I have been putting spring onion ends ( left over from the restaurant where I work) in the garden all year, they do a,as ingle well, all grow quite quickly. The Welsh onions don't seem to be as sturdy but I have had success with planting them in the dry winter months

I want to plant them in the same bed as peas what should i do?

Go for it - mine are in the same bed and are going strong so far. Just don't plant the rows too close together or the peas will try to climb up the onion plants and smoother them.

when u cut off the spring onion to level ground how often can u grow your spring onion over again in the same soil thanks

We have brought two sets of different brands of spring onion seeds and neither have done anything not even germinated. The packets said they can be planted now. We have been watering and fertilising but the garden beds are new and dont have a lot of nutrients. But I would expect they would sprout and then not thrive not have nothing comeup. Any tips or ideas as to why this may be. Many thanks
