Common Weeds in New Jersey

1. Crabgrass (Digitaria)

Definition and Appearance: Crabgrass is a common sight in many New Jersey lawns. This annual grassy weed has a light green color and grows in a star-shaped pattern. It thrives in hot, dry conditions and quickly invades thin and undernourished lawns.

Problems: Crabgrass outcompetes your lawn for nutrients, water, and sunlight, leading to sparse and unhealthy grass.

Home Solutions:

  • Maintain a healthy, thick lawn to prevent crabgrass seeds from germinating.
  • Apply a pre-emergent herbicide in early spring.
  • Hand-pull crabgrass when it appears.

2. Dandelion (Taraxacum officinale)

Definition and Appearance: The dandelion, with its bright yellow flowers and fluffy seed heads, is a perennial weed. It’s easily recognizable and can grow in any soil type.

Problems: Dandelions can overrun a lawn or garden, depleting nutrients and water from other plants.

Home Solutions:

  • Regular mowing before the dandelions seed.
  • Hand-pulling or using a specialized weed removal tool.
  • A natural herbicide like vinegar can be effective.

3. Canadian Thistle (Cirsium arvense)

Definition and Appearance: This perennial weed has spiny leaves and purple flowers. It’s notorious for its deep root system, which makes it hard to eliminate.

Problems: Canadian thistle spreads rapidly and can take over large areas of your garden or lawn.

Home Solutions:

  • Consistent mowing to prevent flowering and seeding.
  • Applying a post-emergent herbicide designed for broadleaf weeds.
  • Repeated hand-pulling to weaken the root system.

4. Clover (Trifolium)

Definition and Appearance: Clover is a perennial weed, often with three-lobed leaves and white or pink flowers. It tends to favor compacted, low-nutrient soils.

Problems: While clover can be beneficial for soil health, it can overtake lawns and create an uneven look.

Home Solutions:

  • Improve soil quality to discourage clover growth.
  • Regular mowing to prevent seeding.
  • Use of a selective broadleaf herbicide.

5. Nutsedge (Cyperus species)

Definition and Appearance: Nutsedge, often mistaken for grass, is a perennial weed with a triangular stem and yellow-green color. It grows faster and taller than most grasses.

Problems: Nutsedge can be difficult to control once established and can overtake a lawn or garden.

Home Solutions:

  • Improve drainage as it prefers wet conditions.
  • Hand-pull or dig out, ensuring removal of underground tubers.
  • Use a specialized nutsedge herbicide.

6. Broadleaf Plantain (Plantago major)

Definition and Appearance: Broadleaf plantain is a perennial weed with wide, oval leaves and a tough, fibrous root system. It often grows in compacted soils along paths and in lawns.

Problems: It can quickly spread and is resistant to mowing, making it a persistent nuisance in lawns and gardens.

Home Solutions:

  • Regular aeration of the soil to reduce compaction.
  • Hand-pulling or digging out the weed, including roots.
  • Application of broadleaf herbicides if necessary.

7. Chickweed (Stellaria media)

Definition and Appearance: Chickweed is an annual weed characterized by its small, star-shaped white flowers and delicate, oval leaves. It thrives in cool, moist conditions.

Problems: It spreads rapidly, covering large areas and competing with other plants for nutrients.

Home Solutions:

  • Mulching garden beds to prevent chickweed growth.
  • Hand-pulling or hoeing in garden areas.
  • Post-emergence herbicides can be effective.

8. Purslane (Portulaca oleracea)

Definition and Appearance: Purslane is an annual succulent with fleshy leaves and stems that can be reddish. It often grows in clusters in disturbed soils, gardens, and lawns.

Problems: Purslane can produce a high number of seeds, which can remain viable in soil for years, making it a recurrent problem. This is one of the most common weeds in NJ that we see.

Home Solutions:

  • Early removal before it seeds.
  • Cultivation or hoeing in garden beds.
  • Pre-emergent herbicides in areas with a history of purslane.

9. Bindweed (Convolvulus arvensis)

Definition and Appearance: Bindweed is a perennial vine with trumpet-shaped white or pink flowers. It’s notorious for its twining habit and deep root system.

Problems: Bindweed can strangle other plants and is challenging to remove due to its deep roots and extensive growth.

Home Solutions:

  • Regular pulling or cutting back to deplete energy reserves.
  • Applying a systemic herbicide carefully to avoid affecting other plants.
  • Mulching heavily to prevent sunlight from reaching the weed.

10. Spotted Spurge (Euphorbia maculata)

Definition and Appearance: Spotted spurge is an annual weed with a prostrate growth habit, small leaves with a reddish spot, and a milky sap.

Problems: It forms dense mats that smother other plants and is particularly invasive in hot, dry areas.

Home Solutions:

  • Pulling by hand before it seeds, with gloves to protect against the sap.
  • Mulching to prevent its seeds from germinating.
  • Pre-emergent herbicides in areas prone to spurge.
