Ranking factors for difficult weed

Root system

The depth, spread, and type of root system a weed has can make it more difficult to remove. Deep root systems can extend far into the soil, making it harder to uproot the entire plant. Some weeds have rhizomes or stolons, which can quickly spread and create new plants even from small root fragments left in the soil.
Reproduction capabilities

Weeds that produce a large number of seeds or can reproduce quickly through vegetative propagation can be harder to control. Seeds can remain dormant in the soil for many years before germinating, making it challenging to eradicate the weed population completely.
Seed dispersal mechanisms

Weeds that disperse their seeds through wind, water, or animals can spread more rapidly over a large area. This can make it harder to control these weeds, as they can quickly reappear from neighboring areas, even after being removed.
Resistance to herbicides

Some weeds develop resistance to common herbicides, making chemical control methods less effective. This can force applicators to use higher doses, alternative herbicides, or multiple applications to achieve the desired results.
Adaptability

Weeds that can easily adapt to a wide range of environmental conditions (soil type, light, water availability, etc.) will be more difficult to eradicate. They can quickly establish themselves in various landscapes and survive under different management practices.
Growth cycle

Weeds with a short growing cycle can produce multiple generations in a single season, making it harder to control their population. Perennial weeds that regenerate from root systems or other vegetative structures can also be difficult to eliminate, as they may resurge even after above-ground plant parts have been removed.
Impact on the ecosystem

Weeds that create dense mats or have allelopathic effects on other plants can quickly outcompete native vegetation, leading to a reduction in biodiversity and increased soil erosion. These types of weeds can be harder to control, as they may require more intensive management efforts.
Economic and aesthetic consequences

Some weeds have a negative impact on agricultural productivity or landscape aesthetics. The cost of controlling such weeds or the potential income loss from not controlling them can be significant, adding to the challenge of their management.
Legal and social factors

Certain weeds are classified as noxious weeds, invasive species, or pests by local or national governments, requiring specific control measures. Social factors, like the weed's use in traditional medicine or cultural practices, may hinder control efforts.
Available control methods

The effectiveness and feasibility of available weed control methods (mechanical, chemical, biological, cultural) play a significant role in determining how difficult it is to eliminate a specific weed. The availability and cost of these methods also affect the overall effort required to manage a weed population.

More information on most difficult weed to get rid of

When it comes to getting rid of weeds, there are a few commonly known species that can be quite challenging. However, according to many gardeners and lawn care professionals, the most difficult weed to eliminate is the perennial weed known as bindweed (Convolvulus arvensis). Bindweed has an extensive root system that can reach up to 10 feet deep in the soil, making it difficult to remove entirely. It also has long, twining stems that can wrap themselves around other plants, causing damage and making it even harder to control. Additionally, bindweed produces tiny white or pink funnel-shaped flowers that look pretty but are a sign of a mature plant that's producing even more seeds. Other tough weeds to get rid of include Japanese knotweed, which can grow through concrete and cause structural damage, and quackgrass, which spreads via its extensive root system and can take over entire lawns. But for many gardeners, bindweed remains the ultimate challenge in the battle against weeds.
