Profondeur

Laitues et herbes : 15-20 cm. Tomates et poivrons : 30 cm. Carottes et pommes de terre : 40-60 cm. Un bac de 1,2×2,4 à 30 cm : 0,86 m³. En vrac : 25-45 €/m³. En sacs : très cher (100-200 €/m³).

Meilleur Mélange

1/3 compost + 1/3 tourbe (ou coco) + 1/3 vermiculite. Ce mélange produit des résultats exceptionnels en potager surélevé.

⚡ CalcWolf Insight

One 4x8 raised bed using the Mel Mix method (1/3 compost, 1/3 peat, 1/3 vermiculite) produces as much food as a 100 sq ft traditional row garden — using 80% less space and 90% less water.
