Learn to Grow Salad Vegetables

  • Lettuce and other edible leaves
  • Edible flowers
  • Sprouts

While a lot of plants are edible and tasty, others are not palatable because of taste or texture.

A lot of plant leaves contain toxins which can upset the human body, cause illness, long-term damage or death.
Every human who grows or eats leaves (i.e. most humans) should know how to differentiate between palatable, edible, nutritionally beneficial leaves and those that are not those things.
Some plants also produce edible flowers. Sometimes flowers are mixed into leafy salads to add colour and to provide different tastes.

This course teaches you what to grow and how to grow it.

What Do You Know about Lettuce?

Do you realise there are many different types of lettuce, and many different and varied cultivars within each type; and that is just lettuce!

Butterhead cultivars are varies of lettuce with soft leaves that have a buttery texture. Leaves are delicate and loosely folded on top of one another, green on the outside and creamy to light green in the centre. Butterhead rarely tastes bitter. Head weights range between 0.3 and 0.7 kg. Butterhead is easier to grow than the crisp head types and has a greater tolerance to temperature extremes. Butterhead is also less likely to bolt. It matures in approximately 55 to 75 days. Butterhead may be harvested by removing only the outer leaves or the entire head. 

Iceberg Cultivars (var. capitate) (also known as crisp head) has a tight firm head of crisp leaves.  It is a popular but more difficult to grow lettuce variety since it is susceptible to heat, water stress and rotting. 

Loose Leaf Lettuce Cultivars (var. crispa) (also known as leaf lettuce), speciality, fancy or European lettuce, does not form a head or heart. It is considered the easiest type of lettuce to grow and is often grown in hydroponic systems. Loose leaf is heat-tolerant and slow to bolt.

Romaine or Cos Lettuce Cultivars (var. longifolia) is upright in form and grows up to 30 cm tall. The leaves are spoon-shaped and tightly folded with thick ribs. The outer leaves are medium green and sometimes tough, while the inner leaves are greenish white and tender. The flavour is sweeter than the other types of lettuce. It matures within approximately 70 days.

Summer Crisp lettuce is a large, flavoursome lettuce that does not bolt. It has thick, crispy exterior leaves. The heart has a sweet, slightly nutty flavour. Summer Crisp matures within 55 to 60 days.

 
If you want to get the best value from a crop (lettuce or any other); you need to choose the right variety, to suit your needs, in the place you grow, the way you grow it and the tme you are growing it - and for the purpose you have.  That knowledge starts with this course, and the builds with further experience.
