Growing Japanese Maples in Zone 7
As a rule, Japanese maple trees are hardy in zones 5 through 9. Not all can tolerate zone 5 minimum temperatures, but basically all can survive a zone 7 winter. This means that your options when selecting zone 7 Japanese maples are virtually limitless…as long as you’re planting them in the ground. Since they’re so showy and some varieties stay very small, Japanese maples are popular container trees. Since roots planted in a container are separated from the cold winter air by just a thin piece of plastic (or other material), it’s important to choose a variety that can take much colder temperatures. If you’re planning on overwintering anything outdoors in a container, you should choose a plant rated for two whole hardiness zones colder. That means that zone 7 Japanese maples in containers should be hardy down to zone 5. Luckily, this covers a lot of varieties.
