Tips & Hints
- Buy the 50 pound
bags. You get more for your money. For example, a bag might cost about
$14 versus going to the local home supplier and paying $25 for 20 pounds.
- It's better to
fertilize lightly and often instead of in heavy doses far apart. That
way the grass is stronger and holds up better.
- Water after fertilizing
or put it out just before it rains.
Mistakes to avoid
You need to water
after fertilizing. If you don't water or it doesn't rain, the grass will
burn from it.
