Hi @Lawnmaster - it’s up to you on the mowing side and I’d say use your best judgement based on your grass length and the ability to get the product into the soil. The key is really making sure that the microalgae makes its way down into the soil at a depth relative to your root length—probably a good couple or so inches. We’ve set up a quick run feature that you can use to water it in once you’ve marked applied.
Rain shouldn’t matter, especially if you’re talking after application. If your soil is super dry to start, you may want to do a quick run on your zones for a minute or two to saturate your soil a bit before applying. Hope this is helpful.
