Fertilizing When Grass First Turns Green?
When lawns begin turning green in early spring, many homeowners assume it’s time to fertilize. However, green doesn’t automatically mean growth is ready for nutrient demand.
In fact, fertilizing too early can cause more harm than good.
What Happens During Early Green-Up
When Bermuda grass exits dormancy, it enters a transition phase.
At this point:
Root systems are still rebuilding.
Soil temperatures are gradually rising.
Top growth is just beginning.
Energy reserves are being restored.
The grass is focusing on recovery, not rapid top growth.
Why Early Fertilization Can Be a Problem
Applying nitrogen too soon can:
• Force excessive leaf growth.
• Divert energy away from root strengthening.
• Increase vulnerability to late cold snaps.
• Create uneven density across the lawn.
This leads to soft, fast-growing blades supported by a weaker foundation. Healthy lawns are built from the roots up.
When Is the Right Time to Fertilize?
For most Bermuda lawns in central Oklahoma, fertilization is best timed when:
• Soil temperatures are consistently above 60°F.
• Active vertical growth is clearly established.
• The lawn has received its first proper mowing.
• Frost risk has passed.
That typically falls later than many homeowners expect.
Timing Creates Turf Strength
The goal isn’t to make grass grow faster. The goal is to let it grow stronger.
Proper fertilization timing helps:
Increase density.
Improve heat tolerance.
Reduce disease pressure.
Improve summer resilience.
Strategic timing in spring affects the entire growing season.
