The gravel mulch we're recommending for this area of your garden is
10mm Yorkshire Cream
Decorative and functional
Mulching your soil after planting will help to keep weeds at bay and help lock in moisture, reducing evaporation and therefore watering. It also protects plants and surrounding buildings/paving from soil splash, and helps keep surrounding surfaces clean.
Not recommended directly adjoining a lawn where it may get kicked onto the lawn and ‘thrown’ by a lawnmower – we’d recommend using a paving, stone or timber edging to prevent gravel migrating onto other surfaces.
If cats are a problem, we’d recommend ordering a 14-20mm rather than a 10mm.
Never mulch borders that contain ericaious plants with limestone, as this will affect the soil pH and cause the plants to deteriorate.
Specification:
Supply and lay 40mm depth of Yorkshire Cream mulch to pre-planted border, laid directly on to the soil. Ensure no mulch falls into the plant foliage or damages plant foliage or stems during installation. Excludes membrane as not required.
We advise that weed membranes are NOT used and that mulch is laid directly over the soil. This is due to plant roots and soil requiring air. The installation of membranes can lead to stagnant soil and root rot.
