Getting rid of weeds in flower beds starts with choosing the right method: pulling them by hand, using organic treatments like vinegar, or applying chemical herbicides for quicker results. Each option offers a way to protect your plants and keep your garden beautiful.
Weeds can quickly crowd out your flowers, competing for sunlight, water, and nutrients. A healthy flower bed needs a little extra care to stay strong, and managing weeds early helps your plants grow better through the season.
In this guide, I’ll show you practical ways to remove weeds. However, if you ever need help, LawnLove can connect you with a professional weed control expert in just a click.
Manual removal
Pulling weeds out of your flower beds by hand is simple, doesn’t require chemicals, and gives you immediate results.
Best tools for manual removal:
| Tool | Characteristics | Cost |
| Hand weeder | Looks like a screwdriver with a forked end. | $15 |
| Hori hori knife | A sharp garden knife with measurement marks on the blade. | $26 |
| Stand-up weed puller | Long-handled tool with claws or spikes at the base. | $30 |
| Garden trowel or hand shovel | Small hand shovel for digging roots. | $10 |
Weed by hand after rain or watering, as damp soil makes roots easier to pull. Use a tool to loosen the soil around the weed, then pull it from the base. Dispose of weeds properly, either in compost or a garden bag, depending on the type. Don’t leave them lying around, some can still spread seeds or reroot after being pulled.
My tip: I always carry a small hand weeder when I’m out admiring my garden. If I spot a weed, I can remove it right there. A few quick fixes now save time later.

Organic weed killers
Weeds have a way of sneaking into flower beds, no matter how often you pull them. For a chemical-free fix, try natural solutions like vinegar or essential oils.
Just know, most organic solutions don’t kill weeds as quickly or thoroughly as chemical herbicides. You will need patience and repeated applications, in all likelihood.
Vinegar
Vinegar’s acidity makes it an effective natural weed killer, especially in warm, sunny weather. For best results, use horticultural vinegar. For a vinegar weed killer recipe, mix vinegar with a little dish soap and salt.
Keep in mind that vinegar usually kills only the top of the plant, not the roots, so repeat treatments may be needed. When applying, be careful, as vinegar can damage your flowers too.
My tip: Use a small spray bottle for precision. Spray just the weeds, and use a piece of cardboard to shield nearby flowers.
Boiling water
Boiling water is one of the easiest ways to kill weeds. Just pour it directly onto the weed, and the heat will destroy the plant cells on contact. It’s especially effective on small, shallow-rooted weeds. Use it carefully around your flowers, as boiling water can damage any plant it touches. Tougher weeds may need a second treatment.
My tip: A narrow-spouted tea kettle gives you the best aim and keeps your hands safely away from the steam.
Salt
Salt dehydrates weeds and blocks nutrient absorption. A simple mix of 1 cup of salt to 1 gallon of water can be applied directly to weeds. However, use it with caution; salt can stay in the soil and prevent anything from growing there for a long time.
My tip: If you must use salt near your flower beds, apply it with a small brush directly to the leaves of the weed instead of pouring it into the soil.

Corn gluten meal
Corn gluten meal (CGM) is a natural pre-emergent that stops weed seeds from sprouting. Apply it at the right time, early spring or before the type of weed you’re fighting starts sprouting. It also adds nitrogen to the soil, which boosts your plant’s growth. CGM affects all seeds, you shouldn’t use it in areas where you’ve just planted flower seeds you want to grow.
Natural oils
Essential oils like clove, cinnamon, and peppermint oil can kill small, young weeds by drying them out. These natural oil-based products are often sold as organic weed sprays. They are non-selective, so they can harm any plants they touch.
My tip: Shake the bottle often while spraying. Natural oils can separate in water-based mixtures, and shaking ensures you’re delivering an even treatment.
Chemical herbicides
For widespread weed problems, chemicals are the most practical choice.
Allison Bailey, agriculture and natural resources agent at the University of Georgia Extension, recommends reading the herbicide label carefully. It outlines details like what protective gear to wear, which weeds the product targets, and how long to wait before re-entering the area.
Selective post-emergents
Selective post-emergent herbicides kill specific types of weeds, like broadleaf weeds or grassy weeds, without harming other types of plants. However, some flowers could still be sensitive to the chemicals. That’s why you need to double-check the product label to confirm it’s safe for your specific flowers.
My tip: Apply selective herbicide on calm, windless days. Even a gentle breeze can blow the spray onto your flowers and cause unexpected damage.
Non-selective herbicides
Non-selective herbicides kill almost anything green they touch. These are powerful and should be used with caution in flower beds. Always protect nearby flowers by covering them or using a shielded spray nozzle.
My tip: Use a piece of cardboard or a plastic shield to cover your flowers while spraying. It’s a simple trick that can save you from accidents.
Pre-emergent herbicides
Pre-emergent herbicides work by preventing weed seeds from germinating. They’re typically applied early in the season, before weeds start popping up. Some pre-emergents are safe for established flower beds, but you’ll need to check the product instructions carefully, as they can also block flower seeds if you’re planting anything new.
Targeted strategies for specific weeds
Some weeds are very persistent and require specific approaches for effective control. Take a look at the most common weeds and the best ways to manage each one.
Deep-rooted perennials
Examples: Dandelion, Canada Thistle.
Deep-rooted perennial weeds are tough because even a small piece of their root left behind can grow into a new plant. According to experts at Iowa State University Extension, hand-pulling works best when the soil is moist, making it easier to pull out the whole root. However, for bigger infestations, a systemic herbicide applied in late summer or fall can be very effective.
Creeping and spreading weeds
Examples: Ground ivy, bindweed.
Creeping weeds spread through underground stems (called rhizomes) or above-ground runners, making them difficult to remove. The University of Wisconsin Extension points out that these weeds can quickly spread and are difficult to pull up completely once they’re established.
For larger patches, selective herbicides containing triclopyr can help control them.
Persistent broadleaf weeds
Example: Thistle, plantain, purslane.
Some broadleaf weeds have thick leaves and strong roots, which make them hard to kill. Try to pull these weeds when they are young. For mature plants, apply selective herbicides during the weed’s active growth period. According to experts Quintin Johnson and Mark VanGessel at the University of Delaware Extension, combining herbicides like dicamba and 2,4-D is often the most effective way to control broadleaf weeds.
Grassy weeds
Examples: Crabgrass, foxtail, quackgrass.
Grassy weeds are tricky because they look like lawn grasses, but they are not. Anthony J. Koski, specialist and professor at Colorado State University, recommends using pre-emergent herbicides to stop annual grassy weeds like crabgrass before they even sprout.
