Depending on climate there are different things to consider when mulching. In northern Europe, for example, it’s important to remember when mulching leaves that only a small proportion of the leaves fall before the first frost, while a large part of it fall soon after. By letting grass grow a few centimetres higher than normal in the autumn, you can – for a short period – mulch more leaf remains, since the mulched remains are concealed in the somewhat taller grass.
