Ornamental woody species grown in containers were investigated in two stages. Experiments with ornamental plants were established using one-year-old cuttings and seedlings of the following deciduous and evergreen woody species: Cotoneaster dammeri Skogholm, Berberis thunbergii, Potentilla fruticosa Snowflake, Ligustrum vulgare Atrovirens and Picea omorika. After planting into containers, fertilizers in the dose of 1 tablet (i.e. 10 g) per litre of substrate were applied either to roots level or on the soil surface in the container. Silvamix in the dose of 5 g.l -1 was used as the tested fertilizer in the second stage. It was applied during the planting in the form of tablets and/or a powder. Control plants were fertilized in the course of growing season using a common agricultural fertilizer Cererit Z. The annual plants increments were measured. These experiments demonstrated a long-term optimum effect of this product on woody species and an equal quality and efficiency of its tabletted and powdered forms. fertilizers, nursery production, growing technologies, ornamental plants Ročník LII 18 Číslo 2, 2004 Address Dr. Ing.
