Which seeds?
---------------
Now retired, having been a gardener for many years, I should know when and
how to sow seeds in the right soil and conditions. You may consider,
depending on which seeds, a germination of 50% is a spectacular success,
I don't. The seeds were supplied by a reputable company that should make
sure its suppliers are not delivering duff seeds. After discussing the
matter with colleagues, I was not surprised to learn that they too have
had
trouble with non germinating seeds, more so in recent years. In the open
garden this could be put down to climatic conditions at the time of
sowing,
but not in heated greenhouses.The non germinating seeds include, lettuce,
spring onion, 'Stargazer'dahlia, coleus, runner beans, chilli and tomato.
For the second year running I have had the most success with radishes,
even our resident four wood pigeons won't touch them.

Well I thought you might be trying to germinate something a little less
common such as Musa or Palms etc.
50% does seem low for the stuff you have mentioned although I would guess
that Seed suppliers might accept that as a pass rate when doing Quality
Control.
Unless you are growing commercially just how many Coleus do you need from a
packet of seeds?
