Athlumney Hall Verge

Initiated 2018

This narrow 100m+ strip of verge once hosted grass that over time became patchy, untidy, and unloved.

Our Aims

While we love seeing local flora, the site’s current look isn't quite meeting our community standards. We are treating this as a learning curve and we have been exploring new landscaping strategies to bring more balance and beauty back to the verge.

Stop the use of Weedkillers.

In an attempt to control the weeds, the Council / local residents sprayed weed killer for a number of years which compounded the issue by creating bare earth for more weeds to take hold and making matters worse.

2. Create a flowering planting area

More difficult than expected to create something with minimum maintenance and low watering requirements.

Planting Plan

Our initial intention was to sow wildflowers since they are economical over a large distance and relatively quick to sow and they can also cope better in less fertile soil. It wasn't hugely successful due to the combination of a very hot dry summer, extremely poor soil, and lack of protection from the wind coupled with the rapid run-off of rainwater means seeds struggle to germinate in place.

The idea to use herbs came from wanting to introduce longer-lasting plants that benefit pollinators in the St Martha's Bridge summer flower display. This appealed to us because we could essentially create the site by replanting these and increasing the site size year after year without incurring significant costs. Fruits, in the form of strawberries, came about as an experiment to create a trailing plant in the Bridge display. These were successfully transplanted and despite requiring more watering they have survived and multiplied.

Rosemary and thyme did better higher up in the verge than in the planters largely because of better drainage whereas chives and strawberries did better lower down and closer to the pavement because of more access to water.

Soil

The existing shallow depth of soil is contaminated with weed killer, highly compacted gravel, and lying on top of foundations for the pavement and estate boundary wall. This meant that we needed to source 6 tonnes of soil/compost which is beyond our financial abilities.

Mulch

Any exposed earth is likely to attract unwanted weed growth. Mulch such as small gravel stones does not work with sloping ground, woodchips move with the wind and need annual top-ups as they break down and decay. Weed mats are effective but look unsightly unless covered and so the search was directed to ground-cover plants and in autumn 2022 clover seeds were sown as a test.

2026 Biodiversity Verge

Moving from "high-maintenance bedding" towards a "sustainable, native-first ecological corridor"

An Ecological "Step-Stone" Verge and Native Pollinator Corridor

Tidy Towns Categorys: Nature and Biodiversity in Your Locality / Green Spaces and Landscaping / Sustainability

Project Description:

In 2026, we are transforming the wind-exposed, 0.5m wide roadside verge on Metges Road from an underutilized space into a high-impact Biodiversity Step-Stone. Recognizing the challenges of shallow soil depth and high exposure, we selected a specialist palette of native and near-native species that provide year-round interest and vital ecosystem services.

The project adheres to the All-Ireland Pollinator Plan by prioritizing native species such as Kidney Vetch (Anthyllis vulneraria)—the sole host plant for the rare Small Blue butterfly—and Bird’s-foot Trefoil (Lotus corniculatus), which supports over 130 species of invertebrates. To ensure "year-round tidy effect" and winter forage, we incorporated evergreen Winter Heath (Erica carnea) and Sea Thrift (Armeria maritima), providing early-season nectar for emerging queen bumblebees.

Sustainability & Maintenance: This is a low-intervention site. By using drought-tolerant, prostrate plants like Wild Thyme (Thymus polytrichus), we have created a living mulch that suppresses weeds naturally, eliminating the need for chemical herbicides. This project demonstrates that even the narrowest urban margins can play a critical role in Johnstown’s local ecological network.

Technical Detail: Mention that you used horticultural grit to improve drainage and native stone to create micro-habitats, as this shows a high level of horticultural planning.

Greening Our Shared Spaces: A Sustainable Approach

To ensure our local flora thrives, we are implementing a strategic planting plan focused on longevity and low maintenance. Our primary challenge is bare soil, which invites invasive weeds that outcompete our native wildflowers.

To tackle this sustainably, we are moving away from using traditional woodchippings that will blow away in the wind, instead, we will use a durable 5 - 6cm layer of natural stone chippings. This creates a permanent, wind-resistant barrier against weeds and within clusters we will host drought tollerant, biodiversity and pollinator friendly, perenial plants.

Our Planting Strategy:

Resilience First: We are selecting hardy varieties like heathers, herbs, and drought-tolerant alpine creepers and native wildflowers. These are chosen specifically for their ability to thrive in public spaces without constant supervision.
Smart Soil Placement: Since natural soil depth is limited, we will strategically place nutrient-rich soil only where it’s needed most.
Community-Minded: By choosing rugged, sustainable plants, we ensure the area looks beautiful year-round without requiring daily maintenance from volunteers.

Planting Layout

Since space is tight, follow this "Zoning" strategy:

The Edge (The "Curb Huggers"): Plant Wild Thyme and English Stonecrop right at the very edge. They will spill over the concrete slightly, softening the line without blocking the path.
The Structure (The "Mounders"): Every 1 meter, place a Sea Thrift or Winter Heath. These provide the "dots" of green that keep the verge looking tidy in the winter months.
The Fillers (The "Biodiversity Engines"): Interplant the Kidney Vetch and Bird's-foot Trefoil in the gaps. They have a softer, wilder habit.
The Focal Points: Place Lavender and Viper’s Bugloss in the dead center of the 0.5m strip. This keeps their height away from the edge so they don't look "floppy" or messy to passersby.

Pro-Tip for Navan Soil

In the Navan area, soil can sometimes be a bit "heavy" underneath the surface. When planting, mix a handful of horticultural grit into each hole. This ensures that even if we have a typical Irish wet winter, the roots of your Lavender and Thyme won't rot.

Past Performance

2023 Review

Nature has a mind of its own! While we had high hopes for the ground cover clover and the transplants from the 2022 St. Martha’s Bridge display, they haven't taken hold as expected. Instead, hardy native wildflowers have stepped in, creating a lush but somewhat overgrown environment that is currently competing with our planted herbs and fruits.

2022 Review

New Soil

Our work in 2021 to remove the use of weed killer in Johnstown by edging verges and then composting it meant that in February 2022 our first batch of reclaimed soil was spread along the verge. More soil was donated by a local resident to further extend the bank.

Spring 2021 turf cutting resulted in reclaimed soil being available in February 2022

New Edging

Since the slope started to spread soil onto the pavement edging was trailed and then applied for 60m in April 2022.

50m of edging will keep the soil off the path.

Ground Cover

Our work was noticed by staff at The Grow Shop who occasionally receive spent gardening material from past customers. They offered a few tonnes of clay LECA beads mixed with coconut husk that we could use to improve the drainage conditions for the woody herbs and use as a weed mat and mulch to conserve water and reduce future weeding work. A small section was trialed over the summer but quickly removed after it was seen that the round beads could spread onto the pavement and create a trip hazard.

A native Irish clover mix was sown over the bare section of new earth in an attempt to create a low-maintenance ground cover crop. It is hoped that this will not only prevent weeds but also flower for the pollinators throughout the growing season.

2022

Early spring saw the verge erupt in flower and colour with dandelions and chives being the most obvious. The fruit and herbs all grew well with more added in Autumn from St Martha's Bridge reaching the 60m mark.

2021

The 2021 bridge flowers increased our verge display to 30m. Chives, rosemary, strawberries, thyme, and oregano were successfully harvested and replanted creating a sensory display that flowers with minimum maintenance.

2020

Whilst our herbs grew during Covid lockdown the Council spread grass seed, Sept 2020, attempting to improve the appearance of the remaining 100m strip. This too grew in patches and ultimately without a maintenance plan it became dishevelled.

2019

We introduced perennial plants into the St Martha's Bridge summer flower planter display in 2019. During that Autumn we replanted these into the verge creating a 10m herb display that included thyme, rosemary, chives, and strawberries.

2018

We asked that weed killer use be stopped and we manually cleared the weeds and sowed wildflower seeds. The result was patchy growth with very few wildflowers perhaps due to the soil having been heavily contaminated with weed killer over the years.
