What does it take to make a climbing hydrangea flower? Ours was planted 3 years ago and is growing energetically. It’s in a protected nook near the patio and gets very little direct sunlight, but doesn’t act sun starved. We gave it a shot of slow release fertilizer on planting, and once since. Somewhat inadvertently it gets plenty of water, since the hose spigot is nearby and leaks, but drainage does not seem to be the problem. It now fully occupies an 8-foot trellis but shows no interest in flowering. Is it youth, lack of sun, too much or too little fertilizer, bugs, lack of pruning or what? When do these plants bloom and what conditions do they like?
Climbing hydrangea (Hydrangea anomala subsp. petiolaris) is a choice vine with rich, vigorous, dark green foliage, growing ultimately to 20 feet high and 10 feet wide. The extra moisture it gets is good, and it can bloom in shade. Brent Horvath, president and grower at Intrinsic Gardens, Hebron, has seen it blooming beautifully under a canopy of trees.
After weighing all the cultural factors you described, Horvath has concluded that your vine may be immature and will need a couple more years before it flowers. Climbing hydrangea matures very slowly, especially when it’s sold in 2 gallon containers.
Can I purchase multiple issues of the magazine?
I brought a frangipani (Plumeria) back from Hawaii last April when it was just a leafless branch. It sprouted leaves and grew over summer. Now it is losing its leaves. How can I keep it growing over winter? Will it bloom?
What is the best way to dig up, clean and store gladiolus and dahlias? What are the little white sacs on glad bulbs?
