Planting Moss Roses in Extreme Climates: Fall Planting, Deep Grafting, and Mulching for Success

Fall Planting (Best for Washington State)

Roots grow all fall and early spring, building a network to support summer top growth. Spring planting delays flowering because roots must establish first.

Moss Rose Special Needs

• Prone to mildew if roots overheat.
• Plant graft well below soil level.
• Apply 6-inch mulch (any local material) to keep roots cool/damp.
• Water daily during 100°F spells.
