FAQ
How deep should mulch be?
5–7 cm is the sweet spot for weed control; deeper than 10 cm can suffocate roots and trap moisture against stems.
How much does one bag of mulch cover?
A 50-liter bag covers about one square meter at 5 cm deep — multiply your area for a quick sanity check.
Bulk or bagged mulch — which is cheaper?
Bulk is far cheaper per liter for beds over roughly 10 m²; bags win for small touch-ups because there's no delivery fee.
