The Ultimate Guide to Weed Control for Wilmington

Maintaining a lush and healthy lawn can be a challenge due to stubborn weeds. By following this ultimate guide to weed control in Wilmington, North Carolina, you can ensure that your outdoor space remains weed-free and thriving.

The key to a successful weed control strategy in Wilmington lies in understanding the types of weeds that are common here, control methods, and prevention. Effective weed control involves regular lawn care, manual removal, and natural or chemical treatments. Early detection, regular monitoring, and persistence are crucial for success.

Weed Types

The types of weed you’re battling in your yard can affect how you treat them. In Wilmington, homeowners encounter three major types of weeds: broadleaf, grass, and sedge.

• Broadleaf weeds: Wide, flat leaves, either annual or perennial. Common types include dandelion, chickweed, and wild violet.
• Grass weeds: Resembles turf grass, making them difficult to spot and control. Common grass weeds include crabgrass, goosegrass, and dallisgrass.
• Sedge weeds: Grass-like weeds with triangular stems found in moist, poorly drained areas. In North Carolina, yellow nutsedge and purple nutsedge thrive.

Weed Seasons

Weed growth is divided into summer and winter seasons. Knowing what time of year a weed germinates will determine the best solution. For example, when you’re doing your spring lawn care in Wilmington, pre-treating for warm-season weeds will help prevent them from growing in your summer lawn.

Summer Weeds

During the hot summer season in Wilmington, when the sun is shining and the temperatures are high, a variety of weeds seize this as the perfect opportunity to grow and thrive. These uninvited plants can pose a considerable challenge to the health and beauty of your lawn. 

Here are some of the most common summer weeds that may be trying to invade your Wilmington lawn.

• Barnyardgrass (Echinochloa crus-galli): This coarse, sprawling, purple-tinged annual grass weed thrives in moist soil.
• Crabgrass (Digitaria): A rapidly spreading summer annual weed  Smooth crabgrass has fewer hairs at its base than large crabgrass. It typically thrives in regularly scalped lawns or with poor watering practices.
• Cylindric sedge (Cyperus retrorsus): This is an upright perennial weed that can grow up to 20 inches high. Sedges thrive in wet soils and then spread to other areas.
• Dallisgrass (Paspalum dilatatum): A perennial grass weed, common in turfgrass, thrives in warm, moist areas. It has long, coarse leaves and forms thick clumps quickly.
• Dandelion (Taraxacum officinale): A perennial broadleaf typically found in acidic soils, this yellow flowering plant has fluffy white seeds. 
• Goosegrass (Eleusine indica): This annual grass weed is identifiable by its white center and wagon-wheel appearance. It thrives in open, thin, heavily-used turf. 
• Purple nutsedge (Cyperus rotundus): A perennial sedge weed common in warm-season turf, producing a reddish-purple seedhead and flourishing in wet or poorly-drained soils.
• Sandbur (Cenchrus): A summer annual grass weed with prickly burs. Maintaining robust turf is key to controlling it.
• Spurge (Euphorbia): This adaptable summer annual weed has green leaves, often with a maroon blotch, and may be smooth or slightly hairy. It features small pinkish-white flowers. The best time for control is late spring or early summer.
• Yellow nutsedge (Cyperus esculentus) is a perennial sedge weed known for its grass-like appearance and its preference for wet, poorly drained areas.

Winter Weeds

Winter weeds pose a unique challenge to homeowners in Wilmington. Unlike typical plants that wilt and die off during the cooler months, these particular weeds thrive in the cold weather. Many winter weeds like henbit and annual bluegrass can grow quickly, which may result in the hostile takeover of your lawn by these nuisances.

• Annual bluegrass (Poa annua): This fast-growing grass weed can quickly overrun lawns. Its growth can be encouraged by compacted soils and poor drainage.
• Chickweed (Stellaria media): A fast-growing, annual broadleaf weed with small white flowers and oval leaves. It thrives in shade and moist soils.
• Florida betony (Stachys floridana): This native perennial, also known as rattlesnake weed, has square stems and opposite leaves. It produces white to pink flowers in various habitats.
• Henbit (Lamium amplexicaule): This common winter annual weed, recognizable by its pink or purple flowers, is widespread throughout North Carolina. It can dominate lawns with its invasive growth if not properly managed.
• Wild violet (Viola papilionacea): This broadleaf winter weed can be annual or perennial and often grows in clumps. Wild violets have five-petal flowers that come in purple, white, or yellow. They bloom in early spring and summer, usually in the shade.

Why Weeds Are Growing in Your Yard

Several soil and lawn conditions can encourage weeds to grow in your New Hanover County yard. In fact, you can read the weeds in your grass to understand what your lawn is lacking. Addressing these underlying issues can help prevent weed growth and maintain a healthy lawn.

• Poor drainage: Sandy soil, such as the type found in Wilmington, doesn’t tend to get waterlogged, but if you keep water drainage off your lawn it will benefit your grass and deter weeds. For instance, sedges flourish under these circumstances.
• Compacted soil: In this region, sandy soil can become compacted due to excessive moisture or high activity. Goosegrass thrives in hard, compacted soil, persisting even when your lawn struggles.
• Shade: Certain weeds, such as wild violets, thrive in shaded areas. They flourish under trees or buildings, particularly in areas with less direct sunlight and where turfgrass struggles to grow.
• Soil pH and nutrient imbalances: Certain weeds, like dandelions, flourish in acidic soil conditions with nutrient imbalances. Testing and adjusting your soil’s pH and nutrients to the optimal range can inhibit weed growth and promote a healthy, dense lawn.
• Unhealthy lawns: Improperly maintained lawns, such as those not mowed to the correct height and with inadequate watering, are more susceptible to weed infestation. If your grass is suffering from a lawn disease or a pest invasion, it’s less able to resist weeds.

Weed Control Strategies

In Wilmington, effective weed control requires a customized approach that considers the region’s weeds and environment. This includes maintaining a healthy lawn, using manual and natural control methods, employing chemical herbicides if needed, and seeking professional services for severe infestations.

Good Lawn Care

An effective way to prevent and control weeds is through proper lawn care. This is the best way to get rid of crabgrass or sandbur in your yard, for example. Proper lawn care involves several practices that boost the overall health of your lawn, making it more resilient and less prone to weed infestation:

• Know your grass: The type of grass you have affects its care, growth, mowing heights, and fertilization needs. You can avoid common lawn care mistakes when you know what kind of grass you have.
  
  The best grasses for Wilmington‘s climate and soil are warm-season grasses like St. Augustine or Bermudagrass. These grasses are heat-resistant and thrive in the city’s sandy soil, ensuring a healthy, weed-free lawn.

• Regular Mowing: Maintaining your lawn at the correct height and mowing the right way promotes the growth of healthy grass, which can outcompete potential weeds.
  
  To alleviate stress, consider hiring a professional to cut your lawn. Lawn mowing services cost between $36 and $105, on average, depending on the yard size and terrain.

• Proper watering: Keeping a lawn well-hydrated is vital for its health and resistance to weeds. On average, a lawn needs 1 inch of water per week, either from rainfall or irrigation. How often you water your lawn depends on the soil type. For the sandy soil found in Wilmington, you may need to water up to 3 times a week
  
  Those looking to simplify lawn maintenance can save time and money by installing sprinkler systems. The cost to install a sprinkler system is around $0.60 per square foot, leading to an average total cost of $3,270. Your lawn’s size and the complexity of the system will influence the final price.

• Fertilizing: A well-nourished lawn is better equipped to compete with weeds for resources. For a healthy grass, regular applications of the appropriate fertilizer and correctly timed applications are crucial when you fertilize your lawn.
  
  The first step is to conduct a soil test. This test will determine the nutrients your soil lacks and its pH level. The results can then guide your selection of the appropriate fertilizer for your grass. In Wilmington, you can get testing done at New Hanover Arboretum for $4 or less.

• Aeration: Aeration benefits lawns by loosening compacted soil for grass root expansion, enabling efficient absorption of water, nutrients, and oxygen. It also helps control thatch, thus improving your lawn’s health and appearance. 
  
  If you know how to aerate a lawn yourself, you’ll need a lawn aerator and a willingness to exert some physical effort. The typical DIY cost ranges from $52 – $220. Professional aeration costs homeowners between $78 and $238, with the average cost being around $144.

Physical Removal

Physically removing weeds, whether by hand or using tools, is a straightforward and eco-friendly lawn care solution to weed control. This method works best on smaller infestations and is a good option to get rid of dandelions and chickweed. 

Here are a few ways to physically remove weeds:

• Hand pulling: This is the simplest method, which involves pulling out the weeds by hand. It’s most effective when the soil is moist, as it’s easier to remove the entire weed, including the root. Ensure you have your best gardening gloves on to protect your hands.
• Weed pullers: These tools make weeding easier, especially for deep-rooted ones. They remove weeds by gripping and prying or twisting them out. Manual tools like a hand weeder or weed puller reduce the discomfort of hand-pulling.
• Hoeing: A hoe is effective for cutting off weeds at ground level. It is best to use this method when the soil is dry. A scuffle hoe is ideal to remove weeds in lawns, between plants, and in tight spaces. However, your best garden hoe will do the job.

Pro tip: Dispose of your weeds so they don’t spread seeds in your yard. In Wilmington, yard waste can be picked up with your household trash. Place the weeds in a yard debris bag or 35-gallon bag. Ensure you meet the other requirements for yard waste collection and say goodbye to the weeds.

Natural DIY Control

For larger weed infestations, you can also use natural weed killers, such as vinegar or boiling water. These can be effective against broadleaf weeds like dandelion and wild violet. Another option is corn gluten meal, a natural pre-emergent herbicide that inhibits weed seed development.

• Vinegar: The acetic acid in vinegar can cause weed foliage to wither quickly, making it an effective natural herbicide. Ideally, use vinegar with a 10% to 20% acetic acid concentration to make a vinegar weed killer. Spray it directly onto the weeds on a sunny day. However, it might not destroy the roots, so repeated applications may be necessary.
• Boiling Water: Pouring boiling water on weeds is an easy homemade weed killer that can cause instant plant death. This method is useful for weeds growing in sidewalk or driveway cracks but is not suitable for lawns or gardens as it can harm desirable plants.
• Corn gluten meal: This byproduct of corn milling acts as a natural pre-emergent herbicide to prevent weed seeds from growing into mature plants. It can also be used as a natural weed and feed for lawns. It works best when used in early spring or fall before the weed seeds germinate as pre-emergents don’t work once the seeds begin to sprout.
• Solarization: This method involves covering the soil with a clear plastic tarp during the warmest part of the year. The sun raises the soil temperature to levels that kill weed seeds and many soil-borne pathogens. This is a good option before replanting a section of lawn or laying sod, as it will remove lawn grass, as well.

Chemical Control

Chemical herbicides can effectively manage stubborn or widespread weed infestations. They work either by killing the weed on contact or by being absorbed and destroying the weed from within. It’s important to follow the manufacturer’s instructions when using chemical herbicides for both safety and effectiveness.

There are two main types of herbicides:

• Pre-emergent herbicides: These are the best option and are applied before the weed sprouts, creating a barrier that prevents weed seed development and keeps your lawn weed-free. In Wilmington, use pre-emergent herbicides in early spring for summer weeds and in the fall to combat winter ones.
• Post-emergent herbicides: These are applied once weeds are visible. They control and eliminate existing weeds, promoting the health and growth of the desired plants. There are different types of post-emergent herbicides, so ensure you use one formulated for the weeds you’re trying to get rid of.

Professional Control

If DIY methods aren’t enough, consider hiring a professional lawn care service. They can provide a comprehensive weed control plan tailored to your lawn’s needs. This can be particularly helpful for dealing with stubborn perennial weeds like Florida betony or tough grass weeds like dallisgrass.

The cost of professional weed control services can vary significantly based on the size of your lawn, the severity of the weed problem, and the specific services required. For a 1/4-acre lot, the price for weed control typically ranges between $65 and $165, averaging around $100.

How to Keep Your Lawn Weed-Free

For a weed-free lawn, adopt a proactive and consistent approach. Encourage a healthy lawn that can outperform weeds through regular mowing, watering, and fertilizing. Use mulch in garden beds to prevent weed germination. If weeds still appear, manually remove them or resort to using herbicides if necessary (see How to Get Rid of Weeds in Flower Beds).

Other steps to take to control weeds in your yard:

• Regular inspections: Conduct regular inspections of your landscape to spot weeds early. This way, you can get rid of them before they spread and become harder to handle.

• Remove thatch: Thatch is a layer between the grass blades and the soil surface, composed of both dead and living organic material. A thick layer of thatch can attract pests and disease, weakening your turf.
  
  In Wilmington, it is best to remove thatch during the growing season when the grass can recover quickly. 
  • For warm-season grasses, this typically occurs in late spring to early summer. 
  • For cool-season grasses, it’s usually late summer or early fall.

• Remove fallen leaves: Excessive leaves can suffocate your grass and obstruct photosynthesis. Additionally, lawn pests and diseases can survive the winter in leaves left on the grass. Raked leaves can be used for other things. Consider shredding them for a DIY mulch or add them to one of the best compost bins.

• Leave your clippings: Instead of removing them, use grass clippings as mulch. Leaving them on your lawn will help suppress weeds.

• Mow higher: Avoid cutting your grass too short (aka scalping your lawn), as this can stress the grass and make it vulnerable to weed invasion. Never reduce the height of a grass blade by more than one-third in a single mowing session.

• Control pests and diseases: Maintaining a healthy lawn involves effective pest and disease control. Lawns stressed or damaged by pests, fungi, and common lawn diseases are more prone to weeds.

• Overseed:  Distributing fresh grass seeds on your lawn annually helps maintain its thickness and density, thereby keeping weeds at bay. You should overseed your lawn during your grass’s active growing season. 

FAQ: Weed Control

Is Clover a Weed?

Yes, clover is often classified as a weed due to its invasive characteristics and rapid spread. Yet its low-maintenance, drought resistance, and pollinator-friendly traits make it a beneficial ground cover or eco-friendly grass alternative. Furthermore, clover’s ability to fix nitrogen from the air can enhance soil health.

Can You Burn Weeds With a Torch?

Yes, you can use a torch to eliminate weeds. This technique, known as flame weeding, involves using a propane torch or another fuel-burning tool. It’s best used on young broadleaf weeds, particularly around driveways or sidewalks. Apply a short burst of heat to rupture the weed’s cell walls without igniting them.

Please exercise extreme caution when using this method. Handle the torch carefully to avoid igniting dry grass and other flammable materials. Avoid using it on windy days, and always wear appropriate clothing.

Why Are Weeds Hard to Get Rid Of?

Weeds are hard to get rid of because they are quick to absorb resources, outpacing grass, and can thrive in tough conditions, including drought and extreme heat. They also spread easily through wind, birds, and leftover seeds from the previous year.

When to Call a Pro

Maintaining your lawn is an effective way to control weeds, though it can be a lot of work. If you’d rather spend your weekends relaxing instead of mowing and battling weeds, hire a local lawn care professional. 

They can help keep your Wilmington landscape weed-free and ensure the health and vitality of your grass. This can be a beneficial long-term investment.
