Soil

Soil building and regenerative practice

Green manure

Sow a cover crop mix: at least 5 species (legumes + grasses + brassicas + clover + deep-rooters). Mustard alone is not enough – no mycorrhiza, poor rooting!

Compost

Brew the last compost tea of the season. Soil and plants benefit especially now from the microbial boost before autumn.

Klimaresilienz

Plant strengtheners instead of pesticides: horsetail tea, garlic tea or rock dust strengthen resilience naturally.
