how to grow bonsai trees from seed

1. Check what your seed needs. Bald cypress: soak 24–48 hours, then stratify 2–3 months. Nordmann fir, Dawn redwood & Chinese elm: stratify 1–2 months. Japanese black pine: soak 24 hours, 1 month.
2. Stratify in a damp paper towel or moss in the fridge. See our seed prep guide.
3. Sow. Plant 1–2 seeds per soil pod, ⅛–¼" deep, in moist, well-draining mix.
4. Warm and bright. Cover with a humidity dome at 70–80°F in bright light.
5. Uncover and toughen up. Remove the dome after sprouting and give lots of light so seedlings don't stretch.

• Light: as much as possible: a sunny window, a grow light, or outdoors in summer.
• Water: keep consistently moist.
• Winter rest: both need a cool dormant period, ideally outdoors or in an unheated room.
• Feeding: diluted fertilizer every 2–4 weeks in the growing season.
• Shaping: start light pruning and wiring once the trunk thickens, usually year 2+.

Do I need to stratify bonsai seeds?

Yes! They usually won't germinate without a "winter".

Can I grow these bonsai indoors?

As seedlings, yes. Long term they need a cold winter rest.

Why did my tree lose its needles?

Many bonsai varieties are deciduous. It's normal in fall.

How long until it looks like a bonsai?

Usually 3–5 years of growing and shaping.
