Can You Grow an Olive Tree From a Pit? Yes, but Slowly
It is a tempting idea: save the pit from a good olive, plant it, grow your own tree. You can — olives do grow from seed. But what sprouts will not be the variety you started with, will sulk for years before fruiting, and explains exactly why growers almost never propagate this way.
The pit-to-tree dream is a good one, and it is worth doing for fun — but go in with your eyes open. Two facts sink it as a way to get the olives you actually want: an olive seed is reluctant to germinate, and even when it does, it does not grow into the tree it came from. Understanding why is a neat lesson in how the whole olive trade propagates its stock, and why a nursery cutting beats a saved stone every time you want real fruit.
It works, slowly, and not as you expect
An olive pit can germinate, though it is stubborn: the hard stone often needs cracking or a long soak before the seed inside will sprout, and even then germination is patchy and slow — some cultivars can take more than a year, occasionally several, to come up at all. The bigger surprise is what grows. Olives do not come true from seed, so a pit from a prized Kalamata or Picual will not give you that variety. Seed-grown trees tend to revert toward the small-fruited wild olive, giving a brand-new, genetically unique plant that is often wilder and less useful — the way an apple pip never yields the apple you ate. And a seedling olive can take a long time to fruit.
Why growers graft and take cuttings instead
This is why orchards are not raised from pits. To keep a known variety — its flavour, oil content and ripening time — growers propagate clones, either rooting cuttings under mist or grafting the desired variety onto sturdy seedling rootstock. That way every tree is a true copy of the parent and fruits far sooner: a grafted or cutting-grown tree typically bears in about three to five years, against seven to ten or more for a seedling. Growing from a pit is a lovely, patient experiment if you simply want an olive tree and do not mind a mystery, slow-to-fruit plant. If you want a specific variety, or olives this decade, start from a nursery cutting.
| From a pit (seed) | From a cutting/graft | |
|---|---|---|
| Comes true to variety? | No — reverts toward wild | Yes — an exact clone |
| Germination/rooting | Slow, patchy, stubborn | Reliable under proper conditions |
| Years to fruit | About 7-10+ | About 3-5 |
| What you get | A unique mystery tree | The named parent variety |
| Best for | Fun, curiosity, a pot plant | Actual fruit and a known variety |
So should you plant that pit?
By all means — as an experiment, not an orchard. A saved stone can make a handsome pot plant and children love watching it come up. Just do not expect it to be the olive you ate, and do not count on fruit any time soon, if at all. The moment you want a specific variety or a crop in a reasonable number of years, the honest answer is to skip the pit and buy a young grafted tree of a named variety. Patience is a virtue; a decade of waiting for mystery olives is optional.
Pit-planting, sensibly
- Plant a pit for fun — it makes a handsome pot plant and a great project for children.
- Expect it not to come true: the seedling will not be the variety you ate.
- Be ready for slow, patchy germination and a long wait — possibly a decade — for any fruit.
- For real fruit in a few years, buy a young grafted tree of a named variety instead.
Growing olives from a pit: common questions
Can you grow an olive tree from a pit?
Yes, but it is stubborn. The hard stone often needs cracking or a long soak, and germination is slow and patchy even then.
Will the tree be the same variety as the olive?
No. Olives do not come true from seed, so a seedling reverts toward the wild olive and gives a unique new tree, not the Kalamata or Picual you started with.
How long until a seed-grown olive fruits?
Often seven to ten years or more, and sometimes never in a cool climate — much slower than a grafted tree, which fruits in about three to five.
Why do growers use cuttings and grafting?
To keep a known variety exactly. A cutting or graft is a clone of the parent, so it fruits true and much sooner than a random seedling.
Is it worth planting an olive pit at all?
For fun, yes — it makes a lovely pot plant. For actual fruit or a specific variety, buy a young grafted nursery tree instead.
By all means plant a pit for fun — children love it and the seedling makes a handsome pot plant. Just go in clear-eyed: it may never fruit, and if it does, the olives will be its own, not the ones you ate. For actual fruit in a reasonable time, buy a young grafted tree of a named variety from a nursery. Patience is a virtue; a decade of waiting for mystery olives is optional.
