Specialist compost for special varieties of plants, trees and shrubs.
The plants we look after are increasingly diverse and require diverse composts to meet their nutrition and soil structure needs. And because we are increasingly nurturing plants that are used to growing in different environments all over the world, specialised compost is required to help them grow to full health. For example, a cactus will need a free-draining mix that emulates desert conditions.
Here you will find a range of specialised compost, including compost for less typical plants such as cacti and succulents, and for bulb planting. We’ve also got a range of indoor compost types here, specially manufactured with higher nutrient levels to help indoor plants flourish.
So if you’ve got roses, a bonsai tree, carnivorous plant, shrubs or citrus plants — then we’ve got a specialist compost type for you.
Can’t find a specific compost type that you need? Contact us — we’ll be happy to help.
