Fertilizer Applications on Establishment and Growth of Three Groundcover Species in Sun and Shade

Abstract

Abstract Use of groundcovers in the landscape is often limited by slow establishment when compared to turf. Hedera helix L. (English ivy), Euonymus fortunei ‘Coloratus’ (Turcz.) Hand.-Mazz. (purpleleaf wintercreeper euonymus) and Liriope spicata Lour. (creeping lily-turf) were evaluated in full sun and 60% shade to determine the effects of fertilizer applications on establishment and growth. Limited fertilizer × species interaction was detected, which may have been due, in part, to the soil incorporation of mushroom compost. Establishment and survivability of Hedera in full sun may have been influenced by lack of acclimation from shade to sun. There was no significant difference in establishment rates between Liriope and Euonymus; however, under shade Euonymus did not develop its characteristic fall color. Hedera was established in one season under 60% shade and, of these three species, can be considered the most competitive with turf under similar conditions for low traffic areas of the landscape.
