Can You Grow Tomatoes from a Slice of Tomato

Can you grow tomatoes from a Slice of Tomato? Here’s how to do it (and what not to do) based on an experiment I made last year.

In a previous post, I talked about how to save tomato seed and store them for the next season. But there’s another way to grow tomatoes based on an experiment I made last year when I was getting started in edible gardening.

Grow Tomatoes from a Slice of Tomato

I cut a slice about 1-1.5cm thick from the middle of a ripe store-bought tomato, put it in a small pot and covered it with about 1.5 cm of potting mix. I kept it moist with a daily mist of water and about two weeks later, the seeds germinated and I had tiny seedlings growing.

Once the first set of true leaves formed, I thinned out the seedlings and kept the strongest ones. When they grew to about 10 cm high, I planted the healthiest looking plants into a large container, added powdered eggshells for a calcium boost and waited. And I mean, waited.

The mistake I made was that I did this experiment in autumn/fall when tomato season was well and truly over in Sydney’s temperate climate. During winter, the seedlings didn’t grow much and the leaves turned dark purple. I thought the plants were dying or low in phosphorus but I continued to care for them during the winter months and once spring came along, the leaves started turning green and the plant showed significant growth.

I transplanted them into larger pots, 30cm in diameter and as the weather warmed up, tiny flowers appeared and fruit started to form. I fed the plant fortnightly alternating between a liquid fertiliser and seaweed tonic.

As you can see from the photo above, I managed to harvest a handful of tomatoes before the plant eventually gave up, either due to the life cycle or the irregular watering during the Sydney drought.

If you’re asking yourself, can I grow tomatoes from a tomato? The answer is yes. Here’s what I would do differently:

  1. Use heirloom tomatoes preferably from a farmers market not a supermarket variety.
  2. Plant it in season, which is spring-summer for Sydney’s climate.
  3. Add organic compost and a little blood and bone when transplanting into the larger pot.
  4. Water more regularly as tomatoes love water and are heavy feeders.

Would I do it again? Not likely. Seed is cheap when you buy it online and I’d much rather grow tomato varieties that I can’t buy every day.

Next season, I’m hoping to grow Indigo Rose Tomato, Reisetomate, Tigerella and Green Zebra – all from seed.
