Having heard experts on the tele, as well as neighbours and passers by,
complaining that it's been a bad year for sweet peas, I have to say that
my experience has been the opposite. From half a dozen plants I have
been picking the flowers daily and the house is full of them.

I know that Monty is conducting his own tests but my conclusion is that
the earlier they are sown, the better. Mine were germinated indoors at
the beginning of November and put outside in plastic bags a couple of
weeks later.
