In times of increasing drought, sheep's wool has become an important soil additive in our gardens, as it can absorb about three times its own weight in water. Once fully swollen, it stores the accumulated moisture over a longer period of time and releases it only slowly, but continuously, back into its environment. And not only that, because in the course of its decomposition valuable nutrients are also released, which strengthen plant growth and roots. Prepared in handy nap form, it has another advantage: sheep's wool not only loosens the soil, improves water retention and acts as a fertilizer, but you can also use it as a natural mulch material that slows down water evaporation. And not only in garden land, but equally in frame or raised beds, as well as planters and balcony boxes. Simply put on the still damp soil after watering.
