A method of irrigating a plant comprising the steps of angling soil surrounding, or intended to support the plant to be irrigated, so as to create a slope 3 leading down towards the base region of the plant, and placing a substantially water-impervious membrane 5 on the slope, thereby causing water, falling wound the plant, in use, to be diverted towards the base region of the plant. The invention also provides devices (figs 3-8) adapted to perform the method comprising water-impervious membrane with one or more intended lines or areas of weakening for example a slit from a middle region to an edge or fold lines defining an angular sector. |
