As the snow melts and the first hints of green appear in the Mid-Atlantic, every homeowner has the same question: When should I start fertilizing? Timing is everything in lawn care. Apply too early, and you waste product on dormant roots; apply too late, and weeds like crabgrass will already have a foothold. At The Mill, we’ve simplified the process with our signature 4-Step Lawn Program. By focusing on Step 1 and Step 2 during the spring months, you set the foundation for a lush, weed-free carpet of green all summer long.
Start with the Science: Why Soil Testing Matters
Before you spread a single grain of fertilizer, you need to know what’s happening beneath the surface. Applying nutrients without a plan is like taking vitamins without knowing what your body is missing.
We highly recommend starting your season with a professional soil test from The Mill. A soil test measures your pH levels and nutrient deficiencies, ensuring you don’t over-apply phosphorus or miss out on essential lime. Our experts can help you interpret your results and tailor the 4-Step Program to your specific backyard needs.
Step 1: Early Spring – Prevention and Awakening
Timing: March to mid-April (When the Forsythia blooms)
The goal of Step 1 is twofold: wake up your grass after its winter slumber and prevent crabgrass before it starts.
-
What it does: The Mill’s Step 1 (18-0-4) contains a high-quality pre-emergent herbicide combined with a balanced fertilizer. The pre-emergent creates a "shield" at the soil surface that stops crabgrass seeds from germinating.
-
Pro Tip: For an extra organic boost and a deeper green, consider an application of Milorganite alongside or shortly after Step 1. Milorganite is a slow-release, non-burning organic nitrogen fertilizer that is safe for children and pets. It adds organic matter to the soil, improving the "soil bank" while your lawn gets its initial spring "green-up."
Step 2: Late Spring – Weed Control and Root Strengthening
Timing: Late April to Early June (roughly 6-8 weeks after Step 1)
As the weather warms up, broadleaf weeds like dandelions and clover begin to rear their heads. This is the time for Step 2.
-
What it does: Step 2 (19-0-6) is typically a "Weed and Feed" formula. It targets active broadleaf weeds while providing a second dose of nitrogen to keep the grass thick and competitive.
-
How to Apply: For the best results with weed control, apply Step 2 to a damp lawn (early morning dew is perfect). This helps the granules stick to the weed leaves, allowing the herbicide to be absorbed effectively.
Application Tips for Success
To get the most out of The Mill’s 4-Step Program, follow these "Pro" rules:
-
Check the Soil Temp: For Step 1, wait until soil temperatures are consistently around 55°F.
-
Calibrate Your Spreader: Ensure your spreader is set to the specific settings listed on the bag to avoid striping or over-application.
-
Watering: While Step 1 should be watered in to activate the pre-emergent barrier, Step 2 needs to sit on the weed leaves for 24-48 hours before rain or irrigation.
