FAQ

Is Tree of Heaven invasive?

In many regions Ailanthus altissima is listed as invasive because it spreads by root suckers and wind-borne seeds. Verify your municipal or state guidelines before planting, and remove volunteer seedlings promptly.

Do I really need to cold-stratify the seeds?

Yes. A two-month cold, moist stratification dramatically improves germination. Place seeds in damp sand or vermiculite inside a sealed bag at 2–5 °C / 35–40 °F.
