Picked this stuff up at lowes today. Got a small 33lb. bag and doing my home. It is 10,000 sq ft. It is grainular. When is the best time to apply this stuff. Bout to bower my buddys spreader and it has been off and on rainy this month, 50's & 60's temps here in Memphis. Cuts start in April and my lawn is mostly weeds and sparse with dirt areas, etc. I'm hoping to spread some of this triple 13 to green it up a little more. When should I spread it? When's the best time? Is this 33lb. bag enough for 10,000 sq ft? I know nothing about fertilizing so just need some SIMPLE responses, don't care to do anything else to the lawn other than put this down and water. It's my own yard so I don't care if it's a perfect lawn.
