Abstract
Rooted cuttings of poinsettia (Euphorbia pulcherrima) were grown in Sunshine Mix and 12 blended media containing various proportions of: a) composted yard waste; b) co-compost (sewage sludge composted with municipal solid waste); c) peatmoss; d) perlite; e) pine bark. Amount of composted waste products per blend varied from 50% to 78% by volume. Three fertilizer regimes: 1) O; 2) Osmocote 18/6/12; 3) Osmocote 39/0/0. Osmocote was applied after potting to render equal amounts N. Sunshine Mix with 18/6/12 Osmocote produced greatest dry weight. The more successful compost blends produced 82-85% of this dry weight without Osmocote. Several compost blends achieved greater dry mass without fertilization. Plants grown in compost media blends showed little preference for Osmocote treatments. All plants grown in compost blended media exhibited marginal chlorosis and neurosis of leaves to varying degrees. Plants grown in compost blended media tended to produce greater average bract size than plant height. Leachate tests revealed poor infiltration of water in media with high proportions of co-compost.
