Weed Control Solutions for Flower Beds, Gardens & Greenhouses
Whether you’re trying to prevent weeds or get a handle on an existing problem, we have the right product in stock. Herbicides, commonly known as weed killers, are the tried and true method for destroying these “pest plants.” You’ll find all-purpose weed killer along with weed control formulated for specific targets like crabgrass, ornamentals, broadleaf weeds and even old stumps.
Weed control products for flower beds, gardens, greenhouse spaces and landscaped areas should be selected based on the specific weed species and the level of infestation. Commercial-grade sprayers, foggers and granule hand spreaders make application simple and effective across soil surfaces. Use our collection of garden tools like rakes and hoes to directly remove weeds or clean up after a round of herbicide.
Weed Control How-To’s and Best Practices
Identify & Inspect First
Successful weed control starts with proper identification. Use a weed identification guide or library to determine the species present, then inspect the area to decide whether weeds are newly emerging or already established. Proper identification helps you choose between pre-emergent and post-emergent herbicides and apply them at the right time.
Use the Right Product at the Right Time
Post-emergent herbicides kill actively growing weeds. When applying near flowers or ornamentals, use barriers like cardboard to protect desirable plants.
Pre-emergent herbicides prevent new weeds by forming a barrier in the soil. Apply in early spring or fall before germination and follow label instructions for watering and reapplication.
For best results in flower beds and gardens, combine chemical control with mulch and hand removal rather than relying on one method alone.
Strengthen with Mulch and Proper Application
Put down fabric ground cover or apply mulch such as bark, gravel or straw to suppress weeds and retain soil moisture. Always read the product label before application, apply on calm days to reduce drift, and avoid disturbing soil after applying pre-emergent products to maintain the protective barrier.
Clean up dead weeds after treatment to help prevent disease spread and maintain a healthy growing area.

Flower Bed, Garden & Greenhouse Weed Control FAQs
What is the best product to kill weeds in flower beds?
It depends on the weed type. Post-emergent herbicides kill existing weeds, while pre-emergent products prevent new ones. Many gardeners combine both methods with mulch for long-term control.
Is October too late to spray for weeds?
No. Fall is often an ideal time to apply pre-emergent herbicides for winter weeds or post-emergent products on actively growing weeds. Always follow label directions.
When should you not use pre-emergent weed preventers?
Do not use them where desirable seeds are about to germinate, or after weeds have already emerged. Pre-emergent products prevent new weeds but typically do not kill existing ones.
