I live on the gulf coast of south texas. My lawn is about athird of a acre. I would say it's coastal burmuda. It is nov. Now and the grass is still green about 2 1/2 inches. My gole is to have it down to about 1 to 1 1/2 inches by april. My question is. How much should I cut at a time to work it down 1 in.? When should I feed it? And should I invest in a seven blade reel mower? Thanks for any guidance.
