A courtyard, a driveway, the pavement in front of the works building: on paved surfaces, the one thing that grows reliably is what nobody ordered. For property managers and commercial owners it is a subject that comes back every year. For your firm it is a service with an unusually clear legal frame – because it is precisely on these surfaces that plant protection products are banned as a rule. Firms that explain that on their website instead of assuming it are not selling the cheapest single run, but an interval that keeps the surface in a defensible state.
Key takeaways
- On paved open-air surfaces, plant protection products may not be applied under Section 12(2) sentence 1 of the German Plant Protection Act. That ban is the starting point of every calculation, not a footnote for the brochure.
- A breach is an administrative offence under Section 68(1) no. 7 of the act. The fine can reach fifty thousand euros under Section 68(3).
- Thermal and mechanical methods need no exemption under Section 12(2), according to the Chamber of Agriculture of North Rhine-Westphalia. That is the argument for property managers who want to keep a liability question off their desk.
- For thermal methods, three to six treatment runs per year should be planned, depending on the maintenance history of the surfaces and local rainfall (Chamber of Agriculture of North Rhine-Westphalia). What you sell is therefore the interval, not the single appointment.
- Two figures make a quote calculable: the paved area in square metres and the requested interval. Clients already know both, which is why they belong in the form rather than in a second phone call.
Why the surface outside the building is a legal subject
The trigger for these enquiries is rarely the garden. It is the yard of a residential block, the staff car park, the path between the hall and the gatehouse. These surfaces are paved, they are visible, and they are judged by people who know nothing about joint widths. A property manager does not receive complaints about the state of a lawn edge, but about the courtyard that looks abandoned after two wet weeks.
At the same time it is the surface on which the simplest answer is off the table. Anyone talking about a paved surface is talking about an area where the legislator has ruled out the use of plant protection products. That is not a marginal question of interpretation, it is the standard case – and it applies to the yard of a terraced house just as much as to the depot of a logistics company.
The Chamber of Agriculture of North Rhine-Westphalia sums it up for practitioners: applying weedkillers on footpaths, driveways and other paved surfaces is prohibited in private settings as well as on yards and business premises, because of the risk of run-off into gullies or receiving waters and the resulting pollution (Chamber of Agriculture of North Rhine-Westphalia). The Federal Environment Agency tells consumers the same thing: on paved surfaces such as yards, paths and driveways, weedkillers may not be used as a rule (Federal Environment Agency).
For your firm this is good news as soon as you raise it. You are not selling an alternative to a cheaper route, you are selling the route that is open. And you are selling it to clients who already think in contracts: anyone who holds a maintenance contract for the green areas understands at once why the paved surface gets a line of its own. How such contracts come about is covered in winning grounds maintenance contracts.
The ban does not depend on the client
What Section 12 prohibits and what it allows
The basic rule sits in a single sentence of the Plant Protection Act, and it is short enough to quote verbatim on the service page. That is exactly its value: you do not have to assert anything, you can point.
Plant protection products may not be applied on paved open-air surfaces, nor on other open-air surfaces that are used neither for agriculture nor for forestry or horticulture.
Two points matter here. First, the sentence covers not only paved surfaces but also other open-air surfaces without agricultural, forestry or horticultural use – so the question of how a surface is used decides how it is classified. Second, there is a way out, but a narrow one: under Section 12(2) sentence 3 the competent authority may permit exemptions for the use of authorised plant protection products where the intended purpose is a pressing one, cannot reasonably be achieved by other means, and no overriding public interests stand in the way. Permits granted are reported annually to the Federal Office of Consumer Protection and Food Safety under sentence 4.
What happens if someone sprays anyway sits further back in the same act. Applying a plant protection product contrary to Section 12(2) sentence 1 is an administrative offence under Section 68(1) no. 7, and the fine can reach fifty thousand euros under Section 68(3). That is a ceiling, not a standard amount; the authority assesses each case. On top of that comes the personal side: Section 9(1) permits applying plant protection products and advising on plant protection only where the person holds a certificate of competence issued by the competent authority; Section 9(5) exempts four cases from that, among them the home and allotment garden sector and simple auxiliary work under the responsibility and supervision of a certified person. Certified persons are obliged to attend a recognised further training measure within a period of three years from the first issue of that certificate (Section 9(4) sentence 1).
| Case | Position under the Plant Protection Act | What to settle before quoting |
|---|---|---|
| Courtyard, driveway, car park, pavement – paved | Use of plant protection products prohibited under Section 12(2) sentence 1 | Method, interval and access; a permit question arises only for the chemical route |
| Other open-air surface without agricultural, forestry or horticultural use | Also covered by Section 12(2) sentence 1 | How the surface is actually used, because that decides the classification |
| Paved surface with an official exemption | Permit from the competent authority under Section 12(2) sentence 3, tied to narrow conditions | Who files the application, how long it takes and whether the conditions are met at all |
| Application contrary to Section 12(2) sentence 1 | Administrative offence under Section 68(1) no. 7, fine up to fifty thousand euros under Section 68(3) | Who appears as the applicator in the contract and how the work is documented |
A website is no substitute for legal advice, and it should not try to be one. What it can do is anticipate the question that comes up in the first conversation anyway, and name the provisions rather than allude to them. The same pattern carries other legal questions outdoors, for instance boundary distances for trees and hedges, which clients also look up before they call.
Four methods and what each one stands for
That leaves the methods that work without plant protection products. The Chamber of Agriculture of North Rhine-Westphalia handles them in separate sections – thermal, electrical and mechanical – and puts the same sentence in front of the thermal one and the mechanical one: for all kinds of thermal weed control on paved surfaces, and equally for all mechanical methods, no exemption under Section 12(2) of the Plant Protection Act is required (Chamber of Agriculture of North Rhine-Westphalia). That sentence belongs on the service page, because it answers the quiet worry of the property manager about being drawn into a procedure.
Hot water and hot steam
The water hits the plant at a temperature that destroys the cell structure; the growth dies off over the following days. According to the Chamber of Agriculture of North Rhine-Westphalia, the thermal methods are in principle suitable for all kinds of path surfaces. They are slow: driving and walking speeds of one to three kilometres per hour deliver good results from a single application.
Flaming and infrared
Instead of water, heat from an open flame or an infrared emitter does the work. The machines are light, need no water connection and are quickly ready for edges and small areas. With open-flame methods, and in part with infrared technology as well, the increased fire risk has to be watched (Chamber of Agriculture of North Rhine-Westphalia).
Brushes and sweepers
Rotating disc or roller brushes tear the growth out of the joint together with the root collar. What decides the success of brush systems is starting treatment in early spring, while the weeds are small and correspondingly more susceptible (Chamber of Agriculture of North Rhine-Westphalia). On sensitive surfaces the bristle material decides whether you leave scratches.
Electricity
As the machine passes over, current flows through the plant system including the root. The Chamber of Agriculture of North Rhine-Westphalia lists weed control by electric current as a more recent development alongside the established methods. On the service page it belongs as a sign that you follow the state of the art, not yet as a standard offer.
The choice is decided by the surface, the share of joints and what stands next to the area. A gravel path tolerates something different from a slab surface with tight joints, and a courtyard with a water connection is a different job from a car park without one. Firms that already explain how surface, joint and sub-base hang together, for example on the page about paving work, can pick up directly from there.
Clearing up is part of the service, not the exception
Which figures make a quote calculable
The difference between an enquiry that gets a quote the same day and one that needs three callbacks comes down to two figures: square metres and interval. In a commercial setting, clients as a rule know both already, because both are in their own paperwork. That lets you show a pricing logic on the page without miscalculating – how to do that without committing too early is covered in showing prices on your website.
- Paved area in square metres, split into yard, driveway, car park and pavement
- Surface type: block paving, slabs, concrete, bituminous surface or gravel path
- Share and width of the joints, because they decide how much growth finds room at all
- Maintenance history: when the surface was last treated and with what
- Requested interval and the months in which the surface is under particular scrutiny
- Access for the machine, water and power supply, standing space for the trailer
- Sensitive surroundings: planting at the edge, facade, parked vehicles
- Who disposes of the collected material and where it goes
These figures translate into a multi-step form. The order matters: first the trigger, then the surface, then the access. Starting with the surface type loses the property manager who cannot name it. What such a form looks like in detail is shown by the enquiry form for landscaping.

}
}One field deserves particular attention: the maintenance history. A surface with established old growth takes considerably more time on the first run than the same surface in its second year. The Chamber of Agriculture of North Rhine-Westphalia advises scheduling first treatments of such surfaces as early as the autumn, so that the number of treatments needed in the following year, and with it the cost, does not become unreasonably high. Asking that in the form lets you separate the initial job cleanly from the interval – the same separation that makes the difference between construction and maintenance visible for new-build outdoor areas.
The interval is the product, not the single run
A single run looks good the day after and looks like before again in July. That is not a shortcoming of the methods, it is their nature: they remove the growth, they do not prevent it. So the figure that carries the price is not the square metre alone, but the square metre multiplied by the number of runs in the year.
How often is stated plainly in practice for the thermal methods: three to six repeat treatment runs per year should be planned, depending on the maintenance history of the surfaces and local rainfall (Chamber of Agriculture of North Rhine-Westphalia). That range is the real negotiating space, and it is why the service works better as a contract than as a one-off order – the same logic that already carries maintenance contracts.
| Interval model | What the price covers | What it typically suits |
|---|---|---|
| Three runs per year | Spring, summer, late summer, each including collection and removal of the material | Surfaces with a well-kept history and a low share of joints |
| Six runs per year | Short gaps from spring to autumn, so smaller plants per run | Prominent surfaces, a high share of joints, locations with heavy rainfall |
| Initial job on established old growth | Considerably more effort at the first appointment, then transition into the interval | Surfaces left untouched for years |
| Single run on call | One appointment with no follow-ups; the result holds until the next flush of growth | Handover, sale or a photo appointment, not as a lasting solution |
An interval model has a second advantage that only shows over the course of the year: it fills weeks that would otherwise be quiet with plannable appointments and ties the same properties across the season. Firms that already offer winter maintenance know this effect and can hang both services on the same property list.
How the service page is put together
The page follows the same pattern as your other trade pages: trigger, legal position, methods, limits, input figures, evidence. It belongs in grounds maintenance and therefore next to the page for grounds maintenance, not in the private garden section, because the audience is a different one and searches with different words.
Trigger first
At the very top sit the situations in which somebody searches: complaints from tenants, an upcoming handover, a tender that includes maintenance work, a surface left untouched for two years. Anyone who recognises themselves reads on.
Legal position in four sentences
The ban in Section 12(2), the narrow exemption in sentence 3, the maximum fine in Section 68(3) and the point that thermal and mechanical methods need no exemption. No more is needed here, and less is not enough.
Methods with limits
Four short blocks for hot water, flaming, brushing and electricity. For each method one sentence on when it does not fit. Experience suggests that builds more trust than four benefit lists side by side.
Make the interval visible
A small table with three, with four to five and with six runs, plus one line each on what the model is meant for. A reader who grasps that a decision is being made calls with a concrete question.
Input figures and form
At the end comes what you need before a figure is possible: square metres, surface type, maintenance history, access. The form asks for exactly those fields and nothing beyond them.

The page belongs in the same system as your other services and is linked from the services overview. A service that appears only in the running text of a collection page is neither found nor requested – and in a tender it does not surface at all.
Evidence, photos and what counts after the run
Weed control has a presentation problem: the result is unremarkable. Nobody notices a clean joint, an overgrown one gets noticed at once. So the service lives on the direct comparison, taken from the same standpoint, at the same focal length and in comparable light.
- The state before the first run, with a fixed reference point in the frame – a post, a gully or a kerb
- The same frame immediately after the treatment
- The same frame two weeks later, once the treated material has been removed
- A picture of the collected material, so the disposal stays traceable
- A record sheet per appointment: date, area, method, weather, duration
- A yearly overview of the planned and the completed runs
These pictures are at the same time the material for the website. The discipline is in the framing: two photos from different angles prove nothing, they merely show two surfaces. What matters here is set out in showing before and after properly.
Three or four such pairs make a property sequence that carries more than any list of machines. It belongs in the portfolio gallery, together with a note on what kind of surface it was and on what interval it is maintained. The record sheet stays internal, but it is the basis for the figure you put into the next quote.
In the end weed control is a trade like paving: it has a trigger, a legal frame, a handful of methods and one figure that holds everything together. Running it as a page of its own instead of a line in the maintenance contract brings enquiries from people who already know what they want to ask. How these pages work together in the overall structure is shown by the website for landscapers.
