Colorado Blue Spruce Fall Planting Care in Ontario: Watering, Staking, and Winter Prep

Fall Watering Schedule

• Weekly 1-inch deep watering until ground freezes.
• Roots grow until soil temp <40°F.
• During winter thaws: water if soil dry 4–8″ down.

Staking for Winter Winds

1. Two stakes, driven into planting hole edges (not through root ball).
2. Broad straps (not wire) – allow 2″ trunk movement.
3. Remove stakes by next fall – prolonged staking weakens trunk.

Mulch & Winter Protection

• 3–4″ mulch (bark, straw) after ground freezes – prevents frost heave.
• Burlap screen (not wrap) on windward side if exposed – reduces desiccation.
• Anti-desiccant spray (Wilt-Pruf) late fall – optional but helpful for new transplants.

Spring Transition

Remove burlap screen early spring. Resume weekly watering. Fertilize lightly at bud break.
