🌿 Growing Note
• Sunlight: Position in a location where the upper vines receive at least 6 hours of direct sunlight, while keeping the root zone shaded and cool with mulch or companion plantings.
• Soil: Thrives in fertile, humus-rich, moist, and exceptionally well-draining soil with a neutral to slightly alkaline pH.
• Watering: Water deeply during dry spells, ensuring the soil remains evenly moist without becoming soggy or waterlogged.
• Fertilizing: Feed with a balanced, slow-release fertilizer or organic compost in early spring to support vigorous growth and heavy blooming.
• Pruning: Follow Group II pruning guidelines in early spring—simply clean out dead or damaged stems and cut back the remaining healthy framework to strong leaf nodes.
