That is a genius idea. Next year I will do peas. They are so pretty and so delicious but need to be done by July here.
I also start them indoors by soaking the seeds in water.
When they start to show the roots, then I put them in the ground.
That way the soil temperature does not slow germination.
Peas do great in the cool weather once they are started but sometimes getting them started is slow.
Before I put the tomato cages in and the chicken wire on, this year I took a couple old under the bed boxes and put them over the peas.
Nice portable, lightweight cold frames.
When the first peas started poking through, then the tomato cage and chicken wire went up.
