I will always recommend mulch over woodchips and stones in the garden.
The reason I do this is because mulched gardens are healther and more weed free. Mulched gardens are also more drought resistant so you will spend less time watering your gardens, weeding them and fighting pest problems.
I recommend black mulch for gardens and I am prepared to come and give you a quote to help improve your gardens.
Gardens also look wonderful when we lay the mulch for you.
