Petunia Seedlings

Please can you tell me if I can prick these Petunia seedlings out yet or are they still too small?



Many Thanks

    I'd say you can start Laura. Still a few small ones but I'd make a start the others will catch up.

  • Great, thanks Dave. So I'll try and prick the larger ones without disturbing the tiddlers. What size pots should they go to next?

    Laura you will have a lot of Petunia image I would remove some of the small ones and let the others grow on a bit and then prick them out.  

  • They say that you can prick out seedlings once two leaves have formed but I prefer to wait until they are slightly bigger - maybe 4 leaves but as KEF says take some of the smallest ones out - unless you specifically want all those to grow on Laura.Perhaps sow less next time - something that I have learned from past experience with lettuce seeds - some seeds are so small it is difficult to regulate how many you sow or what the germination rate is going to be.

  • Yes it's a rookie error with the seed sowing...image  I went a bit wild. Not really engaging the brain to realise that every seed could become a fully fledged petunia and that I really don't need that many!!! image

    Laura I often sow too may, but some are so tiny you can't help feels a bit cruel throwing some out but be brave image

    Did your hand slip Laura? image

    The tip of mixing tiny seeds with sand to make it easier to sow more sparingly is a good one. I had the same problem sowing the Harebells I got recently - teeny tiny seeds.

    I'd agree with KEF - thin them out a little and let the rest get a little bigger (won't take them long)- it'll make your job so much easier image

    It's a place where beautiful isn't enough of a word....

    I live in west central Scotland - not where that photo is...

    If it's a packet of mixed colours, bear in mind that some colours may germinate before others .

    In London. Keen but lazy.

    At that size Laura I'd use cell trays, cheap as chips from wilko.

    how long will it take to get these petunia seedlings to a plant big enough to plant out? i have the same size seedlings & they have taken about 6/7 weeks to get to that size, they are indoors, they were on a heat mat but ive turned it off now, and are near light and in front of the radiators although these are only on for an hour or two in the morning.
