Size guide - Tray of 20 Plug Plants 

Securely rooted, strong plants in mini-plugs of compost. Will need to be transplanted and grown for a short while before planting out ready to flower. Tender varieties will need protecting from frost. Compost volume around 3cm deep x 2cm square. Foliage height 1.5cm-5cm (depending on variety). Full growing instructions are provided.

Onion Ailsa Craig – A very reliable plant that produces a mild flavoured large onion.

  • Depending on the weather in your area, onions can be planted straight into the ground, into fertile soil in an open sunny site preferably.
  • Planting closely together will result in smaller sized onions so ideally space them every 10cm or so in rows 25-30cms apart.
  • Onions are shallow rooting so weed regularly so they are not competing for food and water and give an occasional feed. 
  • Harvest the onions when the leaves yellow and collapse which will probably be around late summer/autumn.
  • Ease them out of the ground with a garden fork and lay them in the sun to dry out or use them straight away.  Onions can be stored in a net bag and hung in the shed or garage until you need to use them.

these arrived in very good packing condition and I'm not the most savvy (ignore all frost warnings etc etc) of gardeners, I planted them out after a few days and they are now doing very well

Good strong seedlings arrived when scheduled. Of the 20 plugs, one was dead, but overall very happy with the quality of the product. Remaining 19 planted and all seem to be doing well so far.
