Cool. I really want to learn how to grow onions properly. We use onions almost every day of the year so it is one of those crops you need to grow if you are going to be self sufficient.
It is also important that you grow a heirloom variety that will produce seed that are true to type each year. Onion seed do not store well so you cannot just buy a few kilos of seed and store them away for when you need them.
I have chosen two varieties to start with that will ‘Over winter’. The plan is to sow the seeds in mid to late August for harvest in the spring next year. I am going to also save some of the seed for sowing in the spring for harvest later in the year.
The first variety is ‘Sturon’ White Onion. This is not normally an over wintering onion but if we have a mild winter down here in Cornwall they might do really well and if so we should get some huge bulbs. According to the real seed company they are quite cold hardy and worth a punt at over wintering. I will also start some of these off in January with a bit of heat to aid germination and I may sow some direct into the beds in March.
The second variety is ‘Paris Early’ Overwintering White Onion. These are an over wintering variety so I am hoping we get a good crop from them. These onions do not store too well so I will not be sowing a lot of these to start off with unless I decide to sell them on as sets in the early spring.
The real seen company suggests you sow on or around the 18th of August and as the 18th is on a Sunday this year, that is what I am going to do.
