LETTUCE
Lactuca sativa
Lettuce requires a rich,
well-drained soil with
constant moisture, it
dislikes acidity.
Lettuces can be sown all year
in most of Australia,
if very hot or cold
periods are avoided. Select
the correct variety
for the time of year and the
area you live in. Generally
avoid
growing solid hearting
varieties during hot
weather, as they are prone
to bolt or to bacterial
diseases. In tropical areas
only the lettuces marked
H
for 'hot and humid' should
be selected; the sowing time
in these areas is limited to
April through July. Lettuce
seed
will not germinate over 30ºC.
The best germination is at a
soil temperature between 15
- 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 mm deep as
lettuce needs light to
germinate, 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.
