Advice from the seed producer and author

Yves Gagnon

Growing conditions for lettuce

All lettuces produce well in cool spring and fall conditions. Because they tolerate frost well when young, they can be transplanted early in the season. For a summer harvest, choose ice, romaine, or oak leaf lettuce, which are better suited to heat. Lettuce requires high levels of organic matter and consistent moisture. The soil should be loose and deep. Amend the soil with mature compost at a rate of 500 kg to 1 t/100 m2. The recommended pH for growing lettuce is between 6 and 7.

Lettuce Crop Rotation

Lettuce is grown in the second year of rotation after a crop that has received a generous supply of young compost.


Companion planting of lettuce

Lettuce works well with brassicas. It can be grown in companion planting with winter cabbages, for example, transplanting the lettuce in early May and the cabbage plants in early June. This way, the two crops will overlap for a while. Once the lettuce is harvested, the cabbages will have plenty of room to complete their growth. The same technique can be used with broccoli, cauliflower, and Brussels sprouts. Lettuce can also be grown with all other leafy vegetables. Early in the season, it can be grown between rows of asparagus.
