I just wanted to share a small success story. When we moved house we inherited two stories of window boxes. A friend gave me a great window box starter pack of little daffodils. I decided to plant them in the boxes outside our bedroom (upstairs). Whilst planting them I sprinkled in a few lettuce seeds. My theory is that snails and slugs might be too lazy to climb up to our bedroom window to eat lettuce. And may be they can’t smell that far. Well, whether by luck or good judgement the window boxes are full of pristine lettuce! I recommend it.
