Japanese knotweed is one of the most aggressive and invasive plants in New Jersey. Known for its rapid growth and strong root system, it can quickly take over gardens, lawns, driveways, and even building foundations. If you live in West Deptford, NJ, and are struggling with this invasive species, professional removal is the most reliable solution.

In this article, we will explain why Japanese knotweed is such a problem, the risks of ignoring it, and how our specialized knotweed removal services in West Deptford can protect your property.

What is Japanese Knotweed?

Japanese knotweed (Fallopia japonica) is a fast-growing, bamboo-like plant originally from East Asia. It was brought to the United States as an ornamental plant but has since become one of the most destructive invasive species.

Growth speed: It can grow up to 3–4 inches per day in spring.
Root system: The rhizomes (underground roots) can spread more than 20 feet horizontally and 10 feet deep.
Persistence: Even a small root fragment can regrow into a full plant.

Because of these characteristics, DIY methods like cutting or digging rarely succeed. Without proper control, knotweed will return year after year.

Why Japanese Knotweed Removal in West Deptford, NJ, is Essential

Residents and property owners in West Deptford face unique challenges with invasive plants because of the region’s soil and weather conditions. Japanese knotweed thrives here, and if left untreated, it can cause:

Property DamageKnotweed roots can grow through asphalt, concrete, retaining walls, and even building foundations.
Reduced Property ValueReal estate buyers often avoid properties with knotweed because of the high cost of removal and ongoing risk.
Landscape LossKnotweed spreads quickly and chokes out native plants, ruining gardens and green spaces.
Legal & Insurance IssuesIn some states and municipalities, property owners are required to control knotweed to prevent it from spreading to neighbors’ yards.

How to Remove Japanese Knotweed in Somerdale, NJ: Expert Advice and Local Solutions?

If you're a homeowner, property manager, or developer in Somerdale, NJ, and you’ve spotted Japanese knotweed on your land, you’re facing one of the most aggressive invasive plants in the region. Left untreated, Japanese knotweed can damage foundations, crowd out native vegetation, and spread rapidly across properties. In this post, we dive into effective removal strategies, local realities in Somerdale, NJ, and why hiring an expert is often your best bet.

Why Japanese Knotweed Is a Big Problem in Somerdale, NJ?

Japanese knotweed (often including its hybrid Bohemian knotweed) is not just an eyesore. Its underground rhizome system can spread many feet beyond visible growth and regrow from tiny fragments. ipm.cahnr.uconn.edu+2NJ.gov+2

In New Jersey specifically, knotweed is difficult to contain once it takes root. Your site in Somerdale may border wetlands, streams, or neighboring properties — all of which pose risks of further spread. The Professional Japanese Knotweed Removal Somerdale NJ service area page confirms the company handles projects throughout Somerdale and nearby townships. My Site

When knotweed creeps into cracks in pavement, undermines walls, or invades landscaping beds, the structural and financial risks grow fast. That’s why early detection and prompt treatment are key.

Proven Methods of Removal: What Works (and What Doesn’t)

There is no “one-and-done” solution for knotweed. Successful removal relies on layered, persistent treatment over time. Below are methods used by professionals and guidelines you should understand.

Mechanical / Physical Control

Cutting / mowing repeatedly: Cutting stems close to the ground multiple times per growing season reduces the plant’s ability to feed its root system. According to UConn’s guidelines, cutting in May/early June, mid-July, and late August (before flowering) is effective. ipm.cahnr.uconn.edu
Excavation of rhizomes: For severe infestations or development sites, digging out root systems entirely can work—but only if all rhizome fragments are removed. Even small bits left behind may resprout. se-eppc.org+2Ecological Landscape Alliance+2
Containment / root barriers: In some cases, installing a deep barrier to block rhizome expansion is used in conjunction with other methods.

However, mechanical methods alone rarely succeed in full eradication because of the tenacity of the underground root system.

Chemical / Herbicide Application

Foliar spray during late summer or early fall: Applying glyphosate (or a mix including triclopyr) when the plant is transporting resources downward to the roots improves uptake and damage to the rhizomes. ipm.cahnr.uconn.edu+2agriculture.nh.gov+2
Cut-stem or stem injection: After cutting the stalk, herbicide is painted or injected into the hollow stem so it moves directly into the plant’s vascular system. This method is precise and can limit drift to non-target species. se-eppc.org+3ask.extension.org+3ipm.cahnr.uconn.edu+3
Repeat treatments: Most herbicide plans span multiple years, with follow-up applications targeting regrowth. ipm.cahnr.uconn.edu+1

One observed method: injecting 41% glyphosate concentrate into stems or rhizomes has been tried—with mixed but interesting results. ask.extension.org

Integrated Approach & Persistence

Best results come when mechanical suppression and herbicide treatments are combined in a planned, multi-year program. As outlined in ecological management plans, the key is persistent, tenacious presence rather than relying on a single tactic. Ecological Landscape Alliance+1

What Makes Somerdale, NJ Unique? (and How We Adapt)

When dealing with Japanese knotweed in Somerdale, NJ, several local factors influence how removal must be handled:

Soil & hydrology: Many parts of Camden County have clay, wetlands, or seasonally saturated soils. Rhizomes can expand toward moisture sources (like drainage ditches). Removal methods must account for subsurface water tables and avoid herbicide runoff.
Proximity to neighboring properties: Knotweed can easily jump property lines. Professionals must contain disturbance and avoid sending rhizome fragments beyond the work zone.
Local regulations & permits: New Jersey environmental regulations may restrict herbicide use near water bodies or in floodplains. Always use licensed applicators and permitted products.
Access constraints: Some Somerdale lots may have fencing, steep slopes, or tight access, influencing whether excavation or chemical methods are feasible.

Because of these local complexities, a standardized one-size approach rarely works. That’s why local specialists (like your Somerdale service) begin with a site survey to tailor a treatment plan.

Why Hire a Local Expert for Knotweed Removal? (Somerdale Advantage)

Deep local knowledge: A Somerdale-based contractor understands soils, drainage patterns, and neighboring zones, reducing the risk of drift or spread.
Precision application: Experts use targeted cut-stem or injection techniques to protect surrounding plants and limit chemical use.
Regulatory compliance: Licensed firms stay current with NJ pesticide laws, wetlands rules, and disposal requirements.
Long-term guarantees and monitoring: Knotweed removal is a multi-year effort. A local firm can provide follow-up visits and track regrowth over time.
Liability & insurance: Improper removal may lead to spread onto adjacent properties. Professionals carry liability coverage and take steps to secure their work.

Step-by-Step Practical Plan for Somerdale Homeowners

Here’s a summary of what a well-executed removal plan might look like, adapted to local conditions:

Initial site assessment
Inspect the entire infestation zone, measure spread, identify sensitive features (water bodies, fences, slopes). Map out boundaries and potential pathways of spread.
Preliminary suppression
Begin cutting or mowing down to ≤ 6 inches to diminish vigor. Bag and remove all cut materials, never compost on site. ipm.cahnr.uconn.edu+1
Herbicide application during ideal window
Late summer through early fall is typically best—plants are translocating to roots, so herbicide is more effective. Use foliar spray or injection depending on stem diameter and access.
Follow-up treatments
In the next growing season(s), monitor for new shoots and retreat them. Two or more years of maintenance is often required. agriculture.nh.gov+1
Site restoration & planting
After treating, replant with native species that are competitive and suited to local conditions to reduce re-infestation pressure.
Long-term monitoring
Inspect annually (or more often) for regrowth. Take prompt action on any new shoots.

Conclusion:

If you’re in Somerdale, NJ and suspect Japanese knotweed on your property, don’t delay. Early action not only reduces cost and damage but also prevents spread to adjacent land. A professional, localized approach is usually far more effective than DIY methods pieced together.
