Question: I’ve been planning to over-seed my lawn, but according to the weather forecast, it’s going to rain. Should I wait or is it okay to go ahead and put down the seeds before it rains?

Answer: The answer to your question depends on whether you’re expecting only light rain or torrential/heavy rain. If only light rain, then it’s a good time to over-seed your lawn. Light rain will make the soil wet allowing for good seed-soil contact necessary for germination.
On the other hand, if you plant grass seeds and a big storm blows over, you’ll lose a lot of the seeds. Not only can heavy rain wash away the seeds, the remaining seeds that get soaked in pooling rain water will likely rot.
Ideally, you should till the yard first allowing the seeds to get into the soil instead of covering the top of the soil. You can also spread some topdress over the seeds to protect them. This will help with the germination and also help soak up some of that rain.
