This is an improved Japanese variety that is ideal for planting early, and can provide a crop ready to harvest in May to June. The onions are a nice globe shape and have a mild flavour. The young ones can also be used as spring onions in salads.
Garden care: Plant onion sets so that the tips are just showing and firm the soil around them from mid-March to mid-April, 15cm (6in) apart in rows 30cm (12in) apart. Lift the onions when they are mature and allow them to dry before using.

Hello, I am looking to order some Onion Rossa Savonese seed for some work at the University. I need seed that has not been treated with any fungicide or anything. I was hoping you could tell me whether the seed you supply is treated or untreated? Many thanksAsked on 10/8/2009 by Taylor, Andrew
A:Hello There, The seeds we sell are not organic I'm afraid so it is quite possible they have been treated. I'm sorry not to be more help. Helen Plant DoctorAnswered on 10/12/2009 by Crocus Helpdesk
Q:Do Onions need Ash?
Hello, I am preparing a new onion patch for next year, and I am told I need plenty of ash, is this correct and do you stock it? Thank youAsked on 9/6/2009 by Anonymous
A:Hello There, I have never heard of using ash, but onions do need a fertile, freely draining, non-acidic soil. Ideally you should dig
the soil over and incorporate lots of composted organic matter a few months before planting. If the soil pH is below 6.5, you should add some
lime. I hope this helps. Helen Plant DoctorAnswered on 9/7/2009 by Crocus Helpdesk
Q:When do I plant potatoes and other veg?
When is the best time to plants potatoes? Also can you advise me what veg I could grow now until March with poly tunnels?Asked on 10/4/2006 by Bets Ingram
A:You can start chitting your early and maincrop seed potatoes in February, but the best time to plant is in early to mid spring. As for growing vegetables in your polytunnels, you have lots of options. Spinach, kale, and some varieties of lettuce will live through the winter in a polytunnel. Certain kinds of onion work well from an autumn sowing, and you'll get a much earlier crop than if you'd waited until spring. Other possibilities are cabbage, Pak Choy, Chinese cabbage, and most root crops. Leeks, beets, carrots, turnips, parsnips and radishes, can be sown for winter harvestAnswered on 10/5/2006 by Crocus
Q:Am I too late to grow vegetables?
I'd love to grow my own potatoes, onions and carrots, which I use a lot in the kitchen, but don't know where to start or if I'm too late. Please can you advise me?Asked on 1/24/2006 by Debora Everard
A:Now is the perfect time to start thinking about growing potatoes, as they need to be chitted before planting. Chitting just encourages shoots to grow before you pop them in the soil in early spring. The onion sets can be planted in March or April, while carrot seeds can be sown from late February as long as they are protected.Answered on 1/25/2006 by Crocus
There was a time when alliums were thought of only as vegetables. However, the taller varieties with their huge globe flower heads are now one of the stars of the architectural plant world. The stiff lollipop heads off-setting sharp vertical leaves, tall,Read full article
If you just want to grow a few vegetables or have suffered losses with early sowings, buying plants is a great way to play catch-up. Buying plants also allows you to grow vegetables if you do not have the facilities to raise them from seed yourself or wheRead full article
