Lovely Lettuce
General Info: Lettuce is a cool loving, fast growing,
leafy annual that does not like high heat or direct summer sun. It tastes best when grown quickly in
moist, fertile, mineral-rich soil.
Seeds: Small, black and white, shaped like arrowheads. Seeds
store for 3 years and germinate in 6 -12 days.
Varieties: Hundreds of varieties that fall generally into
the following categories:
- Loose-leaf - good for multiple harvests of leaves and in mesclun
mixes
- Romaine/cos - heat-tolerant long firm heads
- Summer Crisp/Batavian - looser crispy heads
- Crisphead - tight iceberg type heads - needs long growing
season
- Butterhead - soft loose heads - more tender
Create your own mixtures. Choose hardy winter varieties to sow in the fall.
Indoor Sowing: Sow indoors in planting mix, 2 seeds per
container during late winter and early spring. Harden off and transplant when seedlings are 2” tall at 2”-3” spacing in rows or blocks.
Keep some seedlings handy during the summer to interplant wherever there
is shaded space.
Outdoor
Sowing: Direct seed small amounts in the garden or greenhouse
from spring onwards every 2-3 weeks until late September. Sow seeds
about 1” apart in 8”-12” rows or thinly (1 seed
per square inch) all over a 2-foot square block.
Sow on the surface
and cover
with a light dressing of soil (less than 1/2"). Water gently and
protect with a floating row cover.
In hot summers, put seeds in the fridge for 1 week and
pre-sprout in a damp paper towel in a sealed plastic bag.
Soil: Prefers rich, slightly alkaline fertile soil, high
in humus and nitrogen. It will tolerate poorer soils if mulched and fertilized
well; use alfalfa pellets or
soybean meal for additional nitrogen.
Till the top 3” of soil to a fine texture and add compost and
Bountea.
Bountea: Add
M3 to the Bountea for nitrogen and minerals.
Drench the soil and spray the whole plant every 2 - 3 weeks for a fast
growing crop.
Cultivation: Keep the soil evenly moist;
water
through the row cover until seedlings are strong and to keep them cool. Spray the
leaves with cool water if they wilt but not in the afternoon/evening.
Use shade cloth or lattice over the
plants to reduce heat.
Thin the plants as needed (see harvesting) without disturbing the roots.
Mulch the soil if there is room around the plants. Interplant on the north or east side of
taller shade-giving plants such as beans, tomatoes and broccoli.
Harvesting: Loose-leaf types - crop the leaves when they are 4"-6" high, cutting them off 1.5" off the soil. For all types - crop the larger outer leaves or cut out thinnings for use. Leave 6" space around heading types and allow to grow until fully formed. Stop lettuce bolting by pinching out the center shoot.
Nutritional Value: Lettuce, though high in water is an
excellent source of chlorophyll, vitamin A, vitamin K, folate, vitamin C,
manganese, iron and chromium. It is high in dietary fiber and minerals.
Bountea-grown lettuce has more than twice the mineral and
sugar (brix) levels of organic hydroponic-grown lettuce. Naturally, it tastes amazing.
