Appia lettuce: Sowing, planting and harvest calendar
How do you sow 'Appia' lettuce under cover?
When sowing 'Appia' lettuce under cover, allow roughly a month before planting out, adjusted to light and temperature. Aim for germination between 10 and 18 °C. Check your packet's timetable: cover allows early sowings, but a very hot greenhouse does not necessarily improve emergence.
Fill clean pots or a module tray with drainage holes using fine, free-draining seed compost, preferably peat-free. Moisten the compost, sow thinly and cover with a thin layer. Firm lightly and water gently so the seeds stay in place. Label the sowing with 'Appia' and the date.
Keep containers in good light and ventilate the growing space. Check moisture daily without leaving water in a saucer. After emergence, provide enough light to produce short, sturdy plants. If seedlings are crowded, move them gently into individual containers once they are large enough to handle.
Around four true leaves and a rootball that holds together are useful signs for preparing to plant out. The first leaves alone are not enough for moving plants outside. Gradually acclimatise them to wind, sunshine and outdoor temperatures, and check the weather before planting.

Thin seedlings
If your lettuces are crowded and you want whole heads, thin gradually to about 15–30 cm according to the variety. Keep closer spacing for promptly harvested baby leaves. In a module, select the seedling you want to keep.
