to store water, which wick up into the garden bed.
We have been living in Bulgaria for over 5 years now. In the first year we knew nothing about gardening.The neighbours came and did everything. Now things are different, mixing GB with BG ways, we have success, well most of the time.
