Sow outdoors from March to August. Simply fill a large patio pot (minimum 25cm) with compost, leaving a gap 1.5cm from the top of the pot. Place the mat on the compost and firm down gently. Cover the mat with a thin layer of compost then water thoroughly and allow the excess water to drain away. Water well and place in a bright, sheltered position, away from drying winds and out of intense, direct sunlight. Seedlings should start to appear after approximately 7-14 days. Keep the compost just moist and be careful not to overwater, the compost should almost dry out before it is watered again.
