Sowing time: sow the seeds of trees and shrubs. Felling time: cut timber that is meant to last.
Soil building and regenerative practice
Sow a cover crop mix: at least 5 species (legumes + grasses + brassicas + clover + deep-rooters). Mustard alone is not enough – no mycorrhiza, poor rooting!
Brew the last compost tea of the season. Soil and plants benefit especially now from the microbial boost before autumn.
Plant strengtheners instead of pesticides: horsetail tea, garlic tea or rock dust strengthen resilience naturally.
