Dosierung

2-4 Düngungen pro Jahr. Frühling: stickstoffbetont für Wachstum. Sommer: ausgeglichen. Herbst: kalibetont für Winterhärte. 30-50 g/m² pro Düngung. Für 200 m²: 6-10 kg pro Durchgang. In Deutschland beliebt: Wolf-Garten, Compo und Substral.

Organisch vs. Mineralisch

Organisch (Hornspäne, Kompost): langsame Freisetzung, bodenverbessernd. Mineralisch: schnelle Wirkung, exakte Dosierung. Bio-Rasendünger kombiniert beides. Kompost aus der eigenen Kompostierung ist kostenlos und hervorragend.

⚡ CalcWolf Insight

The single most impactful lawn fertilizer application is the late fall "winterizer" — applied after the last mowing when the grass has stopped growing but before the ground freezes. This feeding builds root reserves that fuel a strong spring green-up without early spring fertilizer.
