Can You Grow Tomatoes from Supermarket Tomatoes?
Yes, you can grow tomatoes from supermarket tomatoes — but success is not guaranteed, and there are some important limitations to understand before you try. While it can be a fun experiment, supermarket tomatoes are not bred with seed saving in mind, and results are often unpredictable.

This guide explains whether it works, how to try it, and why growing from proper seed is usually a better option.
Why Supermarket Tomato Seeds Are Unreliable
Most supermarket tomatoes are grown for appearance, shelf life, and transport — not for seed quality.
Common issues include:
- Seeds taken from hybrid (F1) varieties
- Unpredictable plant growth and fruit quality
- Lower yields than expected
- Increased risk of disease
- Poor flavour compared to the original fruit
Even if the tomato looks perfect, the seeds inside may not grow true to type.
Are Supermarket Tomatoes Hybrid or Open-Pollinated?
Almost all supermarket tomatoes are hybrids.
This means:
- The fruit you buy is produced from carefully selected parent plants
- Seeds saved from the fruit will not reliably reproduce the same tomato
- Plants grown from these seeds may vary wildly in size, taste, and productivity
Open-pollinated tomatoes (which breed true from seed) are rarely used in commercial supermarkets.
Will Seeds from Supermarket Tomatoes Germinate?
Yes — often they will germinate.
Fresh tomato seeds are usually viable, and many gardeners successfully sprout them. However:
- Germination does not guarantee good plants
- Growth habits and fruiting are unpredictable
- Plants may be weak, poor yielding, or late to crop
So while germination is possible, performance is uncertain.
How to Grow Tomatoes from Supermarket Tomatoes (If You Want to Try)
If you want to experiment, here’s the best way to do it.
- Choose a fully ripe tomato
- Scoop out the seeds with the surrounding gel
- Rinse seeds thoroughly to remove gel (which inhibits germination)
- Spread seeds on kitchen paper and allow them to dry
- Sow seeds shallowly (3–5 mm deep) in seed compost
- Keep warm at 18–22°C and evenly moist
Expect mixed results — some plants may perform well, others poorly.
Problems You May Encounter
Growing tomatoes from supermarket fruit can lead to:
- Plants that grow tall but produce little fruit
- Tomatoes that are bland or watery
- Irregular fruit size and shape
- Delayed ripening
- Increased susceptibility to disease
These issues are common because the seed genetics are unstable.
Can You Grow Tomatoes from Organic Supermarket Tomatoes?
Organic tomatoes slightly improve your chances.
Why:
- Some organic growers use open-pollinated varieties
- Less likelihood of seed treatment or irradiation
However, organic does not guarantee the tomato is non-hybrid, so unpredictability still applies.
Is It Worth Growing Tomatoes from Supermarket Tomatoes?
Pros:
- Fun experiment
- Free seeds
- Educational for beginners or children
Cons:
- Unreliable results
- Unknown variety
- Often lower yields and flavour
- More risk than starting with quality seed
For reliable crops, supermarket tomatoes are not ideal seed sources.
Better Alternatives to Supermarket Tomato Seeds
For consistent results, it’s far better to:
- Buy named tomato seed varieties
- Choose varieties suited to UK conditions
- Select early, blight-resistant, or greenhouse-specific types
- Save seeds from open-pollinated tomatoes you grow yourself
This ensures predictable growth, flavour, and harvest timing.
Can Tomatoes Grown from Supermarket Seeds Be Eaten?
Yes — if they grow and fruit successfully, they are safe to eat.
However:
- Flavour and texture may disappoint
- Crops may be small or inconsistent
Safety isn’t the issue — quality and reliability are.
Key Takeaways
- Yes, supermarket tomato seeds can grow
- Most supermarket tomatoes are hybrids
- Plants rarely grow true to type
- Germination is possible, but results vary
- Best used as an experiment, not a main crop
Final Thoughts
You can grow tomatoes from supermarket tomatoes, but it’s a gamble. While seeds often germinate, the plants you grow are unlikely to match the fruit you started with. For gardeners who enjoy experimenting, it can be fun and educational. But for dependable harvests, good flavour, and reliable yields, growing tomatoes from proper seed varieties is always the better choice.
