Mulch is one of the simplest ways to make borders look finished and easier to look after. A layer of bark or organic mulch over the soil helps hold in moisture through dry spells, keeps weeds down and gives beds a neat, even surface.
Casey Jones prepares the borders first by weeding and tidying the edges, then lays the mulch to an even depth, so it works properly as well as looking good.
Why mulch your borders
A layer of mulch shades the soil, which slows down evaporation and helps stop weed seeds germinating. Organic mulches also break down slowly and feed the soil over time. The result is fewer weeds, less watering and healthier plants.
Getting the depth right
Mulch is usually laid around 5 to 7.5cm deep. Thinner than that and weeds come through; much thicker and it can stop water and air reaching the soil. It is kept back from plant stems and tree trunks to avoid rot.
When to mulch
Mulch works best laid on moist soil, so spring and autumn are good times. Mulching after a clearance or new planting is a good way to finish the job and protect what has been done.
