Overseeding:A step-by-step approach!

1. Mow down the lawn short (1-1.5 inches)


2. Power rake or core aerator– Seeder-slicer can also be used


3. Seed selection - http://www.hfrr.ksu.edu/doc1853.ashx



“other crop”Good or Bad

Ex. 0.5% other, end up planting 12 to 16 seeds per square

foot!!!(<0.01% good seed)



“weed seed”Mainly concerned with annual bluegrass and

orchard grass*no selective control in

home lawns*


4. SowingBroadcast spreader Drop spreader

Apply in two directions *make sure you overlap*


5. Seeding Rate•Kentucky bluegrass (2-3 lbs per 1,000 square ft)•Tall fescue (3 lbs per 1,000 square ft)

•Must have good seed-soil contact–Use a verti-cutter to cut grooves into ground.–Use a garden rake for small spots.


6. Fertility– Soil test– Apply (broadcast spreader) starter fertilizer right

after you are done seeding, before you start watering

– Lawn-starter fertilizer according to label if no soil test was conducted

– 0.5 lbs N per 1,000 square ft


7. Irrigation– Thoroughly soak seedbed to a depth of

sever inches– Gentle watering so seed doesn’t wash– Keep seed bed moist w/ frequent light

watering– After germination keep moist– As roots develop and grow deeper

water less frequent but soak more thoroughly until normal watering schedule is established.


8. Small areas– If only few areas need to be reseeded, prepare with hand

rake.– Sow– Spread thin layer of soil or work in with rake.
