Onions are a member of the allium family that includes leeks, shallots and garlic. The largest onion on record is in excess of 16lb so growing a 4lb – 6lb specimen is easily achievable for most enthusiasts.
The onion pictured are some of my current plants that I’m hoping to show in our annual local show and this seed was from a variety called Ailsae, which currently holds the world record. Kelsae is another variant worth growing too.
I will make the main points of what to do here and will make a video of how it all comes together
- Purchase seeds, seed sowing compost and a water retaining aid (Perlite or similar)
- Sow around Mid December keeping them at a constant 18c until germination
- Once germinatedand at the crook stage store at around 14C until early to mid February
- Harden them off gradually. Put into cold frame or greenhouse to allow them to grow on
- Transplant to soil that has had well rotted manure and compost added the previous Autumn
- Keep them weed free and well watered if required and feed with Blood, fish and bone monthly
- Harvest them around 3/4 weeks prior to show to allow drying out period.
