Pine Tree Substrate, Nitrogen Rate, Particle Size, and Peat Amendment Affects Poinsettia Growth and Substrate Physical Properties


Poinsettias may be grown in PTS with peat moss amendment


It is recognized that alternatives to peat must be developed to meet environmental concerns pertaining to mining of peat bogs. Also, peat supplies can also be limited by wet weather conditions that restrict harvest during certain times of the year. These concerns, coupled with increasing fuel (transportation) costs, have led to increased costs of peat substrates. Therefore, there is an increased interest in less expensive and readily available substitutes.
