Mid-Season Check-In: Filling the Gaps with Low-Maintenance Native Plants
The Mid-Season Landscape Review
We’re well into the growing season, and now is the perfect time to take a walk through your garden with fresh eyes. Notice what’s thriving, where the color and texture are strong, and—just as importantly—where the gaps have appeared. This mid-season evaluation helps you choose plants that will fill in weak spots, extend bloom times, and keep your landscape low-maintenance yet beautiful all year long.
Whether you’re in the heart of Philadelphia or along the Main Line, this is the season to make smart, lasting plant additions that align with sustainable landscape design trends and your home’s unique style.
Designing for Year-Round Structure and Beauty
A balanced, low-maintenance landscape in our region needs four layers: evergreen trees, evergreen shrubs, flowering shrubs, and perennial color. By mixing structure with seasonal interest, you create a garden that supports pollinators, weathers drought, and looks good in every month of the year.
