IS SPRING ONION ANNUAL OR PREANNUAL (perennial?)
18 Aug 17, Mike (Australia - sub-tropical climate)
Most onions are grown annually. Too much messing around I would imagine to regrow. Otherwise cut the roots off and put in water and they will grow. Google it.

Why can't you plant near peas or beans? If they are growing upwards and spring onions are at the base but a bit off their root system would that help growing close or it just a i don't like growing with you kinda thing..

Hi Ben, Best to plant something else in between peas/beans and onions. Peas/beans have symbiotic bacteria amongst their roots which fix nitrogen into the soil, while the onion family are antibacterial - hence they fight one another's good points. If you put say a row of leafy greens between the two, then the argumentative roots of the two foes will be separated, and the leafy greens will benefit from both the extra nitrogen plus the extra pest protection of the onions. Win win win.

what are the best time to grow spring onion
10 Dec 15, Gay McCosker (Australia - tropical climate)
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.

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
