I just planted a 40m^2 patch of that 10-day grass. I prepped the ground well, covered it with seeds, raked'em over, gave it another seed coverage, another raking and some more seeds on top of that for good measure. After that came the watering and the fertilizer solution. Therefore the patch is set to grow... My question is:
How often do I need to water it? It's regular spring weather here, sunny, no showers, but not hot yet.
