bad year poor germination
Excessive rain can absolutely affect lettuce growth, especially if it occurs shortly after planting or during germination.
Heavy or prolonged rainfall can:
Wash seeds deeper into the soil, making it difficult for seedlings to reach the surface.
Cause soil crusting once the surface dries, preventing seedlings from emerging.
Reduce oxygen in the soil, slowing germination and root development.
Promote seed rot or damping-off diseases, particularly in cool, saturated soils.
Leach nutrients, which can slow the growth of young lettuce plants.
In Winnipeg this spring, many gardeners experienced challenges due to periods of frequent rainfall and fluctuating temperatures, which created less-than-ideal conditions for lettuce establishment.
If only a small percentage of your lettuce germinated, heavy rain could certainly have been a contributing factor, especially if it occurred within the first week after planting. Other factors such as planting depth (lettuce seed should be covered very lightly—about ⅛ inch or 3 mm), soil temperature, and consistent moisture also play important roles.
