How to protect timber fence when laying down mulch?

Was thinking of laying down a thick mulch layer along the my ~10m long timber backfence (to reduce amount of grass to mow and plant some native plants), and was wondering how/if I should be protecting the fence?


Worried that the mulch would be too moist, and prolonged exposure to the posts/pallings (the posts and railings are on my side of the fence) would cause it to rot faster. Should I paint any exposed area with bitumen paint (or similar), or attach something like builders plastic to the bottom of the fence?

Hi @unawarek,


Preventing the mulch from resting directly on the fence would be a good way to prevent decay. I like the idea of using bitumen paint or builders' plastic. We also have Jack 300mm x 8m Recycled Garden Edging that's designed for this purpose, and it can be secured with screws to your fence line.


Please let me know if you have any questions.
