Frequently asked questions

When is Fall?

Astronomical fall in the Northern Hemisphere begins around September 22–23, at the autumn equinox.

Why do leaves change color in the fall?

As daylight shortens, trees stop producing chlorophyll (the green pigment). With the green gone, the yellows and oranges that were always in the leaf show through, while sugars trapped in some species produce brilliant red anthocyanins.
