Planting and Care Tips

Low-maintenance does not mean “no maintenance.” To help your trees and shrubs thrive:

Mulch with compost each spring for moisture retention and weed control.

Water consistently until roots are established (first one to two years), then only during prolonged droughts.

Prune annually to maintain shape and remove damaged or diseased branches.

Choose locations with appropriate sunlight and soil types as advised for each species.

Native species are particularly resilient, adapting to southern Ontario’s climate and often surviving on rainfall alone after initial establishment. Grouping plants with similar water and light needs further reduces ongoing effort.

For southern Ontario homeowners, choosing low-maintenance trees and shrubs means more time relaxing and less time working outdoors. Native options like Red Maple, White Spruce, Serviceberry, and Nannyberry offer year-round beauty and ecological benefits. Evergreen choices such as Dwarf Alberta Spruce and Eastern Red Cedar supply reliable structure. Hardy shrubs like Boxwood, St. John’s Wort, Dogwood, and Witch Hazel require few interventions and help gardens look healthy even during the toughest seasons.

With careful selection and a few simple care routines, it’s easy to cultivate a vibrant, low-maintenance landscape that enhances property value and supports local biodiversity
