Professional garden mulch
Volcanic lapillus is a volcanic granules that is rapidly replacing pine bark as a mulching and ecological herbicide for gardening in general.
It is a beautiful, vine-red colour, with granules sized between 11 to 14 millimetres. When it rains or it is irrigated, its colour becomes even more intense and ornamental.
Its uniform granulometry makes it easy to work with, reducing laying time and producing beautiful results. The microporosity of its granules ensures good thermal insulation on the one hand and, on the other, allows the storage of a good reserve of water, reducing soil dryness.
It should be used in a layer of at least 8 cm.
