climate-controlled greenhouse at the G.C.Horn turf field laboratory at the University of Florida in Gainesville. Floratam St.Augustinegrass is being compared with a mix of ornamentals including canna, nandina, ligustrum and allamanda. Plant material is growing in 80-gallon plastic pots in an Arredondo fine sand. There are three fertilizer treatments (16-4-8 quick-release, 15-0-15 quick-release,...

ISHS II International Symposium on Tropical and Subtropical Ornamentals Propagation of an Indonesian native species Tetrastigma glabratum (Blume) Planch, a medicinal plant from Mount Prau, Central Java, Indonesia

Many herbaceous perennials would benefit from additional branching to provide fuller pots in shorter production times. Cyclanilide (Tiberon, OHP, Inc., Mainland, PA, USA), a new product recently labeled in the USA for branching of woody ornamentals, was evaluated on several herbaceous perennials over two seasons. Cyclanilide was applied as a foliar spray to established plants grown in 1.1-L pot...

The genus Allium L., Amaryllidaceae includes numerous economically important vegetables used primarily for their unique flavors. Most people recognize the main vegetable alliums, such as bulb onion and shallot (A. cepa), garlic (A. sativum), leek (A. ampeloprasum var. porrum), and chive (A. schoenoprasum). However, there are numerous cultivated vegetable alliums of more regional importance, inc...

While consumers are interested in organic or biorational alternatives to synthetic fungicides for the control of diseases of ornamentals as well as vegetables and tree fruits in residential landscapes, relatively few field trials have been conducted to establish their performance against ornamentals diseases. Weekly applications of Armicarb® 100 (potassium bicarbonate) controlled powdery mildew...

1 Multiple factors are known to influence tree seedling establishment, yet the degree to which these factors depend on each other and on spatial context is largely unknown. We examined the influence of herbaceous competition and water and nitrogen limitations on tree seedling establishment as functions of distance from trees (within-site spatial context) and site history (between-site spatial c...

DRESENT INTEREST in grow' ing ornamental plants has created a demand for information on the control of the insects, mites and other pests attacking them. Requests for this information come from home gardeners, florists, nurseries and contract applicators. Until recently very little attention was given the problem since there was no satisfactory way of estimating monetary losses of ornamentals d...

1. Globally, both climatic patterns and nitrogen deposition rates show directional changes over time. It is uncertain how woody seedlings, which coexist with herbaceous plants in savannas, respond to concurrent changes in water and nutrient availability. 2. We investigated competition effects between herbaceous vegetation and tree seedlings ( Colophospermum mopane ) under changed water and nutr...
