Thats a good question, I wondered about that myself. Yes you can spread it by hand the same day, the same hour that you seed. Bill Hill

Yup, you can spread it by hand, and I suppose if you have a small area that'd be fine, but I use a rotary spreader to put 50lbs of soybean meal on my approx 3700sqft of bermuda... in about 10 minutes....

Good day, Dan

But a better time to apply it would be 3 weeks prior to seeding so that the soil is prepared for the new roots.
