I grow both Beautiful Edgings and Smoky Mountain Autumn. I love the color of SMA & it does very well for me. BE was a little slow but is good for e now. I always wondered if I should have gone with Big Smile instead. It is very similar.
I have seen mention of lawn fertilizer on FB. Do not remember if it was him or someone else. I need to check that out! I tried alfalfa pellets last year. Do not know if it really did anything for them. But I live with deer & bunnies and I did see an increase in them until I went back and dug it in!!
