Question

What are the tiny black spots that you have to wash off organic lettuce?

Answer 1

Insect droppings and bits of soil splashed up during watering.

Answer 2

Tiny bits of soil. Organic lettuce isn't put through the same vigorous washing as non-organic when it's been harvested so a bit of soil gets left on it. That happens with the lettuce we grow. I hate it because it's a bit gritty sometimes but it's harmless.

Answer 3

fly poo

Answer 4

They're probably soil which you'll need to wash off - just like you do if you grow your own!
