Controlling weeds in home lawn and garden

AMES, Iowa — Controlling weeds in home gardens and lawns can be a busy job for people, and Iowa State University Extension and Outreach horticulture specialists are here to answer your frequently asked questions about weed control.

How do I control weeds in my asparagus planting?

Weeds compete with asparagus for light, water, and nutrients and will reduce asparagus yield and quality if not controlled. Cultivation and hand pulling are the best ways to control weeds in an asparagus planting. Hoe or till the planting periodically in spring and early summer. Cultivate lightly to avoid damage to emerging spears. Under severe infestation or to manage larger areas, Gramoxone or Roundup can be used for weed burn-down before spears emerge. After the final harvest, Roundup could be applied directly to the weeds, strictly limiting any herbicide exposure to cut asparagus stalks.
