Rooting Response

Scarcity of landfills has resulted in increasing need for alternative disposal or reuse of industrial organic wastes such as paper mill sludge (biosolids). The objective of this study was to evaluate and compare the rooting response of stem cuttings from six species of deciduous landscape shrubs [coralberry (Symphoricarpos × chenaultii Rehd. 'Hancock'); flowering almond (Prunus triloba Lindl. 'Multiplex'); honeysuckle (Lonicera × xylosteoides Tausch. 'Clavey's Dwarf'); mock orange (Philadelphus × virginalis Rehd. 'Minnesota Snowflake'); purple-leaf sandcherry (Prunus × cistena N. E. Hansen); and viburnum (Viburnum dentatum L.)] under mist and 50% shade (outdoor lath) in flats filled with 100% perlite medium, or perlite mixed with 15, 30, 45 or 60% of fresh paper mill biosolids, by volume, of one of four sources (Atlantic, Domtar, Thorold, and QUNO). There was little or no adverse effect of the biosolids, despite wide variability in rooting response due to species, source and/or level of biosolids. Regression analyses indicated that, with few exceptions, the percent rooting, mean root number per rooted cutting, and length of longest root per cutting increased linearly or curvilinearly, or was unaffected, when regressed over level of biosolids. Optimum amounts of biosolids in the rooting medium ranged from 30 to 60% by volume. The electrical conductivities of the biosolids-amended media were acceptable (0.1–0.3 dS m−1) for rooting of woody cuttings and pore space characteristics were comparable to, or exceeded those of, perlite.

Linear Reduction

Stem cuttings of seven deciduous landscape shrubs {silky dogwood (Cornus amomum Mill.), coralberry (Symphoricarpos orbiculatus Moench), Peegee hydrangea (Hydrangea paniculata Siebold. `Grandiflora'), Bridal-wreath spirea [Spiraea ×vanhoutteii (C. Briot) Zab.], spirea (Spiraea ×bumalda Burv. `Goldmound'), fragrant viburnum (Viburnum farreri Stearn), and weigela [Weigela florida (Bunge) A. DC. `Variegata Nana']} were rooted under mist in 100% perlite (no sludge) medium or in mixtures of 10%, 20%, 30%, 40%, 50%, or 60% (v/v) of raw paper mill sludge and perlite. There was a large linear reduction in percent rooting of viburnum (from 80% to 21% with 0% and 60% sludge, respectively) in response to increasing level of sludge. The mean root count per cutting also was significantly decreased, from 14 to 5. However, the length of longest root was unaffected. In contrast, all the other species ranked good to excellent in rooting, regardless of the level of sludge. Differences, if any, in rooting performance were not of practical significance.

Conducting Research

The nursery/landscape industry has been one of the fastest growing agricultural sectors in Canada. Since 1980s, the Ornamental Nursery Research Program at the Horticultural Research Institute of Ontario (HRIO) has been conducting research which focuses on environmentally friendly production practices. Emphasis is on the use of composted or uncomposted organic wastes as amendments in container potting mixes. Various projects have evaluated mixes derived from wastes such as spent mushroom compost, paper mill sludge, apple pomace, and various types of barks. In the late 1980s and early 1990s, the scope of the research expanded to include composting and a wider assortment of wastes such as waxed corrugated cardboard, municipal solid waste compost, wood chips from pallets and furniture and demolition wastes, food wastes, and organic fertilizers manufactured from meat by-products, and selected industrial wastes. Presently, paper mill sludge is being evaluated as field soil amendment for growing nursery shade trees and also for use in rehabilitating marginal, non-agricultural land.

Abstract Perlite and mixtures of milled sphagnum peat and perlite (1:16, 1:8, and 1:4 by vol) were compared as rooting media in a propagation system utilizing subirrigation with minimal mist for rooting softwood stem cuttings of nine woody plant species. The influence of rooting medium on percentage rooting, number of roots per rooted cutting, and length of the longest roots on each cutting varied with species. Composition of the media had no effect on percentage of cuttings that rooted, number of roots per rooted cutting, or length of the longest root of ‘Late Blue’ highbush blueberry (Vaccinium corymbosum L. ‘Late Blue’). Cuttings of Amur maple (Acer ginnala Maxim.) and ‘Ruby Spice’ sweet pepper bush (Clethra alnifolia L. ‘Ruby Spice’) produced the longest root in 1:4 peat:perlite, and cuttings of ‘Ruby Spice’ sweet pepper bush produced the greatest number of roots in 1:8 peat: perlite. Cuttings of redvein enkianthus [Enkianthus campanulatus (Miq.) Nichols] produced more roots in 1:8 peat:perlite than in perlite, and longer roots in 1:16 and 1:8 peat: perlite than in perlite. The number of roots per cutting of ginkgo (Ginkgo biloba L.) was greatest in 1:16 peat: perlite. Cuttings of Carolina silverbell (Halesia carolina L.) rooted in the greatest percentage in perlite, and cuttings of panicle hydrangea (Hydrangea paniculata Sieb.) rooted in the greatest percentages in perlite and 1:8 peat: perlite. The number of roots per cutting of ‘Kwanzan’ cherry and ‘Shasta’ doublefile viburnum [Viburnum plicatum Thunb.var. tomentosum (Thunb.) Rehd. ‘Shasta’] was greatest in 1:16 and 1:8 peat: perlite. Root length per cutting of ‘Kwanzan’ cherry (Prunus serrulata Lindl. ‘Kwanzan’) increased with an increase in the amount of peat in the medium. Rooting medium pH decreased and moisture content increased as the amount of peat in the media increased from 1:16 to 1:8 to 1:4 (peat:perlite, by vol).
