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.
Will a trumpet vine growing on a tree harm it?
Trumpet vine (Campsis radicans) is a vigorous vine which can climb to the top of a tree in one season and spreads by suckering roots. It blooms in full sun in clusters of 3-inch-long orange tubes with flaring scarlet lobes.
The vine will not harm an established tree but a young tree could be stressed.
“There may be root competition between the vine and the tree for moisture, especially if your tree needs a lot of water. However, trumpet vines can grow with less moisture. When customers claim their vine does not bloom, it is because they are watering and pampering it too much,” says Lori Harms, greenhouse manager, Countryside Nursery and Garden Center, Crystal Lake.
I have read that purple coneflowers (Echinacea) are a good source of food for birds in the winter. Will they be okay if not trimmed back until spring? If so, how early should they be trimmed?
Do the ants on my peony flowers help buds to open, or is this an old wives’ tale? What are the extremely tiny, microscopic yellow wormy looking bugs crawling on my pink peony flowers? My peonies are beautiful, but I don’t want all these bugs.
