I'm really glad you started this
thread. I love cooking and eating yellow split peas. I bet they would taste even better if I grew them myself.
Do you have a photo of the peas for us to see? I've never seen them un-split before.
I know almost nothing about growing them, but I am looking forward to learning from others here.
Fava Beans, however, I know a bit about growing. I've been working with them for a few years now. I usually plant mine in Oct, but sometimes as late as the end of Feb. We have mild winters here, so if you have a proper winter, then the usual instructions are to plant them as soon as the soil can be worked in the spring. Favas need cold weather to set their flowers and stop making beans once the weather warms up.
Ops... pre
coffee brain seems to have fava beans on the mind.
Lentils. Lentils I plant in the early spring, about the same time I plant munching peas (green garden peas). They seem willing to survive a frost so long as they aren't too tall. I haven't tried overwintering them yet, but I imagine we could here where the winter is mild.
Peas in general like colder weather for germinating than something like beans or
tomatoes. If you have enough seed, it might be worth planting 4 or 6 seeds in the soil at different times of year to find out what works best in your conditions. There are a lot of general ideas on when the absolutely most bestest time ever to do something is... however, they aren't necessarily growing in the exact same conditions as you. So it's good to try for yourself if you can, and treat the rest as more guidelines than rules.
I'll have a read through my
books, but hopefully someone from your part of the world can chime in more about growing these peas.
