If you’ve ever stared at your yard and wondered why your neighbor’s lawn looks like a golf course while yours looks like it’s been through boot camp the secret’s out. It’s not just luck. It’s the perfect combo of lawn fertilization and weed control.
Here’s the truth: fertilizing without weed control is like feeding an army of invaders. And weed control without fertilizer? That’s just starving your grass and leaving it weak. But when you combine the two that’s when the magic happens.
At Lawn Theory, we’ve spent years perfecting lawn fertilization and weed control for homeowners across Fairfax, Arlington, Reston, McLean, Leesburg, Great Falls, Falls Church, Centreville, Burke, Woodbridge, and all of Northern Virginia. As a veteran-owned company, we bring precision, discipline, and eco-friendly practices to your turf so your lawn isn’t just surviving it’s thriving.
Let’s break down why pairing lawn fertilizer and weed control is the only way to go, when to apply it, and how our team at Lawn Theory gets it done better than anyone else.
Why Fertilizer Alone Won’t Save Your Lawn
Think of fertilizer as a big buffet of nutrients. Nitrogen, phosphorus, potassium all the good stuff your grass craves. Fertilizer makes lawns:
- Greener and denser
- More resilient against drought
- Stronger against disease
But here’s the kicker: weeds love fertilizer just as much as grass does. Apply fertilizer without weed control, and you’re basically serving steak dinners to dandelions, crabgrass, and clover. Suddenly, instead of feeding your grass, you’re fattening up your weeds.

Why Weed Control Alone Won’t Cut It
On the flip side, let’s say you only apply weed control. Sure, you knock out crabgrass, clover, and chickweed. That’s great but what’s left?
Without fertilizer, your lawn has no nutrients to fuel recovery. You end up with a bare, patchy yard that looks weed-free… but also lifeless. Grass needs consistent feeding to rebuild density, deepen roots, and stand strong against future weed attacks.

The Secret: Pairing Lawn Fertilization and Weed Control
Here’s where the magic happens: when you combine lawn fertilization and weed control services near me into a single program, you create a lawn that’s:
- Thick and lush – so thick that weeds don’t even stand a chance to sprout
- Deep-rooted – making it more drought-tolerant during Northern VA’s hot summers
- Balanced – fed with the right nutrients while weeds are simultaneously kept in check
It’s like training your lawn to be a lean, green, self-defending machine.
Seasonal Schedule: When to Fertilize and Weed Control Your Lawn in Northern Virginia
Northern Virginia lawns face all four seasons, so timing matters. At Lawn Theory, we recommend a 6-step program from spring to fall.
Spring (March–May)
- Apply pre-emergent weed control to stop crabgrass before it sprouts.
- Fertilize with high-nitrogen blends for quick green-up.
Early Summer (June)
- Apply balanced fertilizer to maintain steady growth.
- Spot-treat weeds that sneak past spring pre-emergents.
Late Summer (July–August)
- Use slow-release fertilizer to avoid burning grass.
- Watch for heat-loving weeds like spurge and nutsedge.
Fall (September–November)
- Apply fertilizer high in potassium to strengthen roots for winter.
- Post-emergent weed control to kill broadleaf weeds like dandelions and clover.
Pro Tip: Fertilizing in fall is the secret weapon. It prepares your lawn to explode with growth in spring.
