Detailed Maintenance Tips for UK Climate by Walls of Plants
A sedum living roof is a brilliant, low-maintenance way to bring greenery, biodiversity, and insulation to your building. At Walls of Plants, we design and install sedum roofs that thrive in the UK’s unique weather conditions.
A living sedum roof is a low maintenance green infrastructure option, but it is not a No Maintenance option.
While sedum plants are resilient, they still benefit from a few simple checks throughout the year to keep them looking their best.
1. Watering
Establishment phase (first 3–6 months):
-
Water 2–3 times a week during dry spells.
-
Make sure the water penetrates the substrate without pooling.
-
Avoid watering during the hottest part of the day.
After establishment:
-
Water only after 2–3 weeks with no rainfall.
-
During heatwaves, water in the early morning or evening.
-
Use a gentle hose spray — high pressure can disturb the plants or substrate.
2. Weeding
-
Inspect your sedum roof every 2–3 months for unwanted growth.
-
Remove weeds before they flower or set seed.
-
Common invaders include grass, moss, thistles, and dandelions.
-
The best time to weed is after light rain, when roots are easier to pull out.
3. Feeding
-
Apply a slow-release, low-nitrogen fertiliser in early spring (March–April).
-
Low nitrogen promotes colourful flowers instead of excessive leafy growth.
-
Avoid overfeeding — sedum thrives in lean, well-drained conditions.
-
Ask Walls of Plants for our recommended sedum feed blend.
4. Regular Inspections
-
Drainage: Keep outlets, gutters, and downpipes clear of leaves and debris.
-
Edges: Trim back vegetation growing over metal edges or flashings.
-
Substrate: Check for bare patches or erosion and top up as needed.
-
Roof membrane: Inspect after storms for any signs of damage.
5. Seasonal Care
Spring:
Fertilise, inspect for winter damage, and remove early weeds.
Summer:
Water only during prolonged dry periods — this is peak flowering season.
Autumn:
Clear fallen leaves and check that drainage is working efficiently.
Winter:
Minimal maintenance required — sedum is frost-hardy.
(Optional: leave seed heads for wildlife, or trim for a tidy look.)
6. Safety First
-
Always use proper safety equipment when working on a roof.
-
Never work alone.
-
Avoid stepping directly on plants — use crawl boards to spread your weight evenly.
