Even though Portland area skies are still cold, wet and grey, it won’t be long before we see signs of spring in the trees.

Why Don’t Trees Freeze?

January 25, 2021 By

Outdoor winter temperatures in the Portland area regularly fall below the fresh water freezing temperature of 32 degrees Fahrenheit.

Shade Trees

When our mild Portland temperatures turn hot in late summer, a well-placed shade tree can significantly reduce the temperature of shaded homes and outdoor gathering areas. Shade trees cool by deflecting heat instead of absorbing it and by releasing water vapor from the undersides of their leaves. If you would like enjoy the benefits of more shade in your yard,...

July 23, 2020 By ,

Our dry northwest summers motivate many urban gardeners to water their trees to excess. Overwatering is a common cause of urban tree decline.
