With winter lows of 0 to 10 degrees F. (-18 to -12 C.), zone 7 gardens have many options of edibles to grow in the garden. We often think of garden edibles as only fruits and vegetable plants and overlook the fact that some of our beautiful shade trees also produce nutritious nuts that we could be harvesting. For example, acorns were once a staple food for many Native American tribes. While most recipes these days don’t call for acorns, there are many other edible nut trees that we can add to the landscape. This article will discuss what nut trees grow in zone 7.
About Zone 7 Nut Trees
The hardest thing about growing nuts in zone 7, or anywhere, is having patience. Different kinds of nut trees can take several years to mature enough to bear nuts. Many nut trees also require a pollinator to produce fruit. So, while you may have a hazelnut tree or pecan tree in your yard, it may never produce nuts if there isn’t a compatible pollinator nearby.
Before purchasing and planting zone 7 nut trees, do your homework so you can select the best trees for your specific needs. If you plan to sell your home and move in the next five to ten years, it won’t do you much good to plant a nut tree that can’t produce nuts for 20 years. If you have a small urban yard, you may not have the room to add two large nut trees, as required for pollination.
