A living wall in a Vancouver lobby or office stays healthy when it is serviced on a predictable schedule: a quick inspection roughly twice a month, plus a deeper horticultural visit monthly or quarterly, depending on the planting and the season. Skip either one and the wall declines faster than most people expect. Below we walk through what each visit involves, where walls usually fail, what to put in writing, and how to decide between doing it in-house and hiring a service.
TL;DR
- Plan for two kinds of visits: short inspections (about twice a month) and full horticultural services (monthly or quarterly), according to our facility manager's playbook.
- Irrigation is the biggest driver of labor and cost. Closed-loop and open-loop systems need very different upkeep.
- A green wall is not "set and forget". Poor ventilation or over-wet media can turn a feature into a humidity problem.
- Keep a simple log of run times, pump and filter status and plant replacements. It protects your warranty and your budget.
- Our Greenspace+ program covers design, installation, maintenance and plant replacement for a fixed monthly fee, from $299 per month.

Why a green wall needs more than a watering can
A green wall packs dozens or hundreds of plants into a thin vertical layer. There is very little soil, very little buffer, and every plant depends on the same irrigation line and the same light. When something drifts, it drifts for the whole wall.
That is why we say maintaining a living wall is more than just a watering can. Our technicians, whom we like to call plant clinicians, watch light levels, adjust soil amendments, prune for density and check the hardware behind the foliage. Failing to do that specialized care leads to rapid decline in a dense vertical ecosystem, as we describe in our green wall maintenance playbook.
Most of the walls we are asked to rescue did not fail because of a bad plant choice. They failed because nobody owned the schedule.
The two kinds of visits: inspection and horticultural service
The most common mistake we see among facility teams is treating these as the same thing.
Inspection visits (about twice a month)
An inspection is a brief walk-through. The technician confirms the irrigation is running, looks for early stress such as yellowing, leaning or dry patches, and spots leaks before they reach drywall or flooring. It takes little time, but it catches problems while they are still cheap.
Horticultural service visits (monthly or quarterly)
This is the deep-dive. Plants are pruned, cleaned and fertilized, dead material is removed, and mechanical components such as pumps and filters are physically serviced. Whether the cadence is monthly or quarterly depends on the complexity of the planting and on seasonal growth. A dense tropical wall in a bright atrium grows faster than a sparse low-light one.
Confusing the two leads to missed maintenance and premature system failure. If a vendor tells you the wall is "checked" every two weeks, ask whether a full service happens as well, and what is done during it.
What happens at a service visit: the technician's checklist
Every wall is different, but a thorough service follows a pattern. Here is how we think about it.
- Observe first. Look at the whole wall from a distance for color variation, gaps and lean (plants grow toward light, which is phototropism).
- Check irrigation. Confirm run times, look at emitters and lines, and test for even moisture across the top, middle and bottom.
- Service the hardware. Clean filters, inspect pumps, and check the reservoir if the system recirculates water.
- Prune and groom. Remove dead leaves, trim for shape, and rotate or replace plants that are struggling.
- Feed and amend. Fertilize according to season and plant mix.
- Scout for pests. Use an Integrated Pest Management approach: look early, act on the smallest effective step first.
- Log everything. Record what was found and changed.

Irrigation: the choice that sets your maintenance bill
The choice between open-loop and closed-loop irrigation is the single biggest factor in long-term maintenance labor and cost.
| Closed-loop (recirculating) | Open-loop (drain to waste) | |
|---|---|---|
| How it works | Water recirculates through a reservoir | Fresh water passes through once and drains away |
| Main upkeep | Regular reservoir cleaning, water testing and recharge to prevent pump burnout | Annual backflow preventer testing and regular drain route inspections |
| Main risk | Pump failure, stale or imbalanced water | Clogged drains, leaks, plumbing code compliance |
| Best for | Spaces without a convenient drain | Spaces with a drain and a plumber you trust |
The upkeep details above come from our maintenance playbook. Open-loop systems need to meet local plumbing codes, so confirm requirements for your building with a licensed plumber and your property manager before you commit to one.
Overwatering is the failure we see most. A wall that looks lush but smells musty is usually too wet, not too dry. Our guide to green wall irrigation for facility teams covers how to tune run times.
If your building also tracks water use more broadly, water efficiency calculations are one way to put a number on it, though the framework in that article is written for the United Kingdom, so check what applies in British Columbia.
Light, pruning and replacement
Irrigation gets the attention, but light quietly decides which plants survive.
- Light. Measure what the wall actually receives, not what the room feels like. Vancouver's long, grey winters mean daylight-dependent walls often need supplemental lighting from late fall to early spring. If lights are installed, check them as part of every service.
- Pruning. Regular pruning keeps the wall dense and lets light reach lower plants. Overgrown tops shade the bottom rows, and bare patches follow.
- Replacement. Even in a well-run wall, some plants will fail. Replace them promptly with the same species or something better suited to that spot, because gaps invite pests and weeds.
- Structure. Periodically inspect the frame, panels and anchoring, and look for moisture on the wall behind.
This is also where a guarantee matters. With Greenspace+, plant replacements are part of the monthly fee and our plants come with a healthy plant guarantee, so a failed plant is our problem, not a surprise line on your invoice.
Air quality, humidity and the "set and forget" myth
Green walls are often sold on air quality, and there is research behind some of the benefits. A study of a living wall in an actual workplace reported a 3°C to 5°C cooling effect and a 5% to 50% drop in CO2 in the room, with an estimated 20% energy saving. Those are results from one study of one wall, so treat them as encouraging rather than a guarantee for your space.
The caution is just as important. University of British Columbia research on interior living walls and indoor air quality points to the need to manage bioaerosols and integrate ventilation properly. A well-maintained wall adds to a healthy space. A neglected one can contribute to mold or humidity problems. That is the practical reason a wall should never be treated as set and forget.
What that means day to day:
- Keep growing media damp, not soggy.
- Remove dead and decaying plant material quickly.
- Make sure air can move around the wall.
- Report musty smells, visible mold or condensation on nearby surfaces right away, and involve your HVAC contractor if the room feels humid.
If anyone in your space has asthma, serious allergies or a compromised immune system, talk with your building's health and safety lead before installing a wall, and ask your service provider about their prevention routine.
Keep a log: your insurance policy
Documentation is the most overlooked part of green wall care. A simple, consistent record of irrigation run times, pump and filter status, and plant replacements gives you a paper trail for warranty claims and budget reviews. Without one, it is hard to prove service was done or to spot a pattern, such as the same pump failing every spring.
A one-page log is enough. Record:
- Date and who attended.
- Visit type (inspection or horticultural service).
- Irrigation run times and any changes.
- Pump, filter and reservoir status.
- Plants replaced, and where.
- Issues flagged for the building or property manager.
Ask any provider to share this log after each visit. We do it as a matter of course.
In-house or a service: how to decide
Some buildings have a capable facilities team that can handle watering checks. Most still bring in a specialist for the horticultural visits. Use these questions:
- Does anyone on staff know plants, pruning and pest scouting, or only the building systems?
- Who covers vacations and holidays? A wall can decline in two weeks.
- Who is accountable if plants fail, and is replacement included or billed separately?
- Do you want predictable monthly costs or project-based billing?
The services you will meet in Vancouver generally fall into three types: landscaping crews who add interior work on the side, specialist living wall installers, and full-service interior plant companies. Ask each type about visit frequency, the guarantee, replacement terms and whether they keep a service log. Do not accept a quote that lists only a price per visit.
What it costs
Green wall costs vary a lot with the system, wall size, plant density and irrigation type, and quotes should be tailored to your site. We do not publish a per-square-foot price for walls. What we can say plainly is that our Greenspace+ plan starts from $299 per month, with no upfront cost and no long-term commitment, and that a wall is scoped individually. Treat any figure you read online as a rough range, then ask for a written quote.
Our perspective: plan the maintenance before the wall
We would rather talk about maintenance before a wall is designed than after. The best green walls we have seen were specified with the service visit in mind: access to the irrigation controls, a drain where one is needed, lighting that matches the plant palette, and a clear owner for the log.
The worst outcomes follow a familiar story. A wall is installed for a launch, the budget stops at installation, and nobody is assigned to it. By month four the top rows are overgrown, the bottom rows are bare, and someone is asking whether living walls are worth it. They are, when they are cared for. The wall was never the problem. The missing routine was.
So our advice is simple. Pick an irrigation approach you can sustain. Put both visit types in writing. Insist on a log. And choose a provider who stands behind the plants. If you do those four things, a living wall can stay a highlight of your space for years.

FAQ
How often should a commercial green wall be serviced?
Expect a quick inspection about twice a month and a deeper horticultural visit monthly or quarterly, depending on the complexity of the planting and seasonal growth. The exact rhythm should be written into your agreement. Dense, bright, fast-growing walls sit at the monthly end.
Can I maintain a green wall with my own facilities staff?
You can handle basic checks, such as confirming that irrigation is running and spotting leaks, if your team is trained. Pruning, fertilizing, pest management and pump or filter servicing usually benefit from horticultural expertise. Many buildings split the work this way.
Why is my green wall turning yellow or brown?
Common causes are overwatering, uneven irrigation, too little light and clogged emitters. Check the pattern first: yellowing at the bottom often points to too much water, while dry tops suggest an irrigation fault. If you cannot find the cause quickly, have a horticulturist look at it before the problem spreads.
Do green walls cause mold?
They can if they are kept too wet, poorly ventilated or left with dead plant material. Research on interior living walls highlights bioaerosols and ventilation as things to manage. Regular expert maintenance and good airflow keep the risk low.
