Summer Heat vs. Japanese Maple Trees

In today’s podcast, nurseryman and Japanese maple expert Chris Aycock of El Dorado Nursery provides the basics for Japanese maple care, especially in the summer months.

Chris focuses on growing Japanese maples in different climates, explaining that the main factor is matching varieties to local conditions and caring for them appropriately.

For hot valley areas, he says mulch is very important to keep roots cool, and morning sun with afternoon shade is ideal. He also notes that some varieties can handle full sun, but they should be planted away from hot walls because reflected heat can be harmful.

For coastal areas, he says Japanese maples can grow well as long as they are not hit directly by sea spray. In windy, hot, dry inland areas, he says wind can be more damaging than sun, so some protection from afternoon wind is recommended.

At higher elevations such as Lake Tahoe (6200 ft), he says Japanese maples can be grown but may need protection from heavy snow load. He notes that some varieties do not perform well in intense cold, while others, including laceleaf types and Bloodgood, have been seen there.
