Home and Yard Pollutants

Storm drains in some towns have markers that read “No dumping. Drains to waterways”.  These markers are part of the public education communities are doing to help protect surface water from urban run-off pollution. Most residential areas are designed for rainwater to flow into the street and then into a storm drain. From there, it flows almost directly to a stream, river or lake, taking along what it picks up from surfaces it flows across.

In the overall “holiday” turf fertilization schedule, where Arbor Day, Memorial Day, Labor Day and Halloween are indicators of good timing for applications to cool season turfgrasses (Kentucky bluegrass, tall fescue, perennial ryegrass), early summer is a key timeframe for encouraging healthy growth.  When growing warm season turf species such as buffalograss and zoysiagrass, Memorial Day is perhaps the most important time to apply fertilizer, perhaps followed by a light 4th of July application if a lawn is thin or in need of recovery.

With a tip of the cap to National Groundwater Awareness Week, which was March 11-17, the landscape and gardening industry must do their part to prevent groundwater and surface water pollution on the properties we manage.

Weeds in the lawn will drive us crazy through the whole summer, but don’t forget about them yet. Fall is the best time to treat for broadleaf weeds, even though we don’t notice them as much now because they are done blooming for the year.

Water pollution can come from a variety of sources. Soil, grass clippings, fertilizer, pesticides, paint thinners, and motor oil can pollute water if picked up by stormwater runoff.
