Good compost is at the heart of our orchid culture. After 30 years of experimenting we use just high quality course bark for all our plants. It allows us to keep plants well watered while maintaining perfect drainage, lasts for ages, is sustainable, and is safe to handle. We find that we do need to process the bark we buy by sieving to remove and dust, small particles and wood, that would reduce drainage and break down too quickly.
We have our processed bark available again at the shop thanks to Ed and his compost team.
