What’s wrong with my climbing hydrangea?
Why is my climbing hydrangea not blooming? This is often due to pruning at the wrong time, too much shade or the plant still being immature. Prune only after flowering and give your plant time to establish. The best time to trim back climbing Hydrangea is after flowering in late summer. Because the plant produces flowers on the previous year’s wood, pruning earlier in the year sacrifices that year’s flowers. If you inherit an overgrown Climbing hydrangea, it is best not to hard prune it.As Paul explains, the ideal time to trim a hydrangea largely depends on its type, although autumn is never the right time to prune these ostentatious blooms. This is because most hydrangeas already have new flower buds on their stems. By cutting them back now, you would remove the buds and spoil next season’s blooms.In winter, climbing hydrangeas lose their leaves, revealing their woody stems and branching structure. The bare vines can add visual interest to the landscape, and the peeling, exfoliating bark provides texture against the winter backdrop.Because it takes time to establish, during which period the shrub is putting down roots, it can take a little while to flowering between 3-5 years. It is easy to grow because it needs little or no attention. Climbing hydrangea is self clinging with aerial roots.The best time to prune oakleaf hydrangeas (hydrangea quercifolia) is in summer—around June to July—right after the flowers finish blooming. If you prune in the fall, you’ll significantly impact next year’s growth by accidentally removing many new buds,” Berendsen says.
How to take care of a climbing hydrangea?
Grow Hydrangea petiolaris in moist but well-drained soil in shade or partial shade. Train the shoots initially onto galvanised wires or trellis along a wall or sturdy fence – after a season of growth they’ll form self-clinging aerial roots. Do not allow the soil to dry out, especially in hot weather. Hydrangeas need nutrients to bloom, but just any fertilizer won’t do. Make sure you’re using a using a bloom boosting, slow-release, granular fertilizer and follow the directions on the packaging for how much to apply. Apply fertilizer in early spring and again in July to help promote the rebloom.Fertilizer. Little fertilizer is needed. Climbing hydrangeas are naturally slow to establish, and fertilizing is unlikely to help. If you wish, a yearly application in early spring should be more than sufficient for its needs.Hydrangeas are long-lived shrubs, sometimes living for up to 50 years if properly cared for. They enjoy morning sun but afternoon shade, and they need frequent watering during the growing season.The best time to plant hydrangeas is early fall or spring, depending on your region. In areas with mild winters, planting in September or October allows the roots to establish before winter dormancy. In colder climates, it’s better to plant in early to mid-spring (April or May) after the risk of frost has passed.Avoid feeding hydrangeas after August, especially in regions with cold winters.
