I planted a fall cover crop last fall to loosen up our compacted yard in Sacramento, California. Currently, it's very tall, like 3 feet, and I'd like to mow it soon. But it contains winter and annual rye that has not yet gone to flower. Everything I read says wait for these species to flower before mowing.
I'm getting some seedlings ready to put in the ground and I'm wondering if there would be detrimental effects if I go ahead and mow the cover crop before it flowers?
