Garden Planting Blend is a mix of 70% native compost 15% sandy topsoil 15% washed course sand. Our GPB is a rich medium for flower gardens and raised beds, and topdressing around non-native trees and shrubs. GPB also makes an excellent vegetable garden medium with the enhancement of peat moss, coco coir or a organic manure to boost nutrition. GPB retains moisture and provides the nutrients that are essential to growing plants. The loose compaction of the mix allows the roots of newly planted trees and shrubs to expand with minimal resistance, allowing for trees and shrubs to develop a strong initial root structure.
Native Compost, the primary ingredient in our GPB, is recycled organic plant material including grass, leaves, bark, pine mulch, and shrub trimmings. It is hot composted for several months before use. Gypsum is added to improve heavy soil structure and act as a general soil conditioner. It provides the correct balance of nutrition, organic matter, and particularly active bacteria that are vital to soil nutrition. Sandy Topsoil and Course Sand is added to the blend to assist with drainage, and provide a stable base for the root structures to grow into.
