Re: Does overseeding work?
Little seed plus a little soil to barely cover.
Large scale overseed
Put your nose into the grass and take a good look.
If you can see the soil, so can the seed.
If light thatch, etc - best to aerate and then seed - consider triple aerate, tear it up, leave the plugs, they will grow too, as well as offer a home for the seed.
If heavy insulating thatch = dethatch, aerate, overseed as above.
Contact with soil required from ground surface, or from adding topdress.
do spring and fall - seed requires moist for a month - consult germination times - these vary with your seed mix of species - range is from 1 week to 3 weeks + time to establish = approx a month of moist - keep it moist not soppy wet - that's why fall is better than spring = more dew in the morning, and less evaporation
you will eventually see more new grass plants later too.
if in doubt = overseed - grass looks after itself in response to environmental conditions whether natural or imposed
overseeding puts grass where weeds would love to be - weeds require a home to grow - deny them with overseeding
investing weed spraying is a useless investment
Mow taller than most people - shades soil, moisture loss reduced from evaporation, also shades out weeds - go for 4 inches - and occasionally lower the mow height cos weed down low don't like to be mowed; return to 4 inches.
Grass likes to be mowed, weeds don't.
Do this routine every few years or as required. Thick is it. And tall is like walking on a pillow.
