Garden Microclimates: Shrug Off Your Growing Zone

Ignore those Zone limitations and find areas in your garden where traditional growing advice doesn’t apply.

When I worked as a commercial gardener, one of the most interesting things I learned about was the influence of microclimates. Even though all the gardens I maintained were within 30 miles of each other, I soon discovered that what grew well in one garden was no sure indicator of what could be persuaded to thrive in another — even when the other garden was right next door! Conventional wisdom states that what a gardener can grow is limited by the USDA Hardiness Zone they’re gardening in, but I’ve found that isn’t the whole truth. Another important factor should also be taken into consideration: every garden’s unique microclimates.

Season extenders, such as row covers, are invaluable for warming up soil and protecting crops from the elements, but smart gardeners can deploy many more powerful techniques. By becoming aware of and manipulating the microclimates that make up your plot, you can improve yields and successfully grow crops that are on the borderline of what’s feasible in your region.
