Most homeowners assume applying fertilizer makes grass grow faster, but the real secret to a lush lawn is often timing your herbicide application to kill weeds before they fully wake up. Your grass is like a sleeping giant that needs a strategic wake-up call.
Applying the Best Weeds and Feed for Spring at the right moment creates a barrier that stops invaders in their tracks. Getting the timing right is more important than which specific bag you grab off the shelf.
Key Takeaways
- Check the label for specific weed targets like dandelions or clover to ensure the product matches your local issues.
- Calculate your total square footage accurately so you do not apply too much or too little active ingredient per acre.
- Pay attention to the N-P-K ratio which dictates how much nitrogen is available to push rapid green growth this season.
- Match the product to the current weather forecast because most formulas require a morning with heavy dew for proper adhesion.
- Confirm if your grass type is sensitive to specific chemicals listed on the bag to avoid damaging your lawn instead of feeding it.

Frequently Asked Questions
How long after applying do I need to wait before letting my dog on the grass?
Most manufacturers recommend waiting until the product is thoroughly watered in and the blades are completely dry. This usually takes about 24 hours, but check the specific label instructions for the exact timeframe.
Can I spread this on a new lawn I just seeded?
Absolutely not, as these products are designed to kill young plants that aren't grass. Wait until you have mowed the new grass at least three or four times before applying any weed and feed. If you use it too soon, you will likely kill your new seedlings before they even get a chance to establish.
Should I apply this when the grass is wet or dry?
It is best to apply these products when the grass is slightly damp from morning dew. This helps the granules stick to the weed leaves, which allows the herbicidal component to work more effectively.
Is it better to use a liquid or granular product?
Granular products are generally easier to apply with a standard broadcast spreader and offer a more consistent release of nutrients. Liquids provide faster results but often require more precise application to avoid burning the lawn or missing patches entirely.
Will this kill my flowers or garden plants if it drifts onto them?
Yes, these products do not distinguish between a dandelion and your prize-winning petunias. You must be extremely careful to avoid overspray or drift near your flower beds. If you do accidentally get some on your flowers, rinse the foliage with clean water immediately to minimize the damage.
