Eight questions to ask your lawn care provider to ensure their practices benefit your lawn and our local waterways.
Lawn Care Provider Questions
- Your lawn care practices greatly affect the health of our local waterways. The nitrogen and phosphorus found in fertilizer can run off your yard and end up in our waterways. Excess nitrogen and leads to "dead zones" - or areas with low amounts of oxygen. With little or no oxygen, fish, crabs, oysters, and other aquatic animals literally suffocate. An excess of these nutrients also fuels the growth of dense algae blooms that block sunlight that underwater grasses need to grow in order to continue providing food for waterfowl and shelter for blue crabs and juvenile fish.These blooms also cause our waterways to become discolored, smelly and undesirable for swimming and boating.
Ask your lawn care provider these eight questions from our friends at the Elizabeth River Project to ensure your yard isn’t harming local water waterways.
1. What kind of fertilizer do you apply? What proportion of this contains slow-release nitrogen?
Ideally, your lawn care provider should apply at least 50% slow release fertilizer. Organic fertilizers, such as compost and kelp (seaweed), are preferred. There are two problems with fast-release, chemical synthetic fertilizers. First, when they release their nutrients quickly, they create excessive grass-blade growth at the expense of root development. This unbalanced growth weakens your lawn. Second, quick-release fertilizers leach away without being used by grass plants, especially in sandy soils. Unused nutrients then wash into the river, contributing to harmful algae blooms.
2. How do you control your rate of fertilizer application?
Your lawn care provider should give you a description of how they calculate the amount needed based on your yard's acreage and fertilizer application rates. If they’re able to this, it increases the chances of your provider not over?fertilizing.
3. How do your recommendations reflect the specific conditions of my lawn?
In order to avoid over?fertilizing and over?watering, your lawn care company should first conduct a soil test and diagnose the needs of your specific lawn before discussing a plan.
4. Do I have warm or cool season grasses? What are the differences in terms of water and fertilizer needs?
If your company can't tell you, this should be a clue that they may not be adjusting fertilizing and watering to meet the specific needs of your yard.
5. What “green” practices do you follow when mowing?
They should leave grass clippings on the lawn to compost as natural fertilizer. Ideally, the company should also use an electric mower. Gas mowers are a surprisingly large source of air pollution, which contributes to water pollution. It’s also important to keep mower blades sharp.
6. What is your approach to weed control for my lawn?
It’s best to tolerate beneficial "weeds" such as clover. Clover is not just beautiful, it restores nutrients. If 5% of your lawn is clover, it may be enough for you to avoid adding fertilizers.
7. What alternatives to chemical pesticides will you use?
Ideally, the company should offer to sign a contract guaranteeing that chemical pesticides will not be used on your property. A company that uses toxic chemicals could cause harm to your children and pets in addition to our local waterways.
8. Does your company have a water quality improvement agreement with the Virginia Department of Conservation and Recreation’s Nutrient Management Program?
If not, consider referring them to this program where they can sign an agreement to follow green practices.
