RAISED BOG PEAT AS THE BASIC MATERIAL FOR THE PRODUCTION OF RHODODENDRON AND AZALEAS - FORMATION, EXCAVATION, PROCESSING, SUBSTITUTES
Due to its favorable properties raised bog peat has a dominating position in growing media for the production of rhododendrons, azaleas and other acidophilic species. Most other horticultural crops are also cultivated in peat-based growing media. The process of bog formation, peat excavation and processing are outlined. The physical and chemical properties of various possible components are compared with the requirements on growing media for Rhododendron and evaluated accordingly. Raised bog peat can be substitued for by other organic, mineral or synthetic materials only to a certain extent, because of their usually less favorable properties. Discussions on bog conservation, the use of waste materials and new growing techniques enhance the search for alternative substrate components.
