Peppermint is very versatile, and ideal for making for tangy mint sauce or garnish on new potatoes or peas. Mint has a piquant aroma and as such is disliked by much of the insect world. Above all, plant mint close to all brassicas and it will repel the Cabbage White Butterfly and a sprig or two in your wardrobe will keep moths out of your clothes. It also has a remarkable reputation with indigestion, for calming the nerves, for soothing sleep and recurring sickness.
Sow seeds from late winter to early summer in John Innes Seed Compost. Do not cover the seeds with compost. Make sure that the compost is moist but not wet and seal in a polythene bag until after germination which usually takes 7-16 days at 21-24C. Transplant when large enough to handle into 8cm pots. Later plant out 3cm apart into ordinary soil in part shade.
