A thriving, green lawn begins with the right nutrients at the right time. Spring is a crucial season for fertilizing because it jumpstarts growth after winter dormancy. But not all products offer the same results. Finding the best lawn fertilizer for spring involves knowing the timing, formulation, and how it suits your specific grass type and soil.
Why Spring Is Ideal for the Best Lawn Fertilizer Application
Spring marks the awakening of your lawn. As temperatures rise and daylight extends, grass resumes active growth. Applying the best lawn fertilizer for spring during this period provides:
- Nutrient Replenishment: Soil nutrients are often depleted after winter rains and snowmelt.
- Enhanced Root Development: Spring fertilization supports root strength before summer heat stress.
- Greener, Healthier Turf: Nitrogen-rich fertilizers promote chlorophyll production, leading to lush green lawns.
YaraFert solutions like Ugarit 40-10-10 + TE provide a balanced blend of nitrogen, phosphorus, and potassium tailored to this growth phase, with added trace elements for optimal uptake.
Key Ingredients in the Best Lawn Fertilizer for Spring Growth
Spring lawn fertilizers typically focus on nitrogen-heavy blends to drive rapid blade development. However, an ideal product includes a balance of macronutrients and micronutrients:
Here’s a breakdown of essential components to look for in the best lawn fertilizer for spring:
| Nutrient | Function | Recommended Products |
|---|---|---|
| Nitrogen (N) | Leaf and shoot growth, chlorophyll production | Biofast, Ugarit 40-10-10 + TE |
| Phosphorus (P) | Root development, seedling strength | Ugarit 10-65-10, Super DKP |
| Potassium (K) | Disease resistance, drought tolerance | Ugarit K-T-S 70, Ugarit 10-10-40 + TE |
| Sulfur (S) | Aids in chlorophyll, protein synthesis | Sulphomin, Sulforex 60 + Cu |
| Micronutrients | Trace elements for enzymatic function | Sulfomix, Ugarit Multi |
Balanced NPK blends like Ugarit 27-27-27 + TE or humic-rich solutions such as Ugarit 10-0-5 + 70% Organic Matter offer both immediate and long-term benefits to your lawn’s soil biology.

How to Time the Best Lawn Fertilizer in Early Spring
Timing is everything when applying the best lawn fertilizer for spring. Fertilizing too early might waste nutrients; too late, and growth may lag.
Best practice application timeline:
- Cool-season grasses: Apply once soil reaches 50-55°F (10-13°C), typically late March to early April.
- Warm-season grasses: Wait until late April or early May when growth is evident.
Application tips:
- Use a soil thermometer to confirm temperature.
- Apply after the first mow of the season.
- Choose slow-release blends like SULPHOMIN for steady feeding.
Soil Prep Before Using the Best Lawn Fertilizer This Season
Before applying any product, preparing your lawn ensures nutrients are absorbed efficiently.
Here’s how to get your lawn ready for the best lawn fertilizer for spring:
- Test Soil pH: Ideal pH is between 6.0 and 7.0 for nutrient availability.
- Remove Thatch: Excess organic matter can block fertilizer from reaching the soil.
- Aerate the Lawn: Improves water, air, and nutrient penetration.
- Irrigate Lightly: Moist soil helps dissolve granular fertilizers.
Pairing your prep with the right product, such as CALCIMAG (with calcium and magnesium), also helps improve soil structure and nutrient mobility.

Grass Types That Benefit Most from the Best Lawn Fertilizer in Spring
Not all grasses respond the same way to spring fertilization. Here’s a look at which varieties benefit most from early nutrient application:
Cool-season grasses:
- Kentucky Bluegrass: Responds well to high nitrogen inputs like those in Ugarit 25-25-25 + TE.
- Fescues: Prefer slow-release blends to avoid excessive top growth.
- Ryegrass: Needs phosphorus-rich fertilizers for fast establishment (e.g., Ugarit 10-65-10).
Warm-season grasses:
- Bermudagrass: Thrives on balanced NPK formulations like Ugarit 40-10-10 + TE.
- Zoysia and St. Augustine: Benefit from micronutrient-enhanced products such as Sulfomix and Ugarit Multi.
These grass types can suffer from nutrient lockout if spring fertilization is skipped or poorly timed, especially in sandy or compacted soils.
