In depth articles

I believe that detailed knowledge and understanding provides an essential foundation for the work that I do in designing gardens for my clients; and that this is worth sharing with a wider audience. These articles are my own distillation of some of what I have learned over years of reading and study, and cover a range of topics in botany, soil science, design theory and many other areas of knowledge.

Where possible, I’ve attempted to explain my own understanding from first principles, meaning that some articles stray into core sciences such as chemistry and physics; and a few may be a little technical. I hope you find as much value in reading them as I did in writing them.

If you’re new to plant and soil science, you may want to read this article first.
