Growing fruit from seed is a pleasure and a gamble in equal measure. The pleasure is obvious: a seed costs nothing, a seedling is a small miracle, and a tree you grew from a pip is yours in a way a bought tree never is. The gamble is that most fruit does not grow true from seed. An apple pip does not grow into the tree its apple came from — it grows into a new, unknown apple, which may be sour, small or wonderful, and which will take years to tell you which. That is how new apple varieties are born, and it is why seed-grown fruit is a project for the patient and the curious, not a shortcut to a harvest.
Some fruit does grow well from seed. Strawberries, melons and many berries grow true enough from seed to be worth sowing, and they fruit quickly — strawberries in their first year, melons in their first summer. Citrus grown from seed will fruit, but slowly, and it may take many years. Apples, pears, peaches, plums and cherries grown from seed will fruit eventually, but the fruit will be a surprise, the tree will be full-size, and it will take five to ten years to find out what you have. For a reliable harvest of a known variety, buy a grafted tree — that is what grafting is for.
If you do grow fruit from seed, the key technique to learn is stratification: the cold, damp period many fruit seeds need before they will germinate. In nature, a pip falls in autumn, spends winter cold and damp in the soil, and germinates in spring. To copy that, you chill the seed in damp compost in the fridge for weeks or months before sowing. Skip the chill, and most apple, pear, peach and cherry seeds simply will not germinate. If you are unsure about a variety, a spray, or a diagnosis, check your local extension service — its advice is matched to your climate and soil.
Which fruit is worth growing from seed
Strawberries are the best fruit to start from seed: sow alpine strawberries indoors in late winter, and they will fruit in their first year, in small pots, with very little space. Melons are sown indoors in spring and fruit in their first summer — they are fast, warm and satisfying, and seed is the only sensible way to grow them. Raspberries and blackberries can be grown from seed, but they are slow and variable, and a bought cane fruits years sooner. Blueberries can be grown from seed, but they are very slow and need acidic soil from the start, so a bought bush is a better investment. Apples, pears, peaches, plums and cherries from seed are a long-term experiment: the tree will be full-size, the fruit will be unknown, and you will wait five to ten years to taste it. That is a fine project if you enjoy the experiment, and a poor plan if you want a known variety and a reliable harvest. Citrus from seed is a middle case: it will fruit, it will be true enough to be recognisable, but it may take seven years or more and it may be thorny and vigorous. Our seed starting calculator can help you time any sowing from your last frost date.
Stratification: the cold treatment fruit seeds need
Stratification is the process of giving a seed the cold, damp winter it needs before it will germinate. For apples and pears, mix the seeds with damp compost or sand in a sealed bag, keep it in the fridge for eight to twelve weeks, and check it weekly for mould and for germination — some seeds will sprout in the bag. For peaches, plums and cherries, the seed is inside a hard stone: crack the stone gently or sow the whole stone in a pot outdoors in autumn and let winter do the work, which is simpler and often more successful than the fridge method. For grapes, stratify the seeds for two to three months in the fridge. Strawberries need no stratification, but they germinate better if the seed is chilled for a week or two first. Melons, figs and citrus need no stratification at all — they are warm-climate fruit and germinate in warmth. The seed viability checker can help you test whether old seed is still worth sowing, and the germination time calculator can tell you how long to expect to wait.
Sowing fruit seed indoors step by step
Sow fruit seed in a free-draining seed compost, in pots or modules, and cover the seed with its own depth of compost — tiny strawberry seed is barely covered at all, while a peach stone is sown an inch deep. Water from below or with a fine spray, so you do not wash the seed out, and cover the pot with a clear lid or a plastic bag to hold the humidity. Keep the pot warm for melons, citrus and figs — a warm windowsill or a heated propagator — and cool for apples and pears after stratification, because they germinate best in cool spring conditions. Give the seedlings as much light as you can as soon as they appear, and remove the cover once they are up, so the air circulates and damping off does not strike. Damping off is the seedling disease that makes stems collapse at soil level, and it is caused by wet, still, cold conditions — the cure is airflow, light and not overwatering. Prick the seedlings out into individual pots when they have two true leaves, handling them by a leaf, never by the stem.
Growing on: from seedling to young plant
A fruit seedling grows slowly at first and then fast, and the first year is about roots, not fruit. Pot the seedling on into a larger pot whenever the roots fill the one it is in, feed it lightly with a balanced liquid feed through the summer, and keep it watered but not wet. Harden the seedling off before putting it outside: a week of increasing time outdoors, starting in shade and ending in full sun, so the leaves do not scorch and the plant does not check. For strawberries and melons, the seedling goes into its final position in late spring, after the last frost, and fruits in its first year. For a tree seedling, keep it in a pot for its first year, plant it out in its second spring, and protect it from rabbits and deer with a guard — a young tree is a tasty snack. Do not expect fruit for years, and do not judge the seedling by its first fruit: the first crop is often small and poor, and the tree improves as it matures. If you want fruit sooner, graft a known variety onto your seedling once it is big enough — the seedling makes a fine rootstock.
Seed-grown fruit versus grafted trees
A grafted tree is a known variety joined to a chosen rootstock, and it is the only way to guarantee the fruit you want, the size you want, and fruiting in two to three years. A seedling is a genetic lottery: it may be better than its parent, it will probably be worse, and it will certainly be different. That is why commercial orchards never grow from seed, and why a home grower who wants a particular apple should buy a grafted tree. But the lottery has its own rewards: every named apple variety in existence began as a seedling someone noticed, and a seedling apple that turns out to be a good cooker or a good eater is a genuine discovery. The sensible approach is to do both: buy grafted trees for the harvest you rely on, and grow a few seedlings on the side for fun. Keep a label on every seedling with the parent variety and the sowing date, because in five years you will not remember what it was.
Common seed-starting mistakes with fruit
The commonest mistake is sowing without stratification and concluding the seed was dead — apple, pear, peach and cherry seed needs its cold period, and without it, it will sit and do nothing. The second is sowing too early: a melon sown in January grows leggy and weak long before it can go outside, while a melon sown in April is strong and ready at the right time. The third is overwatering, which rots the seed before it germinates and causes damping off after it does. The fourth is not enough light: a seedling on a dark windowsill stretches towards the light and falls over, and no amount of later care will fix a leggy seedling. The fifth is impatience with trees: a seedling apple that has not fruited in three years is not a failure, it is a young tree, and it may need five more years. Sow at the right time, keep the seed moist but not wet, give the seedling all the light you can, and let the tree take its time.
Frequently asked questions
Can I grow an apple tree from a pip?
Yes, but the fruit will not be the same as the apple the pip came from — it will be a new, unknown variety, and the tree will be full-size and take five to ten years to fruit. For a known variety, buy a grafted tree.
Do apple seeds need cold before they germinate?
Yes. Apple and pear seeds need eight to twelve weeks of cold, damp stratification — in the fridge in damp compost — before they will germinate. Without it, they usually will not sprout.
What fruit grows best from seed?
Strawberries and melons are the best: strawberries fruit in their first year and melons in their first summer. Citrus grows from seed but takes many years to fruit.
When should I sow melon seeds?
Indoors in spring, a few weeks before the last frost, so the plants are strong and ready to go outside when the weather warms. Melons sown too early grow leggy indoors.
Why did my fruit seedlings collapse at soil level?
That is damping off, a fungal disease caused by wet, still, cold conditions. Give seedlings light and airflow, water from below, and do not overwater.
Fruit from seed is a slow pleasure, and the best way to enjoy it is to be clear about what you are doing: sow strawberries and melons for a harvest, and sow apples and peaches for the experiment. Buy grafted trees for the fruit you rely on, and let the seedlings surprise you. For timing, use the seed starting calculator, and for the individual fruits, see the growing guides.
