Pricking out Tomato Seedlings


Seedling season is ramping up and the first of my little plantlings to be pricked out and potted up are the tomatoes I sowed back in January. All three varieties, Moneymaker, Yellow Stuffer and Gardener's Delight are over an inch tall and quickly using up all the space in their trays. So it's quite urgent that they're potted up into individual modules before their roots become hopelessly entangled and they start to suffer from being in such close quarters.

Most of my tomatoes are destined for my Farmers Market stall though I plan on keeping about ten of them here at home for both inside the conservatory and outside in the garden. Growing them outdoors hasn't been that successful for me since I grow them so far north and have to contend with cooler temperatures and the ever persistent Blight that seems to affect them just before their fruits turn red.


I hope the rest of my multitudes find good homes through my stall but I've got to give them the best chance of growth in these early days in order to make them 'fruitful'. Good potting compost is essential as is warm conditions and making sure each plant has enough, but not too much space to spread its roots. This means that the tomato seedlings are potted up into small modules now and then in a month's time or so are potted up again into the next largest pots which will be sizable enough to sell them on at the market. It's important to not to pot up into larger pots initially because that means the roots spread out too much and don't bulk up into proper root-balls before they hit the sides of their pot. Not having a strong root system can affect the chances that plant has of growing on once it's been planted out.


Planting these tiny seedlings into their first modules is the toughest part of growing tomatoes from seed. Their roots and stems are fragile at this state and can be easily damaged. So when you're lifting them from the seed tray try to just hang on to them by a single leaf and tease their roots out gently with a pencil or small stick. Once you have them free, tuck them into the new pot or module - first pressing a hole in the centre of the compost makes this step much easier. Gently water in and let them grow until they've put on a couple more inches before potting them on again.


It's another gorgeous day today and I'm off to do some errands before coming home and finishing up potting of the rest of the tomatoes I didn't get to yesterday. I also managed to sow some Toothache plant seeds yesterday and am very interested to taste one of their flowers. It apparently gives you a little electric shock. Probably not to everyone's taste but fascinating nonetheless!

Have a great day and enjoy the sunshine :)

  1. Your seedlings look great and I think you will be most amused with your initial taste of the spilanthes...an amazing little plant whose medicinal value is really quite amazing.

    1. I'm definitely intrigued! Interesting that you say that they have medicinal purposes too Mr. H. I'm going to have to look into that...

  2. Those are nice looking plants and should sell easily. Sometimes tomatoes will rot just before they get ripe because they don't self pollinate so when I don't have too many blossoms, I go along and flick the flowers with my finger which helps self pollination. You might try that on half of them and see if it helps, I never tested it as usually I get too many tomatoes all at once.

    1. The problem here isn't really pollination Sunnybrook but Blight, a fungus that is spread in the air and which affects Potatoes and Tomatoes. Have you heard of the great famine in Ireland in the 19th century? It was caused by a massive case of Blight killing off the potato crops...

    2. I am glad we don't have that yet. Our climate is so hot and humid when the fruit sets that often it will start rotting where the seeds should have formed. So I just plant more than I need and end up with too much when all things work.

    3. You're really lucky you don't have it Sunnybrook and it's because your temperature is so warm. Blight thrives in damp but moderate conditions and is a real pain here!

    1. Thanks Pat - It would be great to make a bit of extra cash off my seedlings this year. Usually I end up giving most of them away ;)

  4. I love pricking out and potting on. It's one of my favourite tasks. Haven't managed to sow any seeds except in the ground but am looking forward to getting some sown soon.

    1. It can be quite therapeutic can't it? At least until you encounter the umpteenth tray!

      Good luck with your seed sowing Lorna :)

  5. Crikey that's going to take you some time to get them all potted up - hope they do well for you.

    1. It took me about an hour to do the Moneymakers and will take about the same time to do the rest. It's not so bad as long as the sun is out :)

  6. Wow...you really take care of your tomatoes!!

    My Mum always starts these off for us and they always do really well so I'm happy to let her continue.

    We haven't sown our seed yet though...should get around to it this weekend.

    The toothache plant sounds ominous...I first though it was to help with pain...but I guess it's really to give you some. I will be interested to see what it looks like and find out what you think about it once it's grown.

    1. You have a very generous mum :) I don't think my mother or even my grandmother have ever grown tomatoes from seed before. It's so much easier to just buy them as seedlings. I'm just a crazy seed lady!

      I heard about the toothache plant last year at James Wong's presentation at the Edible Garden Show. He didn't have any for us to try but played a video of some people eating it - very amusing.

  7. The Toothache Plant sounds fascinating, though I don't think I'd fancy an electric shock on my tongue. I'm sure your tomato plants will sell well on your stall, especially after all the tlc you've given them.

    1. Hi Jo...you should watch this video of people trying them for the first time.

  8. Oh Tanya, I am so envious of all your seedlings. With no kitchen at the moment, I can't seem to get anything organized, like planting early seeds. I like your method though and will have to give this a try. Next year. :)

  9. WoW! Your tommies are well on their way, mine aren't even sown yet, well I lie, my Roma were sown last week.
    Nice little teasre about the Toothache Plant - interesting! Look forward to seeing how it grows :)
    Oh! And I keep forgetting to say Thank You for the 'seed surprise' :)

    1. You're so welcome Mo - I hope they grow for you :)

      It's amazing how quickly the tomato seedlings have grown since I put them into modules last week. Fingers crossed for a long hot summer and plenty of tomatoes on the vine!

  10. That was a lot of seedlings! It's a nice method, I'm new to vegetable gardening and I am inspired by your post. I will try this one and hopefully i'll have healthy seedlings just like yours. Thanks for sharing.
