A common problem with onions grown from sets is premature bolting, or running to seed, so I shall keep an eye on night temperatures and bring the trays indoors if frost is forecast so they don't get a check in growth. Onions from sets is a popular class in my local shows. Whether I can grow them to a good enough standard to exhibit at NVS shows against onions grown from seed is a different matter but I think it is possible.

Most of my shallots are now showing green top growth although it is looking a little 'unhealthy' at the tips. I find this very often to be the case in the early days as the plants are often out of kilter whilst they find the correct balance between root and leaf growth. A good watering with rain water from the butt soon sees them greening up.

An important task through the winter months if you have greenhouse borders is to make sure you water them regularly even though you don't actually have anything growing in them. This mimics winter rains and ensures any nutrients are not locked away. I'm not into the science of it but it's called a 'build up of salts' and I will often pour several buckets of water over the beds to ensure I have a workable soil come Spring time.
This particular border is where I usually grow my cucumbers but a different method for cu's means I shall be able to try a few 'exhibition' onions here this season.
