How many snap pea plants would you sow for 2 adults? I'm just looking for enough to garnish salads and occasionally as a vegetable for dinner. I certainly don't need to be eating them every night, will be eating the whole pod not shucking, and I don't plan on freezing any.
I would plant half a packet one week and the rest 2 weeks later. If you can work your garden, now is a good time to sow.
The soil needs to be warm for germination but not as warm as other crops. Once they are up and growing they are pretty hardy.
You want to be able to harvest when its still cool.
