The market for large plants is increasing steadily; however, weed control in large containers present new production problems for growers. Experiments were conducted to evaluate pine bark mini-nuggets for weed control in 11 and 27 liter (#3 and #7) containers. In October 2004, Gardenia jasminoides (August Beauty gardenia) were seeded with oxalis, and Lagerstroemia indica 'Natchez' (crapemyrtle) with bittercress in 27 liter (#7) containers. In March 2005, Hydrangea quercifolia (oakleaf hydrangea) were seeded with oxalis and Ternstroemia gymnanthera (ternstroemia) with bittercress in 11 liter (#3) containers. Treatments consisted of mulch applied at depths of 0, 3.8, and 7.6 cm (0, 1.5 and 3.0 in), with seed applied either above or below the mulch. A separate group of treatments were included similar to the above except that a granular preemergence herbicide was applied after mulch application. Growth of crapemyrtle and ternstroemia were similar regardless of mulch depth. With gardenia and oakleaf hydrangea growth differences existed but there were no consistent trends among treatments. Season long weed control was obtained in all treatments that included 7.6 cm (3.0 in) mulch depth. [ABSTRACT FROM AUTHOR] |
