Frequently asked
How big is an allotment?
The traditional full plot is ten rods, 302 square yards or about 250 m². Many councils now split these into halves and quarters because full plots go unworked.
How much lawn seed do I need?
About 35 g per square metre for a new lawn and 25 g for overseeding. A 200 m² lawn takes roughly 7 kg from scratch.
