Why use lawn fertilizer without phosphorus around lakes or streams?
A: Much of the phosphorus (phosphate) you apply actually runs off the lawn before penetrating the soil. That means it gets into the lake causing problems. What's more, increased boating traffic keeps phosphorus stirred, preventing natural elimination. Some states now ban use of fertilizer containing phosphorus near lakes, streams or ponds.
How do I know there's no phosphorus in my fertilizer?
A: Check the second number on the package formula. 15--0--10, for example, means zero phosphate. These are always listed in this order.
Does my lawn need phosphorus?
A: No. Most soil provides all the phosphorus your established lawn needs. Actually, adding nitrogen promotes a thick, health lawn and decreases run-off because it decreases soil erosion. Two benefits in one.
How does phosphorus damage a lake, stream or pond?
A: Phosphorus encourages a heavier algae bloom and stimulates other aquatic plants, especially unwanted varieties like Eruasian Watermilfoil that can choke a lake, and, is quite difficult to eradicate. So, if your lake has a noticeably heavier "weed" growth it's likely due to too much phosphorus from run-off.
What's the best way to use a no-phosphorus fertilizer?
A: Follow the instructions on the package, and, don't be afraid to use somewhat LESS than is recommended. Because instructions are meant for a wide variety of conditions, it's usually not necessary to use more than 75% of the application rate.
When should I feed my lakeside lawn?
A: Try using a schedule based upon major holidays: 1) Memorial Day. 2) July 4th. 3) Labor Day. 4) Halloween.
What are some other things I should avoid on my lake lawn?
Avoid letting fertilizer wash off the turf.
Don't fertilize when the soil is saturated.
Avoid getting fertilizer on driveways, sidewalks, storm drains.
Above all, fertilize carefully. Don't let your fertilizer application get into the lake, stream or pond.
Use a mulching mower to leave the grass clippings on the turf.
Cut no more than the top third of the grass.
If I want to use nitrogen, what's recommended?
A: Apply about one pound per 1,000 square feet of turf area. In shade, use half that amount.
Why use nitrogen?
A: Turf needs added nitrogen because nitrogen is unstable. What the plant does not quickly use is lost.
NOTE: The above is presented in general terms. For more specific information, consult your local landscape or soil conservation professional.
