Soil Association and Vegan Society approved Made in Britain Eco-friendly and safe for wildlife. Natural Grower is an approved organic plant-based mulch. A sustainable by-product of a British renewable energy plant, it is made during the process of generating green electricity for the National Grid. The mulch can be dug into soil before planting or spread over the surface to be taken down by worms, and will help retain moisture while improving soil health and structure. Perfect for mixing into grow bags, hanging baskets, pots and vegetable and flower beds, as well as planting trees and roses. Used as directed, the mulch slowly releases a rich mix of nutrients, including nitrogen, phosphorous, potassium and other trace elements to promote sustained healthy growth (NPK ratio: 4.1:2.2:3). Chemical free and pH neutral. Always read instructions before use.
