With the rising cost of sphagnum peat, nurserymen are looking at alternatives for growing substrates. Daddy Pete's plant pleaser is a product of composted cow manure. This study was conducted to see if composted cow manure could be used to grow containerized plants and replace sphagnum peat. Research was conducted using two Rhododendron cultivars, `English Roseum' and `Scintillation'. Plants of each cultivar were potted into 3-gallon containers. Test substrates were tested against the grower's standard mix, 80 pine bark: 20 sphagnum peat (% by volume), amended with 20 lbs Scotts Prokoke, 8 lbs dolomitic limestone, and 1.5 lbs step minor element package/1.7 yard3. Test substrates were treated equally. Daddy Pete's plant pleaser can work as a substitute for peatmoss in a growing mix. The Daddy Pete compost grew just as good a plant as the Buds & Bloom standard. Watering management turns out to be a factor because the compost generally held more water, therefore not needing irrigation as frequently.

Abstract Fraser photinia, ‘Plumosa Compacta Youngstown’ juniper and ‘Hino-Crimson’ azalea were grown in pine bark amended with a factorial combination of five rates (0, 0.9, 1.8, 3.6 and 7.2 kg/m3) (0, 1.5, 3, 6 and 12 lbs/yd3) of olivine, a magnesium ortho silicate containing 27% Mg and four particle sizes of olivine. Calcium carbonate (38% Ca) at 2.4 kg/m3 (4 lbs/yd3) was incorporated into all olivine treatments. A separate treatment utilizing 4.2 kg/m3 (7 lbs/yd3) dolomitic limestone (22% Ca, 11% Mg) was also included to serve as a comparison to dolomitic limestone. In general, Mg concentration in the media increased with increasing olivine rate and decreasing particle size. Media P, K and Ca concentration and pH were not affected by olivine rate or particle size, nor were they significantly different from the treatment containing dolomitic limestone. Foliar Mg increased with increasing olivine rate in all species. Foliar K decreased with increasing olivine rate for ‘Hino-Crimson’ azalea and Fraser photinia. Top dry weight of ‘Plumosa Compacta Youngstown’ juniper was not affected by olivine rate or particle size while top dry weight of ‘Hino-Crimson’ azalea and Fraser photinia increased quadratically with increasing olivine rate, with the maximum occurring at 0.9 kg/m3 (1.5 lbs/yd3) and 1.8 kg/m3 (3.0 lbs/yd3), respectively. These maximum top dry weights were significantly heavier than plants grown with dolomitic limestone.

Rooted cuttings of Euphorbia pulcherrima Willd. ex Klotzsch cv. Gutbier V-14 Glory were planted in 2-liter containers with growth media having 0% to 75% composted cotton burrs (CCB) in combination with sphagnum peat and/or composted pine bark. Leachates from media with 50% or more CCB had higher initial electrical conductance (EC) (3.7 to 4.0 dS·m-l) than that from media with 25% or no CCB (2.8 to 3.0 dS·m-l) 2 weeks after planting. The differences in leachate EC declined after an additional 9 weeks. Media containing CCB produced slightly shorter and narrower plants with 10% smaller inflorescences and less dry weight than plants grown in a medium consisting of equal volumes of peatmoss and bark. Number of branches and bracts, days to bloom, and plant grade after 30 days under 15 μmol·s-l· m-2 photosynthetic photon flux were unaffected by media.

Abstract Four experiments were conducted with selected woody landscape plants in containers to compare container media consisting of composted rice hulls and a lightweight clay aggregate (Arkalite) to pine bark and sand. Plant growth in the inorganic components of sand and Arkalite was generally similar. Plant growth in organic components of 100% composted rice hulls or 50% composted rice hulls and 50% pine bark compared favorably with the growth obtained with 100% pine bark as the organic component. Excellent growth was obtained with composted rice hulls only when not amended or amended with small amounts of dolomitic limestone. Use of composted rice hulls should be based on costs and availability.
