In Pennsylvania, and much of the midwest and northeastern US, you should fertilize your lawn 2 to 3 times per year:
Memorial Day, Labor Day
- skip Thanksgiving for 2x year schedule.
This timing of applications is
conducive to the natural growth cycle of grasses and using the "holiday
schedule" makes it easy to remember!
real difficulty with designing your own lawn fertilization program is being able
to address the potential need for weed and insect
controls. That's why it's often simplest to use
something like a "1-2-3-4" program commonly called "weed & feed."
products with the 1-2-3-4 schedule are popular -- they usually have "everything"
included for that particular season of the year.
read and follow label instructions. Sweep fertilizer off walks and
driveways to minimize the chance of it reaching waterways and having
with an Organic fertilizer?
If you don't want to use herbicides, insecticides and chemical
fertilizer, then consider using an organic fertilizer such as the old
golf course favorite, Milorganite. Processed Milwaukee sewage sludge
has a 6-2-0 analysis fertilizer with a hardy 4 percent Iron. Other organic
fertilizers are available on the market. Overall, expect to pay more for organic
fertilizers than chemical fertilizers.
A successful lawn
fertilization program promotes vigorous growth that chokes out invasive weeds.
However, over-fertilization should be avoided since it will produce
excess thatch and contribute to the severity of many turfgrass diseases.
always best to have a well-designed and timed fertilization program, without overdoing it.
We strongly recommend beginning with a soil
test when seeking the best possible results.
