John started by showing us the conifers he was going to plant on the slate after it was modified.
He donned safety goggles and clipped carefully at the edges of the slate until he had formed a pleasant curved shape.
Next, he prepared the clay by rolling it and applied it to the slate, following the shape. Wire was added to position the conifers.
The trees were planted in compost and wired in, with a large tree near the centre and the other trees grouped around in varied distances to give a natural forest effect.
