I love growing Cos Lettuce out on the balcony. Firstly, if you just pinch the leaves off from the bottom it keeps on producing leaves for quite a few months! Secondly, it's super easy to grow. Thirdly, the caterpillars don't seem to be into it...and...
...fourthly, Caesar Salad! Enough said.
Happy gardening, Miss Piggy xoxo
