Starting a Container Rose Garden in Boise, Idaho

Essentials for roses in pots:

• Containers ≥18" deep with drainage holes.
• Commercial potting mix or custom fast-draining blend—avoid garden soil.
• Daily watering in heat for small pots.
• Slow-release + liquid fertilizers as needed.
• Winter: store in protected spot (under trees, patio) where dormant but shielded from wind. Below -15°C? Bury pots or move to shed/greenhouse.
• Spring: replace top 3" of soil with compost/manure mix; add rose food.
• Don't overfeed—Osmocote 14-14-14 lasts all summer.

Buy locally for zone-appropriate varieties, or mail-order from Rogue Valley Roses (Oregon).
