Landscaping glossary

Homeowners mix these terms up all the time. Here are the plain-English definitions.

Lawn care
Ongoing maintenance of an existing lawn — mowing, fertilizing, aeration, weed control, seeding.
Landscaping
Adding or changing living things in the yard — planting beds, trees, shrubs, borders, yard-wide design.
Hardscaping
Anything non-living and permanent — patios, walkways, walls, fire pits, stone, brick, concrete.
Grading
Shaping the dirt so water flows away from your house. Fixes wet basements and boggy yards.
Aeration
Pulling small plugs of soil out of the lawn to relieve compaction and let air, water, and nutrients reach roots.
Mulch
Organic layer (usually shredded hardwood) around plants. Retains moisture, moderates soil temp, suppresses weeds.
USDA Hardiness Zone
Cold-hardiness rating that tells you if a plant will survive a typical winter. Crystal Lake is Zone 6a (–10°F to –5°F average annual extreme low) under the 2023 USDA map; pre-2023 references called it Zone 5a.
French drain
Perforated pipe in a gravel trench that collects and redirects groundwater. Fixes chronic wet spots.
