Idaho Landscape Maintenance Guides
North Idaho has its own rules — spring arrives late, summers bake, and hard freezes can hit by early October. These guides reflect 20 years of working this specific climate, not generic national advice. Select any task below for step-by-step detail.
March – April
Spring Cleanup
- Dethatch and rake winter debris from all turf areas Deep Dive
- Inspect and clear weep holes in retaining walls Deep Dive
- Restart and test irrigation zones — look for winter pipe damage Deep Dive
- Apply pre-emergent herbicide before soil temps reach 55°F Deep Dive
- Prune dead wood from ornamental shrubs before new growth Deep Dive
- Edge all bed borders and refresh mulch (2–3 inch depth) Deep Dive
- Overseed thin turf areas with Idaho-appropriate cool-season blend Deep Dive
May – June
Growing Season Setup
- Fertilize turf with slow-release nitrogen formula Deep Dive
- Set irrigation to 1 inch per week — adjust for rain Deep Dive
- Stake new trees and monitor for wind rock Deep Dive
- Watch for aphids and spider mites on ornamentals Deep Dive
- Mow at 3–3.5 inches to shade out weed seeds Deep Dive
- Check drip emitters on shrub beds for clogs Deep Dive
July – August
Peak Summer Care
- Deep water trees bi-weekly — avoid shallow frequent cycles Deep Dive
- Watch turf for dry patches indicating irrigation head failure Deep Dive
- Aerate compacted high-traffic areas mid-August Deep Dive
- Deadhead perennials to extend bloom period Deep Dive
- Keep mower blades sharp — dull blades tear and brown turf tips Deep Dive
- Inspect hardscape for heaved pavers or shifting base course Deep Dive
September – October
Fall Transition
- Overseed bare patches before soil temps drop below 50°F Deep Dive
- Apply fall fertilizer high in potassium to strengthen roots Deep Dive
- Cut back ornamental grasses after frost — leave 4–6 inch stubs Deep Dive
- Blow out and winterize irrigation before first hard freeze (Oct 1 target for North Idaho) Deep Dive
- Plant spring bulbs before ground freezes Deep Dive
- Install anti-desiccant spray on broadleaf evergreens Deep Dive
November – February
Winter & Dormancy
- Apply de-icer (avoid rock salt near turf or plantings — use potassium chloride) Deep Dive
- Keep snowblower and shovels clear of drain paths Deep Dive
- Check mulch depth on tender perennials — add if below 3 inches Deep Dive
- Inspect retaining walls after freeze-thaw cycles Deep Dive
- Prune dormant trees — avoid pruning late February when buds swell Deep Dive
