His Royal Highness has taken many steps personally to live in a more sustainable way.
Here are just some of the many ways the gardens are managed with the strictest sustainable principles:
- The Highgrove Gardens cover 15 acres in total – all of them organic.
- Wood pellet fired boilers (biomass) to heat Highgrove House, The Orchard Room, stables and offices.
- Most of the electricity is sourced from a renewable energy supplier and from solar panels, which is on the farm barns. The electricity is used in Highgrove House and the Orchard Room.
- Ground source heat pumps to heat the staff cottages and the green houses, and an air source heat pump to heat the Gardeners’ Mess and some of the workshops.
- A specially built reed bed sewage system, much loved by dragonflies at its treatment end, is used for all Highgrove’s waste.
- Gutter rainwater is collected into tanks and used in the toilets in the Orchard Room. The rainwater is also used to irrigate the garden.
- The gardeners make their own compost and leaf mould.
- A willow “ramp” is placed in each water feature to provide an easy exit in case any wildlife inadvertently fall in.
- 200 chickens roam areas of the Estate under a mixed range of fruit trees. From these hens around 4,200 eggs are collected every year. The eggs are used in the Orchard Room restaurant and sold in the Highgrove Shop.
- There are two fountains in the garden providing running, open water for birds throughout the year.
- The Highgrove Estate is also the location of Home Farm, a centre of excellence for organic farming.
