“…Hartley (1992) reported that mixtures of peat and perlite, vermiculite or processed wood bark and containing at least 50% sphagnum peat can be used to grow poinsettias. Peatmoss is the most desirable form of organic matter to include in a poinsettia growth substrate (Barnes et al, 1994;Tomati et al, 1993), but it is becoming increasingly expensive or unavailable (Garrison, 1995;Sanderson and Martin, 1974). As a result, greenhouses are looking for alternatives to the substrates currently used: mixtures of peat, pine bark, vermiculite, and perlite.…”

“…Peatmoss is found in wetland ecosystems and the public and scientific community are concerned about the negative environmental impact of harvesting peat (Barber, 1993;Barkham, 1993;Buckland, 1993;Edwards and Fletcher, 1988). One way to reduce or stop peatmoss harvesting for container plant production is to find an acceptable alternative with similar characteristics (Garrison, 1995;Sanderson and Martin, 1974). An alternative substrate may present additional advantages over peatmoss since peatmoss supplies can be limited when weather conditions restrict harvest.…”

Experiments were conducted to evaluate earthworm castings (vermicompost) as a substrate for poinsettia (Euphorbia pulcherrima Willd.) `Freedom Red' production. Vermicomposts produced from sheep, cattle, or horse manures were mixed at different ratios with 70 peatmoss: 30 perlite (v/v) to create 13 substrates. Chemical and physical properties were measured on all substrates used. Growth index, foliar and bract area, and dry weight were greater on plants grown in substrates with castings from sheep or cattle manure. These castings had greater initial nutrient content than the castings from horse manure. Mixtures of castings and peat produced better plant responses than castings alone. Better plant responses were sometimes associated with values outside the recommended pH and electrical conductivity levels for poinsettia production. The highest values obtained for growth index, foliar and bract area, dry weight, and root development were produced in the substrates with moderate pore space or water holding capacity. Substrates with greater air space produced plants with greater dry weight and root development than substrates with less air space. The highest quality plants were grown in substrates with 25% castings from sheep or cattle manures.

“…Various studies have demonstrated the necessity for evaluating fertilizer sources (2,4,6,10), levels, and methods o f application (1,2,5,11), in container production. H ow ever, results may be variable due to different plant species response, fertilizer sources, methods o f application and rates, particularly in different types o f media (7,8,9). Furuta (2) suggested the use o f controlled-release fertilizers for production o f container-grown ornamentals was the best alternative to other nutritional programs.…”

Effects of Application Methods of Controlled-release Fertilizers on Growth and Quality of Rhododendron obtusum ‘Hinodegiri’ Grown in Various Media1

Rhododendron obtusum (Lindl.) Planch. ‘Hinodegiri’ responded to the different fertilizer sources and application methods similarly regardless of growing media. Plants top-dressed with Osmocote 18N-3P-10K had a significantly higher growth index, larger stem caliper and increased fresh weight than plants top-dressed with Pro-Grow 24N-3P-10K. Incorporation of either fertilizer source resulted in reduced plant growth and quality. The best fertilization method was a surface application regardless of fertilizer source or media.

“…Composted municipal refuse, which sometimes is treated with sludge, has been used to grow ornamentals (3,5). Only 2 reports (2, 6) appear to have been published on the use of sludge, without municipal refuse, in greenhouse media to grow ornamental plants.…”

Chrysanthemum plants (Chrysanthemum morifolium Ramat. cv. Bright Golden Anne) were grown for 84 days in plastic pots containing 6 different media treated with inorganic fertilizers or liquid digested sewage sludge at 50, 100, and 200 ml/week. Plants grown in 1 soil: 1 sand: 1 peat, 1 soil: 1 sand, and 1 soil: 1 peat were similar to each other in size, and larger than plants grown in 1 sand:1 peat, all sand, or all peat. Peat-grown plants were smallest. Plant size and flower diameter decreased with increasing rates of sludge application. Plants fertilized with inorganic sources of fertilizer looked the same as those grown with 50 ml/week sludge (6 mm), except the sludge-treated plants were shorter and had a smaller dry weight. Plants treated with 50 ml/week sludge had flowers with a diameter and dry weight equal to those of flowers grown with liquid or pelletized inorganic fertilizer.
