Steps
Fill small pots or a seed tray with moist seed starting mix. Press it down lightly so the surface is level and firm.
Scatter the tiny coleus seeds thinly on the surface. Do not bury them, because they need light to germinate.
Mist the surface with water from a spray bottle so the seeds settle without washing away.
Cover the tray with a clear lid or plastic wrap and keep it warm, around 70 to 75 F. Vent it once a day.
Place the tray in bright, indirect light. Remove the cover once seedlings are up, usually in 10 to 21 days.
Keep the mix evenly moist but not soggy. Water gently at the base so the tiny seedlings do not fall over.
When seedlings have two or three sets of true leaves, thin them or move each one into its own small pot.
Give the young plants plenty of light, such as a south or west window or a grow light for 12 to 14 hours a day.
Repot into a bigger container once roots fill the pot. Use fresh potting mix and water well after potting.
Tips and common mistakes
Coleus seeds need light to sprout, so never cover them with soil.
Leggy seedlings are reaching for light, so move them closer to a window or grow light.
Pinch off the growing tips to make the plant bushier instead of tall and thin.
Check the soil every few days, since small pots dry out fast on a warm windowsill.
Questions
How long do coleus seeds take to germinate?
Most sprout in 10 to 21 days when kept warm and moist in bright light. Cooler rooms slow them down.
Can coleus grow indoors all year?
Yes, with enough light. A bright window or grow light keeps the foliage colorful through winter.
Should I remove the coleus flowers?
You can leave them, but pinching them off keeps the plant focused on leaf growth and a fuller shape.
