In My Seed Box for 2026 - Onions From Seed

  

I have grown Onions from seeds in the past and was quite successful but for the last few years I have been using sets. I did have problems with white rot on Mill Green Plot 1A and I tried growing on my old plot on Spencer Road and still had white rot problems. 

I think the art is to watch and harvest as soon as one sees the signs of white rot and of course rotate the crops on the plot. I have an additional half plot, I have decided that it's once again time to try growing Onions from seeds. 

In the beds where I have seen some white rot in 2022, I have grown Calient Mustard that's a great organic means of creating a soil environment that's uninviting to the disease. I had a great crop of over 300 onions in 2023 and not so many in 2024, and much less in 2025 due to limited space as I transition from ground level to raised beds.  

Onion seeds only last 2 - 4 years if kept properly, so I have ditched any seeds with a sow by date before 2024, as normally there is only a 2 year allowance by seed companies, and not all seed companies publish the saved end of date on the back of the packets .
