Garden Soil

Soil Type

Water: Climbing hydrangea originates from woodlands and thrives in consistent moisture with moderate drought tolerance. Watering should occur every 1-2 weeks to mimic natural rainfall. This versatile plant adapts well both outdoors and indoors, with growth influenced by water availability, supporting optimal health and development.

Fertilize: For climbing hydrangea, use a balanced 10-10-10 NPK fertilizer at 2 cups per plant in spring before growth starts. Apply monthly during the growing season, reducing frequency in late summer. Always water thoroughly after fertilization to prevent root damage from salt accumulation.

Pruning: Pruning methods for hydrangeas vary based on their blooming types. Bigleaf and oakleaf hydrangeas require pruning in early summer, focusing on dead branches. 'Endless Summer' can be pruned year-round, while smooth and panicle hydrangeas bloom on new growth, allowing flexibility in pruning except during spring budding.

Propagation: Climbing hydrangea is best propagated through cuttings of healthy semi-woody stems, measuring 6-8 inches. Ensure cuttings have leaf nodes for root and leaf development. Use rooting hormone, plant in well-draining, moist soil, and provide indirect light and humidity. Rooting may take time.

Repotting: Climbing hydrangea requires pots with excellent drainage to thrive, ensuring proper moisture levels and preventing root rot.
