Earthworks: Sunken Hugel Bed, Terraced Gardens and a Living Roof

Digging the Pit in 2022

Four years(2022) ago we dug a pit (approximately 10’ wide x 20’ long x 6’ deep) at the front of our property with the intention of installing a natural swimming pond. We ultimately decided the location was not very good. There was a lot of canopy cover which meant lots of leaves in the swimming pond which meant lots of maintenance. Plus, I had moved on to other projects and with the drought Central Texas has been in for the last few years I didn’t feel like it was the right time to try to establish a pond.

The pit in 2024

The impetus to fill in the pit came this past summer(2025). One of the large (~50 feet tall) hackberry trees at the front our property died. So, the solution became obvious. Fill in the pit with hackberry tree wood and cover it over with soil to create a sunken hugel bed.

The Hackberry on the tree on the left died. We went ahead and took down the one on the right to open up sunward exposure to this area

Hugelkultur is raised bed gardening technique where you pile up rotten wood, cover it with soil and plant on it. The rotten wood soaks up water like a sponge and slowly releases it providing drought resistance. The wood also provides nutrients as it breaks down and encourages other microbial soil life.

We decided to rent a skid steer as building the hugel would require moving ~20 cubic of yards of soil. So, while we had the machine on site we decided to take care of a couple of other projects like building a terraced garden and finishing the living roof on the cottage.
