Should you use fertilizer on a dormant lawn? The short answer is no; fertilizing a dormant lawn is generally not recommended. During dormancy, grass is not actively growing, so it cannot effectively absorb nutrients from fertilizer. Instead, focus on fertilizing during the active growing seasons to promote healthy growth.
Why Is My Lawn Dormant?
Lawn dormancy is a natural process where grass temporarily stops growing to conserve energy and resources. This typically occurs during extreme weather conditions, such as hot, dry summers or cold winters. During these periods, grass may turn brown and appear dead, but it is usually still alive and will resume growth once conditions improve.
Types of Dormancy in Lawns
- Summer Dormancy: Occurs during hot, dry weather. Warm-season grasses like Bermuda and Zoysia are more prone to this.
- Winter Dormancy: Happens in cold weather. Cool-season grasses like Kentucky bluegrass and fescue are commonly affected.
When to Fertilize Your Lawn
Fertilizing your lawn at the right time is crucial for maintaining its health and appearance. Here are the best times to apply fertilizer based on grass type:
Fertilizing Cool-Season Grasses
- Early Spring: As temperatures rise, apply a nitrogen-rich fertilizer to encourage growth.
- Late Summer: Fertilize to repair summer stress and prepare for fall growth.
- Fall: Apply a slow-release fertilizer to support root growth before winter.
Fertilizing Warm-Season Grasses
- Late Spring/Early Summer: Once the grass is fully green, apply fertilizer to support vigorous growth.
- Mid-Summer: A light application can help sustain growth during peak season.
- Early Fall: Fertilize to strengthen the lawn before winter dormancy.
What Happens If You Fertilize a Dormant Lawn?
Applying fertilizer to a dormant lawn can be wasteful and potentially harmful. Here’s why:
- Nutrient Runoff: Without active growth, grass cannot absorb nutrients, leading to runoff that can pollute waterways.
- Weed Growth: Fertilizer can feed weeds, which are often more resilient than grass during dormancy.
- Soil Imbalance: Excess nutrients can disrupt soil health, affecting future grass growth.
How to Care for a Dormant Lawn
While fertilizing a dormant lawn is not advisable, there are other ways to care for it:
- Watering: During summer dormancy, water deeply but infrequently to keep roots hydrated.
- Mowing: Keep the lawn mowed at a higher height to protect the roots.
- Avoid Traffic: Minimize foot traffic to prevent stress on the grass.

What Is the Best Fertilizer for Lawns?
The best fertilizer for your lawn depends on the grass type and soil conditions. Generally, a balanced fertilizer with nitrogen, phosphorus, and potassium is ideal. Conduct a soil test to determine specific nutrient needs.
Can I Fertilize My Lawn in Winter?
Fertilizing in winter is not recommended for most lawns, as grass is typically dormant and unable to absorb nutrients. Instead, focus on fall fertilization to prepare the lawn for winter.
How Can I Revive a Dormant Lawn?
To revive a dormant lawn, wait for favorable weather conditions, then resume regular watering and mowing. Fertilize once the grass shows signs of active growth.
Should I Aerate My Lawn Before Fertilizing?
Yes, aerating your lawn before fertilizing can improve nutrient absorption. Aeration helps reduce soil compaction, allowing fertilizer to reach the roots more effectively.
How Often Should I Fertilize My Lawn?
Fertilize your lawn 2-4 times a year, depending on the grass type and climate. Follow a schedule that aligns with the grass’s active growing periods for best results.
Conclusion
In summary, fertilizing a dormant lawn is not recommended as it can lead to nutrient runoff and soil imbalance. Instead, focus on fertilizing during active growth periods to promote a healthy, vibrant lawn. By understanding your lawn’s dormancy patterns and adjusting care practices accordingly, you can maintain its health and resilience throughout the year.
