The main choice with mulch mats is not the brand, it is the material: does it need to rot down once planting has taken hold, or does it need to stay in the ground for good? Settle that, then work out whether you are covering one tree or a whole bed, and the shortlist narrows itself.

Biodegradable, or a permanent membrane?

Coir, jute and Phoenix ‘Ecotex’ are all biodegradable weed control mats for trees, shrubs and new planting. Coir Mulch Mats and Coir Mulch Discs are needle-punched coir fibre that suppresses weeds and grass and protects the root zone from frost and drying out, then breaks down naturally, discs over a working life of around 3 years. Phoenix ‘Ecotex’ takes longer to disappear, breaking down fully over 4 to 5 years, and its brown colour blends into planting rather than standing out. Jute & Hybrid Jute matting does the same job: it suppresses weeds and holds moisture while young plants establish, then rots away in its own time.

None of that suits patios, gravel paths, block paving or driveways, where the ground is not being planted and weeds need keeping out for good rather than for a few seasons. That is a job for Ground Cover, a UV stabilised black polypropylene membrane in 90g and 100g weights. It is not on the same breakdown clock as the biodegradable mats, because it is not meant to be.

One plant, or a whole bed?

Coir Mulch Discs fit around the base of a single tree or shrub, laid one at a time as planting goes in. Coir Mulch Mats, Ecotex and jute all come as wider mats or rolls for borders and planted areas rather than single specimens. Jute is the most flexible on scale: pre-cut 50cm or 1m squares for individual plants, or 1m x 25m rolls where the area runs to a border or slope rather than a handful of trees.

Ground that will not hold loose mulch

Bark and loose mulch wash off a slope. A fixed mat does not, which is why Ecotex turns up on sloping ground where bark dressings are not practical. On a slope, or anywhere with wind or water movement, whichever mat you choose still needs pegging down while the roots establish underneath it.

Which mat for which job

  • Coir Mulch Discs: single trees and shrubs, breaks down over about 3 years, no herbicide needed.
  • Coir Mulch Mats: borders and planted beds, same biodegradable coir, domestic through to industrial scale.
  • Phoenix ‘Ecotex’: sloping ground and anywhere a longer working life, 4 to 5 years, matters more than fast breakdown.
  • Jute & Hybrid Jute: pre-cut squares for individual plants, or rolls for larger borders.
  • Ground Cover: patios, gravel paths, block paving and driveways, not planting beds.

Whichever mat suits the site, it still needs fixing down. Stakes & Pegs (GreenStake) are biodegradable, hold well even in hard ground and break down within about 18 months, so nobody has to come back and dig them out. Most of these lines are quote based rather than fixed price, so the next step is the enquiry form on the product page: say what you are mulching, roughly how much ground, and whether it is flat or sloping, and pricing comes back from there.

Frequently asked questions

Do I need stakes or pegs to hold a mulch mat down?

Yes, on any site with slope, wind or foot traffic. Stakes & Pegs (GreenStake) are biodegradable, hold well in hard ground and break down within about 18 months, so there is nothing left to dig out once planting has established.

Will a mulch mat wash off a sloping bank like loose bark can?

Coir and jute mats can lift on a steep, exposed slope if they are not pegged down properly. Phoenix 'Ecotex' is the mat most often specified for slopes, since it stays fixed where bark dressings would wash away, and its 4 to 5 year working life gives roots longer to establish before it breaks down.

How do I get a price for mulch mats?

Most of these lines are quote based rather than fixed price, since cost depends on size and quantity. Use the enquiry form on the product page and say what you are planting, how much ground is involved, and whether pegs are needed too.
