    Default Tomato germination

    My toms planted about 3 weeks ago have not germinated. I simply planted three to a 4inch pot at a depth of about 1/2 inch and have kept indoors

    The seed is last year's - could this be an explanation, or does anyone else have any suggestions to help germination

    thanks VF

    Hi

    Half an inch sounds very deep for toms.

    Vegetarian Fox,

    You didn't metion about the temperature as tomato need at least 18C constant temperature to germinate (they will do better if given higher temperature).
    I always sow my tomato seeds pretty shallow lesser than 0.5cm deep. Have you try to gently dig in the soil ? They might have germinated but hasn't managed to emerge. If it is from last year seeds (last year harvested seeds), they should be still viable as they will keep well for 4 to 5 years if stores in constant cool temperature.
    I grow, I pick, I eat ...

    Sorry to hear that, it is somewhat long time for germination. Last year's seeds should be perfectly alright, tomato seeds keep well even beyond 5 years.

    I had problem with 3" pot even in heated propagator, never mind without it although I did have 1-2 successful germination out of 10 sowings which may have been have due to the tomato variety.

    For me personally, I prefer to use the heated propagator as it can take around 5 days to germinate using fresh compost (do not cheat), shallow tray (mine was 1 inch deep) and only very lightly cover the seed, do not bury and keep the compost moist. I'm sure you can replicate the temperature without a heated propagator but the toms need warmth.

    I planted my seeds at 1cm depth one and a half inch seems a bit deep. What variety are they, I've always been lead to believe that F1 varieties dont keep well after a year.
    Do not meddle in the affairs of dragons for you are crunchy and good with ketchup!

    Half an inch depth shouldn't cause a problem.

    I think they'll still germinate but you need to warm them up a bit. It is surprisingly difficult to kill an undamaged tomato seed. You might get a few duff ones, but it's very rare for them not to appear eventually. This is why impatient people who recycle their compost for another crop find tomato seedlings coming up too

    When I'm not in a rush (and I'm usually not!) I just sow tomatoes in modules and put them anywhere indoors - they can take a while to come through (a couple of weeks or so) but they always pop up in the end. If I want some certainty or the seed is out of date I might try a bit harder and put them in the airing cupoard for a few days.

    As spring moves on, if the weather is good, a sunny windowsill and mild nightime temperatures will make them germinate more quickly, too.

    Really? If it helps, all my quickly germinated tomatoes were non-hybrid variety. Don't do hybrids here, esp toms.

    Shouldn't be any problem with keeping tomato seeds from one year to a next whether they're F1s of not. Basically some varieties of seed keep, some don't and toms are pretty good. Have managed to germinate ones which claim to be 5 years out of date in the past.

    Some of us live in the past, always talking about back then. Some of us live in the future, always planning what we are going to do. And, then there are those, who neither look behind or ahead, but just enjoy the moment of right now.

    Which one are you and is it how you want to be?
