How to SowSow directly into the ground, preferably in full sun, from April to September. Loosen the soil to at least 30 cm deep. Run a straight groove along the bed, about 1 cm deep. Stick a label in the soil at the edge of the bed. Mix the seed with fine sand and sow as thinly as possible along the groove using thumb and forefinger. Cover the seed with 0.5 cm soil, press down lightly and sprinkle with water. Extra rows should be 20 cm apart.
Sow under glass from March – use a cold frame or a box indoors. Use a fine potting compost and sow the seed mixed with fine sand, evenly over the soil. Cover to no more than 0.5 cm. Press down lightly, sprinkle with water and cover with a sheet of glass or cling film. Place the box in the light at room temperature or stand the box in the cold frame. Once the seeds have germinated, remove the cover. Using a miniature greenhouse is also suitable. Seeds germinate in 7-10 days, depending on the temperature. Approximately 2-3 weeks later, the seedlings can be thinned and planted out - in peat pots they can remain indoors or in the cold frame for longer and transplanted outdoors later. Do not allow the soil to dry out. Plant outdoors from May – at around 15 cm intervals, in rich, moisture-retentive soil.

Try to prevent lettuce from bolting - the lettuce produces a stalk which eventually forms flowers which then turn to seed. This happens more often in the summer and may vary per lettuce variety. Bolted lettuce is still edible but tastes bitter. Try to harvest before this happens.
HarvestingIceberg (Crisphead) lettuce can be harvested in 2 ways:
1. Use a knife and just cut the lettuce off at ground level.
2. Use a garden fork and flip the heads up, root and all.
Show moreIceberg lettuce is also known as crisphead lettuce. Today there is a wide selection of lettuce varieties. Some are suitable for an early harvest, others for summer cropping and some are for in the autumn. There are also varieties that can be grown all year round so always try to choose the right type of lettuce to suit your taste. The varieties are split for spring, summer and autumn according to their propensity to 'bolt'. If for instance you were to sow an early variety in the summer, it would be more than likely to bolt immediately. Not what you want! So choose the correct variety per season! With a cold frame, you can extend your harvesting season by almost 2 months. The Iceberg lettuce varieties belong to the species Lactuca sativa. Lactuca belongs to the Daisy family (Asteraceae).
How to useThe Iceberg has a firm leaf and will definitely last a week in the fridge, longer with the roots on. All lettuces are of course great for making salads – mix them up! The fresher the lettuce the tastier and crispier it is. Try making a lettuce soup – handy when you have an extra big harvest as you can then store it in the freezer.
