Comparison of weed control techniques to establish three ground cover species

C.L. Foo, K.C. Harrington and M.B. MacKay

ABSTRACT

Weed control strategies for establishing three ground cover species were investigated by planting them in late spring, then assessing eight different control treatments during the following 14 months. The prostrate woody Coprosma acerosa 'Taiko' established best with black weed mat mulch and EcoCover paper mulch, although bark mulches also gave reasonable establishment rates. The brittle succulent, Sedum mexicanum 'Acapulco Gold', also established well with black weed mat and paper mulch, although a sawdust mulch was particularly suitable. The frost-prone Polygonum capitatum, which regrows readily from seed, did best with soil kept bare by hand-hoeing or selective herbicides, although the paper mulch also rated well. Thus the best weed control strategy varied depending on the characteristics of the ground cover being established. Other considerations, including relative costs, are also discussed.

Keywords: ground cover plants, establishment rate, weed control, herbicides.
