Even though this hugelkultur herb spiral gets only 3 hours of sunlight in this urban food forest, it has done fairly well - maybe the soil health practices help. The herb spiral was filled with carbon-heavy wood core material from my yard last year - layered with spent mushroom logs on the bottom, branches, twigs, leaves, soil, and wood chips on top.
The wood core materials act like a sponge, helping to keep my yard from flooding after all this excess rain, and storing it where it can slowly be released upward for plants during dry spells, like we had last summer with the drought. The mediterranean herbs that like it dryer, are on top, with herbs closer to the bottom that like it moist, when the rainwater flows down the spiral slope.
Except for the initial planting of the annual herbs in the spring where i watered it twice, nature and the hugelkultur self-sustaining system have taken care of the rest of my watering this year!
And I was surprised, as I think the brick, as well as providing seating areas for folks on tours, and a central place to put my tools so I don't lose them in the yard, lol, may absorb sunlight in the winter, radiating warmth and buffering the rosemary and lavender from the cold as they survived the winter.
I planted the strawberries as a ground cover to help retain moisture around the herb plants, but they really liked the hugelkultur spiral, blooming throughout the spring and summer, and almost took over the herbs!
Bonus - with the wood materials layered in, I won't have to add any additional nutrients or fertilizers - the wood materials breakdown over time, with the mycelium (maybe I'll get mushroom next year), feeding the microbes that will make the nutrients available for the plants, as I think the plants look pretty healthy in general.
I have (bottom to top): blueberries in the container, lemongrass, red form of common violet, peppermint, tulsi, pineapple sage, Thai basil, nasturtium, red basil, thyme, sage, lavender, rosemary, and strawberries!
Anyone else have experience with hugelkultur in herb spirals or garden beds?
