Lettuce - Antartica
Extend your lettuce harvesting season with this outstanding iceberg type variety. Resistance to tipburn, bolting and downy mildew means that Antartica stands well in good condition. The dense hearts, with plenty of crunchy flavour, are ideal for summer salads.
Sow thinly at regular intervals, 12mm deep in drills 38cm apart. Thin seedlings to 30cm apart when large enough to handle. Water lettuce frequently and hoe between plants regularly to prevent weeds from establishing. Dry weather may cause heads of lettuce plants to bolt so watering is particularly critical during the 2 weeks before harvesting. A thick mulch applied around the plants will help to retain moisture in the soil. Harvest lettuce when required by pulling up the entire plant before trimming off the stem with a knife.
