Pears from seed are a slow, hopeful project: the seed needs a long cold spell, germination takes 30–90 days, and the tree takes 3–6 years to mature — and like apples, pears do not come true from seed, so the fruit will be a surprise. But a packet of seed costs nothing, and a seedling pear makes a fine wildlife tree even if the fruit disappoints.
If you want a particular pear — a Bartlett, a Conference, a Comice — buy a grafted nursery tree. Seed is for the experiment. This guide covers the stratification, the slow germination, and the realistic timeline, so you start with your eyes open and do not lose a tray to impatience. Pears can be started indoors or direct-sown — its sowing method is listed as "both" — and indoor sowing is the better choice if you want an earlier start, more even germination, or plants ready for the first warm weeks of the season. This crop is in the Rosaceae family, needs full sun, and takes 1095–2190 days to reach maturity, so the timing below is built around those facts, not guesswork.

When to start pears seeds indoors
Start stratification in early winter, then sow indoors 12–16 weeks before your last frost. In Zones 3–5, grow seedlings on indoors until after the last frost and plant out in late spring. In Zones 6–8, plant out in spring or autumn. In Zones 9–10, autumn planting suits young trees. In frost-free Zones 11–13, pears struggle without winter chill — seed is an experiment there. Check your local extension service for frost dates, or use our frost-date calculator and seed-starting calculator.
As a rule, work backwards from your last frost: sow indoors 12–16 weeks before it if you are starting indoors at all, and check the seed packet against the germination time of 30–90 days. Our seed-starting calculator does the backwards maths for you, and the germination-time calculator helps you plan around that 30–90-day window. If you are unsure of your zone, the hardiness-zone finder will confirm it.
What you need
pear seed, a sealable bag and damp sand or peat for stratification, a seed tray or deep pots, seed-starting mix, a clear lid, a spray bottle, a grow light or bright windowsill, labels, and larger pots for potting on.
You will also want a spray bottle or a watering can with a fine rose, and a notebook to record the sowing date — germination takes 30–90 days, and it is easy to forget when you sowed.
Step by step: starting pears seeds indoors
- Fill your containers. Fill trays or pots with fresh, damp seed-starting mix — not garden soil, which is too heavy and can carry disease. Press it down lightly and level the surface.
- Sow the seed. Pear seed needs a long cold period: mix it with damp sand or peat in a sealed bag and refrigerate for 8–12 weeks, then sow shallowly in damp seed-starting mix. Germination takes 30–90 days and is slow and uneven. Keep the mix damp and the tray in bright light, and do not discard the tray early — late seeds do sprout.
- Cover and label. Cover the tray with a clear lid or cling film to hold humidity, and label it with the crop and the date. Put it somewhere warm and bright, out of direct sun until seeds sprout.
- Wait for germination. Germination takes 30–90 days. Check the tray daily, mist the surface if it dries, and be patient — uneven germination is normal, especially for slow crops. Our germination-time calculator helps you track the window.
- Remove the cover. As soon as seedlings emerge, take the lid off. Good airflow from this point on is what prevents damping off.
- Give them light. Move the tray under a grow light or to your brightest window immediately — seedlings stretch within a day or two if the light is weak.
- Thin and pot on. Thin to one seedling per cell once they have two true leaves, snipping the extras rather than pulling them. Pot on into larger pots when roots show at the drainage holes, keeping the seedlings at the same depth.
- Feed lightly. Once seedlings have two sets of true leaves, feed with a half-strength liquid feed every week or two. Do not overfeed — soft, overfed seedlings are more likely to damp off and less likely to harden well.
Light for seedlings
Give pear seedlings 14–16 hours of bright light a day. A grow light a few inches above the leaves keeps them compact; a sunny windowsill works once they are up. Weak light produces tall, floppy seedlings.
Watering seedlings
Pears have moderate water needs. Keep the mix evenly moist while seeds germinate — a tray that dries out during the long germination period loses the seed — then water from below and let the surface dry slightly between waterings. Our watering calculator can help you work out how much water your seedlings need as they grow.
Hardening off
Pears are hardy, but seedlings need a gentle introduction: 10 days of increasing outdoor time, starting in sheltered shade and building to full sun. Do not plant out until seedlings are sturdy.
Transplanting outdoors
Grow seedlings on in pots for their first season, then plant out in full sun, in soil pH 6.0–6.5. Space trees 120–180 inches apart — a seedling pear becomes a full-size tree. Our plant-spacing calculator works out the layout. Protect young trees from rabbits and deer with a guard, and stake them for the first year.

Common problems and fixes
| Problem | Fix |
|---|---|
| Seeds never germinate | Pear seed needs 8–12 weeks of cold stratification, then 30–90 days in damp mix. Without chilling, germination is poor. Keep the mix damp throughout. |
| Leggy seedlings | Not enough light. Move the grow light closer and give 14–16 hours a day. |
| Damping off | Seedlings collapse at the base. The mix was too wet. Water from below and remove the lid once seeds sprout. |
| Seedlings eaten after transplanting | Rabbits and deer love young pear shoots. Use a tree guard until the tree is established. |

Good companions for pears include borage, marigolds, clover, chives. Watch out for aphids, Japanese beetles, birds, spider mites — check young plants regularly, and deal with pests early while plants are small. Our pest-identifier helper can help you work out what you are looking at.
Frequently asked questions
How long do pear seeds take to germinate?
30–90 days after 8–12 weeks of cold stratification in the fridge.
Will a seed-grown pear taste like the parent?
No — pears do not come true from seed. Buy a grafted tree if you want a specific variety.
Is it better to buy a pear tree instead?
For fruit, yes — a grafted nursery tree fruits sooner and is true to variety. Seed is a slow experiment.
How far apart should pear trees be?
120–180 inches apart in full sun, in soil pH 6.0–6.5.
When will a seed-grown pear tree fruit?
Pears take 1095–2190 days to mature, so expect fruit in 3–6 years.
