7 Overseeding: A step-by-step approach! 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)

8 Overseeding: A step-by-step approach! 3. Seed selection - http://www.hfrr.ksu.edu/doc1853.ashx “weed seed” Mainly concerned with annual bluegrass and orchard grass *no selective control in home lawns*

9 Overseeding: A step-by-step approach! 4. Sowing Broadcast spreader Drop spreader Apply in two directions*make sure you overlap*

10 Overseeding: A step-by-step approach! 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.

11 Overseeding: A step-by-step approach! 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

12 Overseeding: A step-by-step approach! 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.

13 Overseeding: A step-by-step approach! 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. Soil to seed contact
