Hi - I'm a newbie to this site. Hopefully someone will have an answer to this question: I spread corn gluten meal on my lawn this spring. I had planned to overseed in the spring, then realized that the corn gluten meal would prevent my grass seed from germinating! Unfortunately, my lawn is full of weeds (which I am hand picking!) & seems thin & sad! I would like to add compost & overseed the lawn to improve its health. Do I have to wait till the fall or next year to do this, or can I overseed now? I live in the Prairies in Canada: it's hot & sunny thru most of July & some of August (zone 3).

Preen Vegetable Garden Weed Preventer contains 100% corn gluten meal. They recommend application every 4 weeks. When I was using it, I could go a week or two longer before I would notice new weeds sprouting.
I do believe I read that corn gluten meal builds up in the soil, so more applications would create a longer application time.
If I were you I would test a small patch and see how it does. I would think you would know within a week to 10 days if your seed is going to germinate.
On the border of Zones 5 & 6 on the last 2 acres of what was once a large farm. Flat, flat and more flat!
After burning through the drip stuff and the french press stuff, Paul has the last, ever, coffee maker. Better living through buying less crap.
