Estimation of the growth of selected taxons of ornamental shrubs depending on the fertilization with Osmocote Exact Standard (5-6 M)
Summary.

Defining the usefulness of fertilizer with a controlled release of alimentary components, namely Osmocote Exact Standard (5-6 M), was the main aim of the carried out investigations on the container-growing of the following species: Juniperus × pfitzeriana ‘Mordigan Gold’, J. virginiana ‘Tripartita’, Thuja occidentalis ‘Globosa’, T. ‘Smaragd’, Berberis thunbergii ‘Erecta’, B. ottawensis ‘Superba’. It also aimed at deliminating optimum fertilizer doses sufficient for one vegetative season, arriving at optimal yield. The plants were grown in high-peat substrate fertilized with increasing doses of Osmocote Exact Standard (5-6 M). The carried out investigations showed the fertilizer was adequate for container-growing of the studied species of ornamental plants. The most optimal dose of the fertilizer Osmocote Exact Standard (5-6 M) for container-growing of T. occidentalis ‘Globosa’, T. ‘Smaragd’ and B. thunbergii ‘Erecta’, as well as B. ottawensis ‘Superba’ was 6 g∙dm-3, while for the same type of cultivation for J. × pfitzeriana ‘Mordigan Gold’ and J. virginiana ‘Tripartita’ the appropriate dose of the fertilizer should oscillate between 2 to 4 g∙dm-3 of the substrate.
