Commonly Encountered Pestsand How to Deal with ThemWeedsDandelions, Plantain, Ground ivy, CinquefoilLife Cycle: Perennial Leaf Type: Broad-leaved Non-Chemical Controls: Mow high so turf can out compete weeds. Mow flower heads to prevent seed production Chemical Controls: Spot treat with a selective post-emergence herbicide in the Spring or Fall Crabgrass, Goosegrass, Foxtails, Barnyard-grassLife Cycle: Summer Annual Leaf Type: Grassy Non-Chemical Controls: Do not aerate when crabgrass is germinating because weed seeds will be brought to the surface. Hand pull, removing at least part of the root. Use mulch layers/geotextile fabric. Cultivate and remove weeds from ground. Chemical Controls: Apply a selective pre-emergence herbicide 10-14 days before germinations in the spring (late April-early May). For crabgrass, apply up to the time the local forsythia ends bloom. Goosegrass germinates 3-4 weeks later Pineapple-weed, Yellow Wood Sorrell, Prostrate SpurgeLife Cycle: Summer Annual Leaf Type: Broad-leaved Non-Chemical Controls: Mow high to shade out germinating and emerging weeds. Use mulch layers/geotextile fabric. Cultivate and remove weeds from ground Chemical Controls: Apply a post-emergence herbicide once you see weeds; at the 2-5 leaf stage for crabgrass and at an early stage for all other grassy and broadleaf weeds. Annual BluegrassLife Cycle: Winter Annual Leaf Type: Grassy Non-Chemical Controls: Mow flower heads to prevent seed production. Correct compaction as many of these weeds are associated with that problem. Use mulch layers/geotextile fabric. Cultivate and remove weeds from ground Chemical Controls: Apply a selective pre-emergence herbicide 10-14 days prior to germination in the Fall (around September) Chickweed, Shepherd’s Purse, Yellow RocketLife Cycle: Winter Annual Leaf Type: Broad Leaved Non-Chemical Controls: Use mulch layers/geotextile fabric. Cultivate and remove weeds from ground Chemical Controls: Apply a selective post-emergence herbicide in the Spring just before lawns start to re-grow Yellow Nutsedge, Quackgrass, Nimbleweed, BromegrassLife Cycle: Perennial Leaf Type: Grassy Non-Chemical Controls: Remove clumps, including entire root system. Aim to control during the first year of growth Chemical Controls: Spot treat with non-selective herbicide. Be aware that this will kill both the weed and the turf grass as well. |
