Last year I planted a packet of peas in the ground. A month later not one had survived. Mice had dug them all up.
I love fresh garden peas, so worked out a way to stop the mice getting to them. I know I can grow peas in pots and then transplant them, but a hundred pots is a pain.
I came up with the idea of using a window box trough. This has an overhanging lip, so mice cannot climb into it. I make sure the trough is away from any mouse climbing aids, too.
It is a simple matter of half filling the window box with compost, scattering the peas over it and then adding another two inches of compost to cover the seeds. Tamp the compost down and water.
In a week your pea seeds will have sprouted. Three weeks from planting you will be able to plant your pea seedlings in the ground.
Use your hand to extract a few seedlings and tease the roots apart. Just make a small hole with a dibber or small trowel, put one seedling in each hole and fill the hole with soil. Make your planting holes about six inches apart and your pea plants will grow up and support each other.
This year I did not lose one pea plant to the mice. I have never read any advice anywhere that suggests that pea plants can be transplanted but it works. I planted my peas in early March. I will plant another packet before the end of May to give me a succession of pea pods into autumn.
