Okanagan winters can be hard on landscapes. Snow, freezing temperatures, fluctuating weather, and spring snowmelt all affect lawns, garden beds, irrigation systems, patios, walkways, and retaining walls.
A little preparation in fall can reduce winter damage and make spring cleanup much easier. The goal is not to make the yard look perfect before snow arrives. It is to protect the systems and materials that support a healthy, functional landscape.
1. Complete a Final Yard Inspection
Walk through the property before temperatures drop and look for drainage problems, loose pavers, damaged edging, unstable branches, clogged drains, and areas where soil or mulch has washed away.
Fall is also a good time to observe where rainwater travels. Water flowing toward the house, collecting on a patio, or pooling above a retaining wall should be addressed before snow and ice make the area harder to inspect.
2. Remove Leaves and Organic Debris
A light layer of shredded leaves can benefit some garden beds, but thick, wet piles can smother grass, trap moisture, and create slippery hardscape surfaces.
Remove leaves from lawns, patios, walkways, drains, window wells, and areas where runoff must flow freely. Healthy leaves may be composted or used appropriately as mulch, provided they are not diseased.
3. Give the Lawn a Proper Final Cut
Continue mowing while the grass is actively growing. The final cut should leave the lawn tidy without scalping it. Grass left excessively long may mat beneath snow, while grass cut too short has less leaf surface and protection.
Aeration or fall fertilization may be appropriate depending on the lawn’s condition, timing, and turf type. Avoid heavy traffic when the soil is saturated or frozen.
4. Prepare Garden Beds
Remove diseased plant material, invasive weeds, and annuals that have finished for the season. Some healthy perennial stems and seed heads can remain to provide winter interest and habitat.
Apply mulch where needed to moderate soil temperature and protect roots. Keep mulch away from direct contact with trunks, woody stems, and the home’s exterior.
New plantings should enter winter well watered, but the soil should not remain waterlogged.
5. Protect Trees and Shrubs
Inspect trees and shrubs for broken, rubbing, or hazardous branches. Structural pruning is best completed according to the needs of the individual species rather than as a universal fall task.
Young trees may need protection from rodents, deer, or sunscald. Remove stakes and ties that are no longer required so they do not constrict growth.
6. Winterize the Irrigation System
Water remaining in irrigation lines can freeze, expand, and damage pipes, valves, fittings, and sprinkler heads.
Shut down and winterize the system before sustained freezing temperatures arrive. The correct method depends on the system design. Backflow devices and other exposed components may also need protection.
Record any broken heads or coverage problems discovered during the season so repairs can be planned before spring startup.
7. Check Drainage and Downspouts
Clear catch basins, channel drains, and drainage outlets. Extend downspouts to suitable locations and confirm that water can move away from buildings.
Snowmelt follows the existing grade, so a low area that collects fall rain may become a larger problem in spring. Correcting minor drainage issues before winter can help protect lawns, garden beds, and hardscape bases.
8. Clean Patios and Walkways
Remove leaves, soil, food residue, and organic growth from hard surfaces. Clear debris from paver joints and drainage channels.
Inspect for sunken or loose sections that may create winter trip hazards. Water should not remain in low areas where it can freeze repeatedly.
A professionally planned outdoor construction project should account for drainage and freeze-thaw conditions from the beginning.
9. Inspect Retaining Walls
Look for leaning, bulging, separated caps, washed-out soil, or blocked drainage outlets. Some surface staining may be cosmetic, but visible movement deserves closer attention.
Do not block outlets that allow water to escape from behind the wall. Saturated soil creates additional pressure during winter and spring thaw.
10. Store and Protect Outdoor Items
Clean and store hoses, tools, cushions, lightweight furniture, and seasonal décor. Secure items that could move during wind or snow removal.
Follow manufacturer guidance for outdoor kitchens, water features, pumps, lighting, and fire features. Shut off and protect water lines where applicable.
11. Plan Snow Storage
Decide where snow will be placed before the first storm. Avoid repeatedly piling snow against fences, retaining walls, shrubs, or locations where meltwater will flow toward the home.
Mark delicate edging, lighting, irrigation components, and low structures so they remain visible to anyone clearing snow.
12. Document Ideas for Spring
Fall is an excellent time to photograph problem areas and record what did not work during the season. Note where more shade, privacy, seating, drainage, or planting would improve the property.
Starting a yard design during the off-season provides time to make informed decisions before spring demand increases.
Prepare Now for an Easier Spring
A winter-ready landscape is cleaner, safer, and better protected from seasonal stress. The most important tasks are those that preserve drainage, prevent frozen water damage, and protect the long-term health of plants and outdoor structures.

Frequently Asked Questions
When should irrigation be winterized in the Okanagan?
It should be completed before sustained freezing temperatures arrive. Timing varies with fall weather and the system’s exposure.
Should all perennials be cut down in fall?
No. Diseased material should be removed, but some healthy stems and seed heads can remain for winter interest and habitat.
Should I water plants before winter?
Plants, especially recent installations and evergreens, should enter winter adequately hydrated, but the soil should not remain saturated.
Can patio repairs be done in fall?
Yes, if weather and ground conditions allow proper excavation and compaction. Repairs should not be rushed once freezing conditions begin.
