Sowing peas is always a silly game here - the mice come and dig them up overnight and I have to resow. Sometimes it's a wonder I manage to grow any at all!
But this spring I remembered that mice are supposed to hate the smell of mint, and since I hadn't cut back the dead stems of last year's mint yet I did so, and scattered the cut-up stems and dried leaves over the soil after I'd sown my peas.
The peas are all up now, with not a single gap in the rows. Hurrah!
There's a tip I'll remember in future!
