Soil

Soil building and regenerative practice

Bodenpflege

Second spade test of the year: how has the soil structure developed over the season? Comparing with spring shows whether the measures are working.

Green manure

Sow a winter-hardy green manure: winter vetch, crimson clover or winter rye protect the soil until spring and provide organic matter.

Mulchen

Collect autumn leaves and spread them on beds as mulch – protects against frost, feeds earthworms and turns into humus by spring.
