Propagating Florida Sycamore from Seed: Simple Steps

Sycamore (Platanus occidentalis) seeds need no stratification—nature handles it.

Seed Collection & Sowing

1. Collect seed balls in fall/winter when they break apart.
2. Separate tiny, hairy seeds (achenes) from fluff.
3. Sow ⅛ inch deep in moist potting mix.
4. Keep at 75°F. Germination starts at 14 days, continues weeks.

Notes

• Viability varies—poor pollination = empty seeds. Sow heavily.
• No cold treatment needed.
• Spring sowing aligns with natural cycle.

Seedling Care

• Prick out at 2–3 true leaves; pot individually.
• Harden off 10 days in shade after last frost.
• Full sun, moist soil, grows fast.

Easy, reliable, and great for shade or restoration.
