Planting Sprouted Lemon Seeds: Potting, Light, and Acclimation

From Sprouted Seed to Healthy Lemon Seedling

If your lemon seeds have already sprouted (radicle visible), plant them promptly for best results.

Potting Up

1. Use individual 4–6 inch pots with well-draining citrus potting mix.
2. Fill to 2 inches below rim.
3. Place sprout on soil surface, root down; cover gently with ½–1 inch (1.5–2.5 cm) of soil.
4. Water thoroughly; keep evenly moist but not soggy.

Light and Temperature

• Place in an east- or south-facing window for maximum light.
• Supplement with fluorescent shop lights if natural light is low.
• Maintain 65–75°F (18–24°C).

Moving Outdoors

1. Wait until nights are consistently above 50°F (10°C).
2. Harden off: place in shade for 10 days, gradually increasing sun exposure.
3. Bring indoors before any frost threat.

Long-Term Notes

Seed-grown lemons take 5+ years to fruit and may not match the parent variety. For faster, reliable fruit, buy a grafted dwarf cultivar.
