Summer Weeds in Lawn: Common Types and Lawn Care Strategies

Summer is here, and with it comes a host of unwanted guests in our lawns - summer weeds. These pesky plants can quickly take over, stealing water and nutrients from our grass.

Some of the most common summer weeds include crabgrass, which can grow up to 6 inches tall and produce thousands of seeds per plant.

Crabgrass thrives in lawns with poor soil quality and inadequate lawn care.

Identifying summer weeds early on is key to preventing them from spreading.

Preemergence herbicides can be applied in the spring when air temperatures reach 65-70° F for four consecutive days. This will provide good control of many annual grassy weeds and is the best weapon against crabgrass and annual bluegrass.

Postemergence herbicides target visible weeds and are used primarily against broadleaf weeds, perennial grasses, and sedges. The chemicals 2,4-D, dicamba, mecoprop (MCPP), carfentrazone, and sulfentrazone are very common broadleaf herbicides for use in warm-season turfgrass lawns.

Hand-pulling weeds is another effective method, especially for summer annual weeds that have limited roots and are easy to remove. Make sure to pull out as much of the root as possible to prevent regrowth.

Summer annual weeds have three key Achilles' heels that make them easier to control: they're young, have limited roots, and are vulnerable to common herbicides. This makes them a bit easier to tackle than perennial weeds that have had time to develop deep and wide root systems.

Summer weeds can be a real nuisance, but understanding their types and behavior can help you tackle them more effectively. Grassy weeds like crabgrass emerge from seed as a single leaf with parallel veins, making them difficult to control.

Crabgrass is a particularly aggressive and hard-to-control grassy weed that grows in unsightly clumps, spreading to take over large areas of lawns. It tends to pop up in thinned-out areas of the lawn and can sneak in after a trimmer has been used.

Perennial weeds like dandelion spread by wind-blown seeds and can be the most difficult to control.

Summer weeds can be a real nuisance, but understanding their types can help you tackle them more effectively.

Grassy weeds, like crabgrass and annual bluegrass, emerge from seed as a single leaf with parallel veins.

Broadleaf weeds, on the other hand, emerge with two leaves and netlike veins, often producing showy flowers like dandelions or white clover.

Annual weeds, such as goosegrass and chickweed, germinate, grow, and die within a year, often setting seed before they die.

Perennials, like dallisgrass and white clover, grow for two or more years, reproducing from vegetative parts or spreading by seed.

Some weeds, like purple deadnettle, are winter annuals that appear in dormant lawns in early spring.

Dandelions, a perennial lawn weed, spread by wind-blown seeds.

Grassy weeds like crabgrass and annual bluegrass are notorious for taking over lawns. They emerge from seed as a single leaf with parallel veins, and can be controlled with pre-emergent herbicides applied in early spring.

Broadleaf weeds, on the other hand, have netlike veins and often produce showy flowers. Dandelion, a perennial lawn weed, spreads by wind-blown seeds and can be difficult to control.

Summer annuals like goosegrass and chickweed germinate in the fall and grow through the winter, setting seed before dying with the onset of warm weather. They can be challenging to control, especially if they've already set seed.

Perennials like dallisgrass and wild garlic reproduce from vegetative parts like tubers and rhizomes, making them the most difficult to control. Dallisgrass, in particular, can be a persistent problem in lawns.

Some common summer lawn weeds include crabgrass, which grows in unsightly clumps and spreads rapidly, and nutsedge, a grassy perennial that prefers moist areas and can grow rapidly in warm weather.

Ground ivy, a broadleaf weed, creeps over lawns with square stems and purple flowers, and can be difficult to control with repeated applications. Oxalis, another broadleaf weed, produces yellow flowers and can thrive in both shade and sun, making it a prolific seeder.

Spotted spurge, a low-growing and aggressive summer weed, grows in clumps or "mats" with red and hairy stems, and can be controlled with selective, broadleaf weed control materials.

Summer is here, and with it comes the perfect conditions for weeds to thrive. Some weeds, like crabgrass, can grow up to 1 inch per day.

To prevent weeds from taking over your lawn, it's essential to maintain a healthy and dense grass cover. According to the article, a lawn with at least 6 inches of grass height can outcompete weeds. This is because taller grass shades out weeds, making it harder for them to grow.

Regular mowing and watering can also help keep your lawn in top shape.

When you're starting a new lawn, it's essential to wait until you've mowed at least 3-4 times before applying any weed control products.

This waiting period allows the plugs to establish roots and reduces the risk of stress from chemical applications.

Always follow the label instructions for any products you use to ensure the safety and health of your new grass.

Summer is actually the worst time to apply weed control products to your lawn and garden, as temperatures exceeding 85 degrees Fahrenheit can be detrimental.

A thick lawn is your best defense against weeds, so make sure to keep up with regular mowing and watering.

Preemergence herbicides can be applied to the soil to prevent weeds from germinating, and they're especially effective against annual grassy weeds like crabgrass and annual bluegrass.

These herbicides should be applied when air temperatures reach 65-70° F for four consecutive days, which is usually around March 1 for the coastal and central regions.

Preemergence herbicides typically last for six to 12 weeks, so a second application may be necessary for season-long control.

Postemergence herbicides, on the other hand, target visible weeds and are often used against broadleaf weeds, perennial grasses, and sedges.

Some common postemergence herbicides include 2,4-D, dicamba, and mecoprop, which can be combined in products that control most broadleaf weeds.

These herbicides should be used carefully, as they can only be used on certain species of turfgrass, so be sure to read the product label.

Regular lawn care practices like mowing and watering can also help prevent weeds from taking over your lawn.

Preemergence herbicides are applied to the soil prior to weed seed germination, providing good control of many annual grassy weeds.

They are the best weapon against crabgrass and annual bluegrass, and also control some annual broadleaf weeds. Most are in a granular formulation, but some are applied as a liquid spray.

For effective control, granular and liquid preemergence herbicides should be watered into the soil with about ½ inch of irrigation immediately following application.

In the spring, preemergence herbicides should be applied when air temperatures reach 65-70° F for four consecutive days.

Postemergence herbicides target visible weeds, used primarily against broadleaf weeds, perennial grasses, and sedges.

The chemicals 2,4-D, dicamba, mecoprop (MCPP), carfentrazone, and sulfentrazone are very common broadleaf herbicides for use in warm-season turfgrass lawns.

Spot-treating is a great option for isolated weeds, but it requires precision, using a liquid herbicide with a spray tank and nozzle to apply product directly to the weed.

If you have St. Augustine or centipede grass, use an Atrazine-based product, as others may still cause damage-even when spot-applied.

If you're looking to control weeds in your lawn during the summer, it's essential to use herbicides safely and effectively. Applying herbicides above 85 degrees Fahrenheit can do more harm than good, damaging or killing your grass and plants.

Most broadleaf weeds are best treated in the spring or fall when air temperatures are between 65 and 85° F. This is because hotter temperatures can lead to turf damage.

Before using an herbicide, read the entire label and follow it precisely for rate and timing. This will help you achieve optimum control.

The ideal solution is to apply a post-emergent herbicide for cooler fall weather. However, if waiting isn't an option, spot-treat weeds using selective herbicides.

To avoid herbicide drift, don't treat weeds on windy days. This will help prevent damage to ornamental plants.

For acceptable control, repeat applications may be required. The product label will tell when to retreat the weeds.

If you must apply herbicides in the summer, be sure to follow the guidelines for using postemergence herbicides. This includes treating weeds when no rain is expected for at least 24 hours with spray applications.
