For a prolonged growing and harvesting period start the parsley plants off indoors by sowing into peat pots in the second half of winter. First soak the parsley seeds for a day in water, sow at a depth of 6mm, then germinate in the dark at about 20 degrees centigrade. It should take about 3 to 6 weeks for Parsley to germinate. The plants should then be grown in an area where it will receive plenty of light at a temperature of 20 degrees. The plants can be transferred outdoors about 20cm apart at the start of spring before the last frost has occurred.
