Everyone is struggling with slugs this year. Last year they murdered all my brassicas. I put some brussel sprouts in last week, they are doing well, but the telltale slime trails and nibbled leaves are appearing.
we have a pampas grass (big mistake, it was supposed to be a mini at only 6 feet, and pink - it's big and beige 😬).I hadn't got round to giving it a haircut, and suddenly thought - the leaves have sharp edges, wonder if the slugs would cross it. So I got the spring tine rake out and raked out all the dead leaves, OH chopped them up with the shears and I've spread them all around the plants, making sure there are no paths for them to get through.
saves burning the leaves, they don't really compost well.
Will let you know if it works.
