When to Sow Cosberg Lettuce Seeds

Plant Out

Harvest

10-12 weeks from sowing

Where to Sow

Sowings can be made under glass, sow seeds into pots or trays of seed sowing compost at a temperature of 15-20C and lightly cover seeds with sprinkling of vermiculite or compost.
Alternatively sow seeds from April thinly along rows 1.5cm (1/2in) deep and 30cm (12in) apart direct in the vegetable plot. 

What to do next  

Sowings made under glass can be pricked out into individual pots or module trays and grown on until ready to harden off and plant out  into the vegetable plot 30cm (12in) apart between the plants and the rows. Seedlings sown direct outside can be thinned once large enough to handle to 30cm (12in) apart. Thinning’s can also be transplanted into other rows, watered in well during hot dry spells.

Handy Tip

If sowing seeds during hot weather, place the seed packet in the fridge overnight and sow the next day. This cooling down of the seeds will help improve germination.
