such as Kentucky.

Establishment by Seed
• Different types of grass require different
methods.
• Early spring or fall is the best time to
establish grass.
• Use blended mixture of seeds.
• Till up soil and remove weeds.
• Spread seed.
Establishment Continued
• Rake seed in and add fertilizer. Roll grass
with seed roller.
• Cover with straw.
• WATER!!!! A LOT!!!
• Or by seed blankets and put over
prepared soil.

•
•
Establish area similar to planting seed.

Maintaining Turfgrass
• Test Soil.
• Fertilize spring, summer, fall.
• Summer fertilization can effect drought
tolerance.
• Manage weeds, disease and pests using
proper care methods.
• Mow often remove little.
• Irrigation (watering)
Mowing
• Be careful at first the grass is delicate.
• Never take more than 1/3 the height at a
time.
• Use sharp blades.
• Cool season grasses mow to 3-4 inches.
• Warm season can be mowed from 1-2
inches.
Fertilize
• Use high Nitrogen in the spring and
summer.
• Use higher potassium and phosphorus in
the fall.
• Rule of thumb 1 lb nitrogen per 1000
Square feet
Drop Spreader/Gravity
Spreader
• Acurate
• Drops straight down.
Rotary Spreader
• Faster
• Faster
Watering
• About 1” per week depending on the
weather.
• No need to water.
• Cool season grasses will brown in the
summer but will break dormancy in the fall.
• Water in the morning.
• It is better to soak the plants and water
less frequently.
Weeds/Pests/Disease
• By having healthy grass one can minimize
these without having to spray or physically
remove them.
• Fungicide: Kills fungus
• Pesticide: Kill pests
• Herbicide: Kills plants (weeds)
• Selective kill only broad leaves
• Non-selective kills all
Other Care
• Thatch: Build up of dead grass clippings.
This can be managed by proper care or
raking by hand or with a machine.
• Aerification: This takes plugs out of the soil
to give the soil pore space.
• Remove leaves in the fall or mulch them
by mowing over them several times.
