Do you want to grow a certain plant in your garden, but it’s not quite hardy in your Zone? Aside from overwintering it indoors, you can try growing it in a microclimate in your yard.
Here’s how to identify warm microclimates in your landscape:
• These “heat islands” can be on the south-facing side of your home,
at the foot of a stone wall or in nooks among large rocks.
• Look for areas that are well-drained (especially in winter).
• When you’ve found a promising location, mount a thermometer on a stake,
one to two feet tall. Record the temperature right before sunrise, which is
the coldest time of day.
• Repeat in other areas of your yard. This way you’ll find the warmest
locations for planting.
