There's no single "best" fertilizer for killing weeds and growing grass. The best choice depends on several factors, including:
* Type of weeds: Broadleaf weeds (like dandelions) and grassy weeds (like crabgrass) require different types of herbicides.
* Type of grass: Different grasses have different needs for nutrients and herbicides.
* Soil type: Soil pH and composition affect how fertilizers and herbicides work.
* Climate: Temperature and rainfall influence how fast fertilizers and herbicides work.
Here's a breakdown of common options and their pros and cons:
1. Fertilizer with Weed Control:
* Pros: Convenient and often effective for a variety of weeds.
* Cons: May not be strong enough for stubborn weeds. Some formulas contain harmful chemicals.
* Examples: Scotts Turf Builder, Ortho Weed B Gon, Greenview Fertilizer
2. Separate Fertilizer and Weed Killer:
* Pros: Allows you to choose the best fertilizer and herbicide for your specific needs.
* Cons: Requires two separate applications.
* Examples: Milorganite (fertilizer), Roundup (herbicide)
3. Organic Fertilizer and Weed Control:
* Pros: Environmentally friendly and safe for pets and kids.
* Cons: May be less effective than synthetic options.
* Examples: Corn gluten meal (weed control), compost (fertilizer)
4. Pre-emergent Herbicides:
* Pros: Prevents weeds from germinating.
* Cons: Must be applied before weeds emerge. May not kill existing weeds.
* Examples: Preen, Scotts Halts
5. Post-emergent Herbicides:
* Pros: Kills existing weeds.
* Cons: May damage existing grass.
* Examples: Roundup, Ortho Weed B Gon
Tips for Choosing the Right Fertilizer:
* Consult a lawn care professional: They can help determine the best products for your specific lawn.
* Read labels carefully: Pay attention to the ingredients, application instructions, and safety precautions.
* Test your soil: This can help identify any nutrient deficiencies or pH imbalances.
* Start with a small area: Test a small area of your lawn before applying any product to the entire lawn.
* Follow application instructions carefully: Over-applying can damage your lawn and potentially harm the environment.
Remember:
* A healthy lawn is less susceptible to weeds. Proper mowing, watering, and aeration can help deter weeds.
* Consider alternatives to chemical herbicides. Hand-pulling, mulching, and using beneficial insects can help control weeds naturally.
By choosing the right fertilizer and weed control method, you can create a lush, weed-free lawn that will make your neighbors envious.
