  • Hi you should start to see signs of life in a week, sometimes 10 days. It depends on the variety of tomato. I would sow a new batch if you don't see anything after two weeks.

    In a heated propagator or very warm windowsill or cupboard, could be as little as 3 days, although usually it's 5-10 days.

    In cool conditions they can fail to germinate and rot, so I agree with Gardenmaiden about starting again after two weeks.

  • I always make sure the compost is not cold from sitting in the garden.  I very slightly warmed a little up in the pot before sowing the seed this morning.  (in the microwave!)  Mags

    I think that is a great tip about warming compost. My first attempts this year of sowing seeds were using compost from cold bags out in the shed. The lady at the garden center told me to put new bags indoors by the radiator. I have them there now and have been sowing into the pre-warmed soil and placing the trays in the propagator. Most things are showing in 3-5 days and not lost any to rotting yet.image

  • Yes, should've said that we have our compost indoors for a couple of hours to get warm before using. We use a propagator under lights and the earlier comment is generally our result for germination of 95% of the seeds we sow.

    Mine germinate 7-10 days in unheated propagator in dining room image in light but not direct sun in temps of about 18C in day 12C at night but don't do them until mid March, night temps too cold until then.  If very cold overnight I put an old towel over the top to keep them warm and get up early to uncover them image

  • thx everyone
