As spring is coming and its time to start getting things ready to grow, I have a few questions about some grasses in my yard. The first is bunny tail grass - does it need to be cut down or just cleaned of dead leaves? Second, I have some helictotrichon grasses and I understand you just clean out the old leaves and it keeps on growing, is this right or does it ever get cut down? what is the best way to clean out the dead leaves? thanks!
