Overview

Tomato plants will thrive on a sunny window sill or in a greenhouse, and may even be transplanted outside in the warmest months. You will need just two small pots to sow your tomato seeds; use a good quality seed compost and keep them in a bright place to ensure they germinate.

How to do it

  1. Filling pot with compostFill two small pots with seed compost. Water the compost with tap water and leave it to drain. Don't use rainwater from a butt as it may contain bacteria, which can cause damping-off disease.

  2. Placing tomato seeds on compostPlace approximately five seeds on the surface of the damp compost, spacing them evenly in the pot. Take your time, as this can be a fiddly job. Then sprinkle a thin, even layer of fine compost over the seeds, ensuring they're not disturbed.

  3. Covering pot with clingfilmCover each pot with clingfilm - creating a mini-propagator, which keeps the compost damp and aids germination.

  4. Labelling potsLabel the pots and place them on a window sill in plenty of light. Aim to keep the room at 21°-25°C while the seeds germinate.

  5. Removng the rootball from the potRemove the rootball from the pot and gently separate each plant with a pencil.

  6. Making planting holes with a pencilIn a new pot containing multi-purpose compost, make planting holes with your pencil. Then, holding each seedling by its leaves, gently tease the roots into the planting hole. Firm the soil around each plant and water.

This is the first time I've grown tomatoes from seed and I wasn't sure when I should transfer to pots. I was going to do this weekend and I now realise this would be too early. Thanks Joe!

Didn't know about watering the compost before you sow the seeds. I grow my toms in a greenhouse, and usually put the 8week seedlings large tomato pots immediatly. Seems to work, but you'd need a greenhouse to do it.

I've already sown my "Gartenpearl" tomato seeds and I now have about a 1" seedlings. Gartenpearl tomato plants can also be grown in hanging baskets. Last year most of my tomato plants were effected by "blight", so this year I'm growing baskets tomatoes along with "Basil" to the white fly leave them alone....... I live in hope that this year I WILL get some decent tomatoes..... HAPPY GARDENING!!!! Scarlet1958
