Frequently asked questions

When should I fertilize Kentucky bluegrass?

It is a cool-season grass, so feed in spring and again in early fall. The fall feeding is the most important — it builds roots and color that carry into next spring.

How long will one bottle last?

At 1 tsp per quart, the 8 oz bottle makes about 48 watering cans of feed. For a typical shelf of 10–15 plants fed every 1–2 weeks in season, that's several months of feeding — and the 32 oz bottle four times that.

How do I apply it to a lawn?

A hose-end sprayer set to the labeled rate covers a lawn in one pass; use a watering can for small patches. Apply in the morning or evening and water in lightly.

Why does my bluegrass go brown in summer?

Heat dormancy. Bluegrass slows in high summer and greens back up when nights cool. Do not push it with heavy feeding in the heat; water deeply and feed again in September.

Is it safe for kids and pets?

Yes once it has been watered in and the grass is dry. It contains nutrients only — no herbicides or pesticides.

Will it burn my lawn?

Not at the labeled rate. Liquid feeding spreads evenly, so you avoid the streaks and burn spots uneven granular spreading can cause. Skip application in extreme heat.

When will I see results?

Most lawns green up within one to two weeks of the first feeding; thickening builds over a few applications.
