In reply to Doug's suggestions
1. Not a serious lawn fertilizer. Garrett Juice is not a fertilizer at all but a microbe stimulant. Once they are stimulated, they need real food. And they need pounds and pounds of real food. The Thrive product provides fractions of an ounce rather than pounds and pounds. You would have to apply 8 gallons per 1,000 square feet to get a decent amount of nitrogen.
2. Mostly poultry litter. With Growing Green selling for $23 per bag, you can save a lot of money and get a better fertilizer with alfalfa pellets at $12 for a 50-pound bag.
3. Even more expensive than Growing Green for the granular product.
4. Another liquid. Apply every day according to the label or once every 3 months at a rate of 8 gallons per 1,000 square feet to get the same effect as one app of a grain like alfalfa pellets, soybean meal, or corn meal. Liquid fertilizers are just not for a lawn. There is essentially no lasting value to them.
Here is a picture of a spot fertilized with alfalfa pellets. The picture was taken a year ago and posted to another lawn forum. The spot was fertilized with alfalfa in May 2011. Note the improved color, density, and growth.
