My wife bought some bulbs while on holiday in the UK, now on her return to Vietnam she has been told that she must Vernalise them or they won't flower.
A quick ask around the bar came up with nothing positive on method, other than bunging them in the fridge for a week or two.
Is there a time of year when this should be done and for how long, at what temp is the freezer too cold.
It was also suggested that she might get more than one flowering cycle per year??????
