    Absolutely brilliant product. I used PlantGrow mulch on my vegetable beds this year and the difference was genuinely noticeable.

    During the hot, dry weather it helped save my pumpkins by keeping the soil beneath cool and moist, and it formed a really effective protective layer over the surface rather than allowing the soil to dry out and bake. Weed germination was also massively lower than I would normally expect, which made maintaining the beds so much easier throughout the season.

    What impressed me most was how well it seemed to do several jobs at once — conserving moisture, suppressing weeds and protecting the soil while also improving it.

    As a gardener, I’ve used plenty of different mulches over the years, but this is one I would happily use again and recommend. My pumpkins certainly approved!
