Pacific Sunset Maple

Acer  x Pacific Sunset, also known as ‘Warrenred’


This is a vigorous, smaller maple tree that does not need a huge area to grow in. It will form a spreading tree with attractive, dark green leaves that turn yellow to red in the fall. It is tougher than most maples and resists pests and diseases.


It is happy in a lawn or garden that receives moderate water.


Note that any tree grown in a lawn may develop surface roots unless irrigation is properly managed. Tree roots need both air and water in the root zone. Lawns are frequently overwatered, resulting in water-logged soil with no air in the root zone. Check your tree’s root zone to see if it is water-logged or too dry. The best method is to dig a small hole about 12 inches deep and look at the soil: if it is bone dry, there is not enough water; if it is muddy, there is too much water; if it is moist like a cake, it is just right. Alternatively, you can use an inexpensive moisture meter from your nursery or hardware store and look for a “moist” reading.
