Stages of Weed Growth

The same herbicide on the same weed gives a different result depending on when in its life it is hit. Timing is not a refinement on weed control — it is most of it.

Why young is easy and seeded is too late

A young weed is small, soft, and moving water and nutrients fast. Anything applied to it gets taken up and distributed quickly, which is why a seedling dies from a fraction of what a mature plant shrugs off.

A mature weed has hardened leaf surfaces, a bigger root system, and more stored energy to survive an injury. Still controllable, but it takes more, and more of it ends up in your soil to achieve the same outcome.

A flowering weed is on a clock. Once it sets seed, killing the plant no longer solves the problem — the seed is already in the ground and it will be there for years. Bindweed seed can stay viable in soil for decades. Controlling a plant at flowering prevents one season of weeds. Missing it buys you many.

Which is why we are sometimes early

The best day to treat a weed is usually before you have noticed it. A crew turning up when the lawn looks fine is not making work — that is the visit that keeps it looking fine in July, and it uses less product to do it.

It is also the argument for a program rather than a call-out. By the time a weed problem is visible from the kitchen window, the cheap window has closed.

Spraying - Stages of Weed Growth

The following is a list of the different stages that we use to keep track of for the State of Colorado license:

None

The 'None' stage of weed growth indicates the absence of visible weeds in your landscape. This is the optimal condition, reflecting a well-maintained and weed-free environment. Our goal is to help you maintain this stage by implementing proactive weed control measures and regular monitoring.

Young succulent

The 'Young Succulent' stage of weed growth signifies the early emergence of weeds in their tender, succulent state. These weeds are in their initial growth phase and often appear as small, green seedlings.

Mature

The 'Mature' stage of weed growth indicates that the weeds have reached a more advanced growth stage, with larger leaves and a more established presence. While still manageable, addressing weeds at this stage may require additional measures to ensure effective control.

Flowering

The 'Flowering' stage of weed growth signifies that the weeds have reached the point of producing flowers or seed heads. This stage can be critical, as it indicates potential seed production, leading to more weeds in the future.

Seeded

The 'Seeded' stage of weed growth indicates that the weeds have matured and released seeds into the environment. This is a stage of concern, as it can contribute to future weed infestations.
