Growing garlic in the greenhouse?

I planted a number of SOLENT WIGHT garlic cloves in large pots a few weeks ago which are currently outside. All have started to sprout. Is there any advantage to put the pots in my greenhouse which is currently empty?

 

I would say probably not, unless you live in an exceptionally cold part of the UK.
You might get the finished garlic head a few weeks earlier.
Mine went into the ground late October and have now all sprouted and are a couple of inches tall. This was also the case when I lived in Essex.

 

Don't know but why not give it a go with some of them.

 

I'd add it depends how cold the greenhouse gets. Garlic needs plenty of cold weather in order to stimulate bulb production, so if it doesn't get the chill hours in the greenhouse it wouldn't really help.
Last year we had such wet conditions that allium really suffered and it's the wet rather than cold that I'd be worried about.

You could speed production up in the spring by moving them into the greenhouse as Nigel mentions.

 

If Solent Wight has been bred to grow on IoW then it will probaply not need much in the way of chilling to produce bulbs.
My alliums ornamental and culinary all suffered last winter/spring with the onionsand garlic slug damage was horrific.
I lost one of my favourite minature alliums in a well drained bed completely and I also may have lost a rather lovely crocus clump near it.
Recently Blackcurrants have been affected by milder winters and efforts have been made to breed varieities that need less chilling in winter, hours below 7°C have been reduced from about 2000 to about 1400.

 

I grow about 20 in my greenhouse borders. They are about 2 weeks earlier than the same variety outside and are larger, also suffering no rust which can affect outside ones

Softnecks need less vernalization than hardnecks, there's still plenty of time for hardnecks in the uk though
