    What am I doing wrong? Every time I try and grow tomatoes from seed, it's the same thing. Leggy seedlings, which then try and sprout a couple of leaves, then kaput. My current batch looks like this:

    2016-05-02 20.14.59.jpg

    Half are "Red Alert", half "Maskotka". The one by the label was a late sprouter so it's about a week behind the others.

    I grow them indoors to start with, and this year I have been very cautious about putting them outside - they're out now but the temperature is about the same as indoors, and they're in a very sheltered spot. I thought perhaps a bit more sunlight might help - my windows are SE or NW facing, and they are at the NW end, but last year I tried them in the SE and same result. I'm using multipurpose peat free compost, and they sprouted no problem at all - the trouble starts when I get to the true leaf stage.

    Help!

    Cant say I like the look of the compost,:smile:, that said, I usually sow in a pot of around 4ins or so, then transplant into separate pots once they are starting to form true leaves.

    At that point you can plant lower, burying the stem almost up to the seed leaves, so you lose any leggy-ness that might have occurred.

    I think yours might be "damping off", a fungal disease.
    Possibly you are keeping them too wet without enough fresh air.

      I agree with Pete, nikiruska, your compost looks a bit coarse and not very good. I don't sow mine in seed compost but ordinary General Purpose Compost and I get nearly 100% results. When you say they're outside do you mean without any cover or not in a Green House or Cold Frame? If so, you're probably taking them outside too early.

      I re-read your post and saw you were using Peat Free Multi Purpose Compost, well, despite all the hype about peat free compost I don't think there's a good reliable one out there yet. I'm conservation minded like most gardeners but I wouldn't ever use the present peat free compost for sowing or even growing on the plants...........and I think your Tomato plants are telling you that. :dunno: It's not too late to have another crack at sowing some more Toms with regular peat added compost. You can get seed trays and clear plastic covers for them from Wilko's and I use the clear plastic covers to keep in the moisture while keeping the compost from drying out.
      So my recommendations are, [a] change to peat added compost and forget the peat free type, use clear plastic covers over the tray/cells to keep the moisture in but keep an eye out to stop them drying out, [c] have a little patience by keeping them in the SE window longer next year and, if you can pot them on as soon as the true leaves appear. Good luck if you decide to sow again.:coffee::snorky:

        My compost last year was ordinary multipurpose and I got the same result, although they got a bit bigger before they died. I think you're onto something with the fresh air thing - windows are rarely open in this house because I have a noise phobic dog!

        They have been under cover outside, and only out for a few hours for the past couple of days. They've only not had cover today as the temperature's been the same as where they sprouted. The damage started before I started putting them out.

        I need to get some more compost anyhoo so I'll have another go, and put them at the front. And now I'm thinking about it, I could put them in my spare room - SE facing, the door is shut and the window is always locked open at a tiny crack because I have other animals in there. Enough for ventilation but not to make the windowsill cold.

        Thanks :)

            That compost look dry, it's hard to tell from a photo, but if the surface has dried out then it's time to water them.

            I'd say there is not enough sunlight reaching them, that's why they are thin and leggy.

                  If you're not having much luck with your tomatoes from seed, maybe buy in some seedlings or cadge some off a friend. There are usually plenty going to good homes at this time of year.

                  I don't think putting them out at such a small size is a good idea. Mine are outdoors now but they are 1ft tall and I've been hardening them off for weeks...and most people will say it's still too early. Your seedlings aren't strong enough to withstand cold winds.

                  I agree with the comments about your compost looking dodgy. Give them as much light as possible and perhaps try dusting the surface of the compost with cinnamon powder. The RHS are recommending it as a deterrent for damping off.

                        It isn't dry, I guess that's poor lighting! I water from the bottom too.

                        IceColdRum - it's the B&Q Verve peat free stuff.

                        Cinnamon - I'll keep them indoors then. I've not been putting them out if there's any wind, I know they are only titchy things! But they can stay in, no problem.

                          I agree with above stay away from that muck tried it once never again. I use Canna professional from the hydroponic shops, may be too expensive for some at £12 for 50 litres but I use it for everything seed sowing, potting up and final pots. I have never looked back since using this.
                          Pic of my toms ready to go in greenhouse this weekend. Not suggesting you can replicate this on a windowsill as I have a heated conservatory. However I used a windowsill for years.
