The garden benefits from coastal and mountain views with approx three acres of deciduous woodland, originally planted in the C19, mostly with beech. We have protected the remaining old trees, encouraged natural regeneration, and enriched the woodland with some plantings. The garden we created inc lawns, herbaceous borders, and a small wildlife pond. Bio-char demo on trial on wildflower plots.
