Good looking lawn. Now get busy on those myrtles. Pull away the mulch, soil and leaves-then tear off those water sprouts. Cutting them will enhance the growth while tearing them causes the plant to heal over the scar and prevents more growth. After doing that replace with compost and not mulching too close to tree. I too like that 5 blade reel mower. I wish more people would use these on their bermuda as I think rotary mowers have been death on lots of centipede lawns and even St. Augustine to a degree.
We all are merely gleaners from the masters who were here before us.
