LETTUCE
Lactuca sativa
Lettuce requires a rich,
well-drained soil with
constant moisture, it
dislikes acidity.
Sow all year,
avoiding very hot or cold
periods. Select varieties
for the time of year. Avoid
growing solid hearting
varieties during hot
weather, as they are prone
to bolt or to bacterial
diseases. Seed
will not germinate over 30ºC.
The best germination is at a
soil temperature of 20ºC.
In the warmer months
chilling the lettuce seed in
the fridge for a few days
before sowing will improve
germination. Direct sow or sow into
seedling trays for later
transplanting. Cover seed
lightly to 5-8 mm deep, firm
down and keep moist. Space
plants 20-30 cm apart.
Prepare soil with compost or
well-rotted manure
and added
potash, feed regularly with
liquid manure, mulch well.
Avoid watering in the heat
of the day. Growing under
shadecloth is beneficial in
hot areas.
Select a suitable variety to
sow in any season.
