Protect your waterways
Round up

Chemical Roundup set for Sept. 21

The primary pollution that gets into our creeks comes from several locations - oil dripping from cars, excess fertilizer from lawns and unwanted household chemicals poured down the stormdrain. Only rain should be going in the stormdrain as it leads directly to our waterways and creeks, untreated. To help prevent chemicals from polluting our water, Tri-County Health Department holds Household Chemical Roundups in Douglas, Arapahoe and Adams counties.

The Household Chemical Roundup is from 9 a.m. to 3 p.m. Saturday, Sept. 21, at Castle Rock Water, 175 Kellogg Court. A $25 contribution per vehicle is requested to offset the high cost of hazardous waste disposal.
Last year, the roundup events properly disposed of 398,518 pounds of hazardous waste such as gasoline, degreasers, cleaning compounds, garden chemicals, tires, batteries, light bulbs, and oil-based paint! Remember, you can dispose of dried latex (water-based paint) in the trash, or take left-over paint to any location (like Sherwin Williams) where it is usually donated and reused.

Nature doesn’t need fertilizer

Fall is time to fertilize for root health so your plants survive through the winter and spring back next year. But too much of a good thing doesn't make it better. Use fertilizer sparingly and pay attention to the nutrient amounts. The first number is nitrogen which promotes lawn blade and foliage growth. The second number stands for phosphorus, which helps root growth. The third number is potassium which helps with the absorption of trace elements.

Keep these nutrients in the landscape. Do not overwater or apply fertilizer before a rain event. Sweep all excess fertilizer back onto the landscape. Never let fertilizer, lawn clippings or fallen leaves go down the stormdrain! While it may seem like a healthy thing for our waterways to get these nutrients, it actually overwhelms them. Excess phosphorus creates algae which blocks sunlight, eats up oxygen in the water, and suffocates plants and animals that live in our watersheds. It wreaks havoc on the ecosystem and degrades water quality.

It’s all about the roots! Having a healthy foundation gives lawns, flowers and trees the best chance at being bright, colorful and strong. Healthy plants also use less water!

Learn about the importance of aeration, mulch and winter watering at the complimentary Winterization class,
