Lettuce For Constant Crops

Lettuce varieties growing in a raised bed

by Garden News |

Lettuce produce leaves quickly and productively and they're versatile too. Sow thinly in rows for traditional mature heads or thickly in rows or patches in borders or pots for a cut-and-come-again crops.

Rather than harvest individual heads you can progressively strip off lower leaves leaving the heads to grow on.

Mix varieties of the same lettuce, such as red and green 'Lollo' or 'Oak' or 'Cos', and grow together for ornamental effect. Others, such as 'Freckles', have spotted leaves and look good in borders, windowboxes, pots and baskets, and perform in semi-shade as well as full sun.

For a steady supply of leaves use those which don’t produce a tight heart, stick to open varieties. If space is tight use smaller varieties such as butterhead 'Tom Thumb' or cos 'Little Gem'.

If grown close together they can be cut as required when leaves are young and tender, and will grow again – just leave 2cm (¾in) of stem in the ground. Cut-and-come-again varieties can be bought as a mixture.

Sow seed thinly in rows in sun or semi-shade from now until June. Sow at fortnightly intervals for a successional harvest. Alternatively sow seed in pots under glass and prick out into modules, growing on, then after hardening off plant them out into their final positions or pots. Keep plants moist and avoid droughted soil for best results and protect against slugs and aphids.
