A cherry pit can absolutely produce a living cherry tree, and people have been doing it for centuries. The catch is that the tree you grow will almost certainly not produce fruit identical to the cherry you ate. Cherry trees grown from seed are genetic wildcards, and understanding why requires a look at how these trees reproduce, what they need to germinate, and why commercial orchards rely on grafting instead. Still, growing a cherry tree from a pit is a rewarding project, and the tree you end up with may surprise you in good ways.
Why the Fruit Will Not Match the Parent
Every cherry pit contains a seed that is genetically unique. Sweet cherries in particular are highly heterozygous, meaning their DNA carries a wide mix of gene variants from both parents. When you eat a Bing cherry and plant the pit, the resulting seedling is not a clone of the Bing tree. It is the offspring of the Bing tree and whichever tree provided pollen, and the genetic shuffle that happens during sexual reproduction means the seedling could express traits from either parent or from grandparents further back in the lineage.
Research on Scandinavian sweet cherry accessions illustrates this clearly. When trees were assessed in their original growing locations, they clustered by country of origin in terms of visible traits. But when seeds from those same trees were grown out at a single site in Denmark, the resulting seedlings no longer matched the trait patterns of their parents. The researchers concluded that the appearance and fruit quality of seed-grown cherry trees depend on a tangled interaction between the new seedling’s unique genotype, its growing environment, and the unpredictable genetic recombination that comes with open pollination.1Scientia Horticulturae. In situ and ex situ assessment of morphological and fruit variation in Scandinavian sweet cherry
In practical terms, your pit-grown cherry tree might produce fruit that is smaller, less sweet, differently colored, or shaped nothing like the cherry you planted. It could also, on occasion, produce fruit that is perfectly good or even interesting in its own right. You simply cannot predict what you will get. This is the fundamental reason nurseries do not sell seed-grown sweet cherry trees for fruit production.
The Self-Incompatibility Problem
Even if your seedling grows into a healthy tree and eventually flowers, getting it to set fruit introduces another complication. Most sweet cherry varieties are self-incompatible, meaning a tree cannot pollinate itself. The pollen and the pistil recognize each other as genetically too similar and the fertilization process is blocked at a molecular level.
Researchers examining the sweet cherry variety Tieton found a self-pollination fruit set rate of just 2%, compared to 56% when pollen came from a compatible partner variety.2PubMed Central. Identification of Self-Incompatibility Related Genes in Sweet Cherry Based on Transcriptomic Analysis That is not an unusual result for sweet cherries. The incompatibility is governed by a set of genes called S-alleles, and decades of research have identified at least 17 pollen incompatibility groups among cultivated sweet cherry varieties.3Euphytica. Identification of self-incompatibility alleles and pollen incompatibility groups in sweet cherry PCR based S-allele typing and controlled pollination
What this means for you: a single cherry tree grown from a pit, standing alone in your yard, will likely produce few or no cherries unless another compatible cherry tree is blooming nearby. You have no way to know in advance which incompatibility group your seedling belongs to, so even if you plant two seedlings side by side, there is no guarantee they will be compatible with each other. Some newer self-fertile varieties (like Stella and Lapins) exist in the nursery trade, but those traits are maintained through grafting, not seed.
What Cherry Pits Need to Germinate
Cherry seeds will not sprout if you simply stick them in soil after eating the fruit. Like many temperate fruit trees, they require a prolonged period of cold and moisture before the embryo inside will wake up. This process, called cold stratification, mimics the natural winter the seed would experience on the ground beneath a parent tree.
The practical method is straightforward. Clean all the fruit flesh off the pit, since residual pulp can encourage mold. Place the cleaned pits in a damp (not soaking) medium like peat moss, sand, or a wet paper towel inside a sealed plastic bag, and refrigerate for roughly 8 to 12 weeks. Temperatures around 1 to 5°C (34–41°F) work well. Check periodically for mold and keep the medium moist. After the stratification period, some pits will have already cracked open and begun to show a tiny root. Plant those immediately in pots with well-draining soil, about an inch deep, and keep them in a bright, cool spot.
Not every pit will germinate. Germination rates for cherry seeds are notoriously variable and depend on the variety, the freshness of the seed, and how well the stratification period went. Starting with several pits improves your odds. You can also gently crack the hard outer shell of the pit (without damaging the seed inside) before stratification to speed water uptake, though this takes a careful hand and a nutcracker.
An Interesting Wrinkle From Nature
In the wild, cherry seeds often germinate after passing through the digestive tract of birds or mammals. Research on black bear digestion found that for several fruit species, seeds that had passed through a bear’s gut germinated at rates comparable to seeds that were carefully cleaned by hand. Both treatments performed far better than seeds left inside their fruit pulp. The conclusion was that the main benefit of animal ingestion is pulp removal rather than any chemical effect of digestion on the seed coat itself.4BioOne Complete. It is Good to be Eaten by a Bear: Effects of Ingestion on Seed Germination This underscores why thoroughly cleaning the pit before stratification matters so much. The pulp is not just a nuisance; it actively inhibits germination.
Chill Hours and Where Cherry Trees Can Grow
Getting a pit to sprout is one thing. Growing the seedling into a tree that thrives and eventually flowers is another, and climate is the biggest limiting factor. Cherry trees need a substantial winter cold period every year, not just as seeds but as mature trees. Without enough accumulated “chill hours” during dormancy, the tree will not flower properly in spring, which means no fruit.
How much cold a cherry tree needs varies by variety. Research on cherry cultivars found that minimum chill requirements ranged from around 400 chilling hours for low-chill varieties up to 750 or more for high-chill types.5Scientia Horticulturae. Substitution of winter chilling by spring forcing for flowering using sweet cherry as model crop A chilling hour is generally counted as one hour at a temperature between 0 and 7°C (32–45°F). Some models use more complex calculations. A detailed study of one German cherry cultivar calculated its chilling requirement at roughly 1,375 chilling hours.6PubMed Central. Identification of chilling and heat requirements of cherry trees–a statistical approach
If you live in a region with mild winters (USDA zones 9 and 10, most of the subtropics), a cherry tree from a pit will likely grow into a tree but never produce meaningful bloom or fruit. The best climates for cherry trees are those with cold, distinct winters and moderate summers, roughly USDA zones 4 through 7 for sweet cherries and slightly broader for sour cherries, which tend to be hardier. Sour cherry varieties also tend to have lower chill requirements and are more often self-fertile, making them a more forgiving choice for a pit-growing experiment.
After the chilling requirement is met, cherry trees also need a certain accumulation of warm temperatures (growing degree hours) in spring to push through bud break and flowering. Varieties that need very little chill but a large amount of spring warmth may still fail to flower properly if your spring weather is cool and lingering. Temperature extremes after bloom, including late frosts, are also a significant risk for fruit set.
Why Commercial Orchards Use Grafting Instead
If you have ever bought a cherry tree from a nursery, it was almost certainly a grafted tree. Grafting involves attaching a cutting (the scion) from a known, desirable variety onto the root system (the rootstock) of a different, often hardier or size-controlling tree. The scion grows into the canopy and produces fruit true to its variety, while the rootstock controls the overall size of the tree and its tolerance for local soil and climate conditions.
Grafting solves the two biggest problems with seed-grown trees at once. First, it guarantees the fruit variety. A Bing scion grafted onto a Mazzard rootstock will produce Bing cherries, period. Second, it controls tree size. Ungrafted sweet cherry trees can grow well over 20 metres tall, making harvesting impractical and crowding other trees.7Current Biology. Plant grafting Dwarfing and semi-dwarfing rootstocks keep orchard trees at manageable heights, typically 3 to 5 metres.
A seed-grown cherry tree, by contrast, will grow on its own roots and can become enormous. It will also take longer to produce its first fruit, often 7 to 10 years compared to 3 to 5 for a grafted tree. If you are growing a cherry pit for fun, as a shade tree, or as a rootstock onto which you might later graft a known variety, these are not necessarily drawbacks. But if your goal is reliably delicious fruit within a few years, buying a grafted tree is the sensible path.
Disease Risk From Seed-Grown Trees
One concern that rarely comes up in casual gardening advice is the possibility of viral transmission through seeds. Most plant viruses spread through insects, pruning tools, or grafting with infected material. But recent research from Bulgaria documented that Cherry Virus A (CVA) was detectable in seeds collected from naturally infected sweet cherry trees, and that seedlings grown from those seeds also carried the virus. This was the first confirmed evidence of vertical (parent-to-offspring) transmission of CVA in sweet cherry.8Plant Health Progress. A Survey on the Occurrence and Seed Transmission of Cherry Virus A in Sweet Cherry in Bulgaria
For the home grower planting a pit from a supermarket cherry, the practical risk is low. CVA and similar viruses are primarily a concern for nurseries and orchards, where infected rootstock or seedlings can spread disease through an entire operation. But it is worth knowing that “grown from seed” does not automatically mean “disease-free,” especially if the parent tree was in a region with known viral infections.
Sour Cherries Versus Sweet Cherries
Most people think of sweet cherries (Prunus avium) when they picture growing a tree from a pit, but sour cherries (Prunus cerasus) are often a better candidate for the experiment. Sour cherry trees are generally smaller, hardier, more tolerant of a range of soils, and more likely to be self-fertile. A single sour cherry tree in your yard has a realistic chance of setting fruit without a pollination partner nearby.
Sour cherries also tend to come somewhat truer from seed than sweet cherries, though “somewhat” is doing a lot of work in that sentence. You will still get genetic variation, but sour cherry genetics are less wildly heterozygous than sweet cherry genetics, in part because Prunus cerasus is an allotetraploid (it carries four sets of chromosomes rather than two). The offspring may be more recognizably sour cherries, even if they differ from the parent in size and flavor.
If your goal is a backyard tree that will actually produce usable fruit for pies, jams, or preserves, starting with a sour cherry pit is a more forgiving route. The fruit of seedling sour cherry trees is often perfectly serviceable for cooking, even if it would not win a beauty contest at a farmers’ market.
How Long Until You See Fruit
Patience is the price of growing a cherry tree from a pit. After stratification and germination, you will have a small seedling that needs careful attention for its first year or two: consistent watering, protection from hard freezes, and gradual hardening off before transplanting outdoors. Once in the ground, the seedling will spend several years building its root system and canopy before it is mature enough to flower.
Sweet cherry seedlings typically need 7 to 10 years from germination to first fruit, and some take longer. Sour cherry seedlings tend to be a bit quicker, often fruiting in 5 to 7 years. These timelines assume the tree is getting adequate sunlight (at least 6 to 8 hours of direct sun daily), decent soil drainage, and enough winter chill. A tree planted in marginal conditions may grow slowly and delay fruiting further.
The first few years of fruit production are often light and inconsistent. The tree is still maturing, and factors like spring frost, poor pollination, and environmental stress from high temperatures after harvest can all reduce fruit set.9PubMed Central. Influence of Regulated Deficit Irrigation and Environmental Conditions on Reproductive Response of Sweet Cherry Trees By the time your tree is reliably producing a full crop, you may have been tending it for over a decade. That is a genuine commitment, but there is something uniquely satisfying about eating fruit from a tree you grew from a pit you pulled out of your mouth.
When Cherry Trees Become Invasive
A related question that backyard growers rarely consider is whether their cherry tree could become an ecological problem. For most sweet and sour cherry seedlings in a residential setting, the answer is no. But some cherry species, particularly black cherry (Prunus serotina), are aggressive colonizers in certain environments. In parts of Europe, black cherry has become a serious invasive species in Scots pine forests, spreading rapidly once a sufficient base of seed-producing trees establishes itself in an area. Research on the spatial genetics of this spread found that invasive success is strongly tied to the availability of seeds (propagules) and landscape features that either speed or slow colonization.10Silva Fennica. Spatial genetic structure and clonal structure of Prunus serotina during invasive spread
Sweet cherry (Prunus avium) can also naturalize in some regions, though it is less aggressively invasive than black cherry. Birds are the primary dispersal agents, eating the fruit and depositing seeds far from the parent tree. If you are growing a cherry seedling in a region where Prunus species are listed as invasive or potentially invasive, it is worth checking with local extension services. In most of North America, a single backyard sweet or sour cherry tree is not going to cause ecological harm, but awareness of the broader pattern is worthwhile, especially in areas near natural forests or conservation land.
Using Your Seedling as Rootstock
One of the most practical uses for a pit-grown cherry tree is as rootstock for grafting. If you grow a healthy seedling for two or three years and it develops a sturdy trunk, you can graft a scion from a known cherry variety onto it. This gives you the best of both worlds: a tree that is uniquely adapted to your soil and microclimate (since it grew from seed in your yard) with a canopy that produces a predictable, named variety of fruit.
Mazzard cherry (a strain of Prunus avium) has historically been the most common seedling rootstock for sweet cherry grafting, valued for its vigor and compatibility with most sweet cherry varieties. If you happen to have planted a sweet cherry pit, your seedling may function well as a Mazzard-type rootstock. Grafting is a learnable skill, and chip budding in late summer is the technique most commonly used for cherry trees. Plenty of extension resources walk through the process step by step, and the tools needed are minimal: a sharp grafting knife, some grafting tape, and a scion stick from a tree you admire.
The tree will still grow to full size on seedling roots unless you specifically chose a dwarfing rootstock to start with. But for a home grower with space, a full-size cherry tree on its own roots can be a magnificent landscape specimen that also produces excellent fruit, provided the graft takes and the scion variety is suited to your climate.
