Q What can I use to prevent seedlings damping off? PL SNELL, CHELMSFORD, ESSEX
A Using clean trays and fresh compost is the best way to prevent damping off. Also avoid sowing too thickly and overwatering. You could also try Citrox (£6.99 for 500ml) – an organic, citrus-based disinfectant that kills bacterial and fungal diseases. It’s available online from Agralan.
