Lettuce is a temperate annual or biennial that is grown as a leaf vegetable. There are four main types of lettuce: ‘Butterheads’, ‘Cos’, ‘Crispheads’ (also known as Icebergs) and ‘Loose Leaf’ lettuces. Lettuce is grown commercially worldwide and is commonly used in salads, sandwiches, hamburgers and in many dishes such as Chinese cuisines.

  • Plant & Growing Tips:

    Lettuce prefers cool climates, where ideal daytime temperatures remain below 20°C.

    The lettuce does best in light, sandy, humus rich soils.

    Lettuce are best grown in part shade during the mid summer months.

    Hot, sunny, or dry conditions may cause the plants to turn bitter

    Close planting will produce a dense leaf canopy that will suppress the growth of weeds.

    Keep lettuces well watered as they prefer the soil to be moist at all times.

    Mulch plants to retain moisture.

    If your aim is to achieve an early crop, you should sow seeds under cover over winter to early spring and then transplant. Hardier varieties such as Cos can be planted in autumn.

    To prevent seedlings from wilting, keep moist, shade them from sun, try to disturb roots as little as possible during planting.

    Set plants 20 – 40cm apart depending upon variety.

Please note that the above information and recommendations are provided in good faith and are given without liability for loss or damage suffered as a result of their application. Optimum response to fertilisers will only be achieved when weeds, insect pests and diseases are controlled and adequate soil water is available.

Fertiliser use recommendations are presented as a practical guide to good agronomic practice under most situations. Local soil, climatic and other conditions should also be taken into account as these could affect plant response to fertiliser rates and applications.

For further information we recommend you seek advice from your local agronomist.
