Hi Charles and other celeriac experts
I sowed my celeriac (Monarch) seed three weeks ago in my mini propagator which gives a temperature of about 20°C but, unlike the rest of the seeds, there is no sign of them. I followed the instructions on the packet and I think it was to sow 1/2″ deep. I have since read different sowing instructions on the blogs and the seed merchants’ websites. Some say do not cover the seeds at all as they must have light to germinate, Thompson & M state 1/8″ at 20-25°C, Suttons state 10-15°C, Mr Fothergill (for my second attempt) say 1/2″ at 15-20°C. I have also read that high temperatures inhibit germination.
They all mention that germination is slow at 14-21 days. I am aware that information, sometimes incorrect information, is copied from blog to blog but I would have assumed that the seed merchants have the correct information. It seems that either several of them are incorrect or Celeriac will germinate under a wide variety of conditions.
I have only my 20°C propagator and an unheated greenhouse. What would you suggest? If I get it wrong this time we will be into April which I gather is on the late side for sowing celeriac, and we shall have a winter devoid of one of my favourite veg.
I live in sunny Exmouth where Spring temperatures are higher and April and May frosts are much less frequent than at Homeacres.
Thank you very much indeed.
John
