My climbing hydrangea (Hydrangea anomala subsp. petiolaris) is a beautiful plant that I have been growing for several years. It has large, green leaves and long, woody stems that are covered in small white flowers in the summer. I have always loved this plant, but I was disappointed last year when it did not bloom.
I was even more disappointed this year when it still has not bloomed. I have done some research and found out that there are a few reasons why my climbing hydrangea might not be blooming.
If you have a climbing hydrangea that isn’t blooming, there are a few things that could be the culprit. First, check to see if the plant is getting enough sun. Climbing hydrangeas need at least six hours of sunlight each day in order to bloom properly.
If your plant is in too much shade, it may not bloom at all. Another reason for lack of blooms could be too much fertilizer. Fertilizing climbing hydrangeas once a year is plenty – any more than that can actually prevent blooming.
Finally, make sure you’re pruning correctly. Climbing hydrangeas should be pruned after they bloom in the summertime. If you prune them too early or too late, it can affect their ability to bloom the following season.
Planting Climbing Hydrangeas – Fragrant Flowering Vine
Why are There No Flowers on My Climbing Hydrangea?
If you have a climbing hydrangea (Hydrangea anomala subsp. petiolaris) and it’s not flowering, don’t despair! There are several possible reasons why your plant may not be blooming.
One reason could be that the plant is too young.
Climbing hydrangeas take a few years to reach maturity and start producing flowers. So if you’ve only had your plant for a year or two, give it some time – it should start blooming eventually.
Another possibility is that the climber isn’t getting enough sunlight.
Hydrangeas need at least six hours of sun per day in order to bloom well. If your plant is in too much shade, it may not produce many flowers.
It’s also possible that the soil around your climbing hydrangea is too rich in nitrogen.
An overabundance of nitrogen can actually prevent plants from flowering, so if you’ve been fertilizing regularly, try cutting back on the amount of fertilizer you’re using or switching to a phosphorus-rich fertilizer instead.
How Do I Get More Flowers on My Climbing Hydrangea?
If you want more flowers on your climbing hydrangea, there are a few things you can do. First, make sure it is getting enough sun. It should get at least six hours of direct sunlight each day.
Second, fertilize it regularly with an all-purpose fertilizer. Third, water it deeply and regularly during the growing season. Fourth, prune it after it blooms to encourage new growth and more flowers.
What Do You Do If Your Hydrangea Doesn’T Bloom?
If you’re wondering why your hydrangea isn’t blooming, there are a few possible reasons. Here are a few things to check if your hydrangea isn’t blooming:
1. Check the soil pH – Hydrangeas prefer slightly acidic soils with a pH of 5.5 to 6.5.
If the soil is too alkaline, it can prevent the plant from absorbing essential nutrients that it needs for flowering. You can test the soil pH with a simple soil test kit (available at any garden center).
2. Make sure the plant is getting enough sun – Hydrangeas need at least 4 hours of direct sunlight each day in order to bloom properly.
If the plant is in too much shade, it won’t produce as many flowers.
3. Ensure that the plant is getting enough water – Hydrangeas require consistently moist soils in order to bloom well. During hot summer months, they may need to be watered every day or even twice a day in order to keep the soils moist but not soggy.
If the plant is drought-stressed, it will likely produce fewer flowers (or none at all).
4. Fertilize regularly – Like all plants, hydrangeas need nutrients in order to grow and bloom well. Use a fertilizer formulated for acid-loving plants (such as those containing sulfur) and apply according to package directions during the growing season (spring through fall).
If you’ve checked all of these things and your hydrangea still isn’t blooming, it’s possible that it’s not getting enough of one or more of these critical factors for flower production (sunlight, water, nutrients).
Does Climbing Hydrangea Bloom on Old Wood?
Yes, climbing hydrangea blooms on old wood. This means that if you prune your plant in the early spring, you will be removing potential flowers for that season. However, many gardeners still prune their climbing hydrangeas anyway because it helps to keep the plant tidy and under control.

Climbing Hydrangea Problems
Climbing hydrangeas are a popular choice for homeowners looking to add some greenery to their home’s exterior. These vining plants are known for their large, showy flowers and their ability to grow quickly. While climbing hydrangeas are generally low-maintenance, there are a few problems that can occur.
Here’s what you need to know about common climbing hydrangea problems and how to solve them.
One of the most common problems with climbing hydrangeas is powdery mildew. This fungal disease affects the leaves of the plant, causing them to develop a white or gray powdery coating.
Powdery mildew is more likely to occur in humid conditions or when the leaves are wet for extended periods of time. To prevent powdery mildew, water your climbing hydrangea early in the day so that the leaves have time to dry before nightfall. You can also apply a fungicide specifically designed for powdery mildew if the problem persists.
Another problem that can affect climbing hydrangeas is leaf spot. This fungal disease causes small brown or black spots to form on the leaves of the plant. Leaf spot is often caused by overwatering or poor drainage, so be sure not to water your climbing hydrant too frequently.
If you notice leaf spot, remove any affected leaves from the plant and dispose of them properly (do not compost). You can also apply a fungicide designed for leaf spot if necessary.
If your climbing hydrangea isn’t blooming, it could be because it’s not getting enough sunlight.
These plants need at least six hours of sunlight per day in order to produce flowers. So if your climber is planted in an area that doesn’t get much sun, consider moving it to a sunnier location. Another reason why your climber might not be blooming could be because it’s too young – typically, these plants don’t start producing flowers until they’re 3-5 years old.
Patience is key!
Finally, aphids can sometimes be a problem for climbing hydrangeas. These tiny insects feed on plant sap and can cause damage to both foliage and stems. Aphids are most active in spring and summer months, so keep an eye out for them during those times of year.
Climbing Hydrangea Bloom Time
If you’re looking for a climbing plant that will give your garden an extra pop of color, look no further than the climbing hydrangea! This beautiful vine is known for its large, showy flowers that bloom in a variety of colors including white, pink, and purple. The best time to plant climbing hydrangeas is in the spring or fall, and they typically bloom from late spring to early summer.
Keep reading to learn more about how to care for your climbing hydrangea and when you can expect it to bloom.
When it comes to planting location, climbing hydrangeas prefer partial sun to full shade and moist, well-drained soil. If you live in an area with hot summers, choose a spot that gets some afternoon shade to protect the plant from wilting in the heat.
When planting, be sure to dig a hole that’s twice as wide as the root ball but not much deeper. Backfill the hole with amended soil and water deeply until the ground is saturated. Once planted, apply a layer of mulch around the base of the plant (but not up against the stem) to help retain moisture and suppress weeds.
Climbing hydrangeas are relatively low-maintenance vines once they’re established, but they do require regular watering during their first growing season until they become drought-tolerant later on. Be sure to keep an eye on the soil moisture level and water whenever it starts to feel dry several inches below the surface. In terms of fertilizer, yearly applications of compost or slow-release granular fertilizer in early spring should be sufficient.
Pruning is only necessary if you want to control the size or shape of your climber – otherwise just let it grow!
As mentioned earlier, climbing hydrangeas typically bloom from late spring into early summer. The exact timing will depend on your particular climate/region as well as which cultivar you’ve planted (earlier blooming varieties are available).
How to Train a Climbing Hydrangea
One of the best ways to train a climbing hydrangea is by using an espalier. This will give the plant support while it grows, and also allow you to control its shape. To create an espalier, start by installing two posts in the ground at least 4 feet apart.
Then, attach horizontal wires between the posts at different heights. You can use plastic or metal ties to secure the wires to the posts.
Next, choose which side of the espalier you want your climbing hydrangea to grow on.
Then, plant your hydrangea at the base of the espalier on that side. Be sure to water it well after planting. As your hydrangea grows, train it to climb up the wires by gently tying it to them with soft ties or strips of cloth.
You can prune your climbing hydrangea as needed to keep it under control and encourage new growth. However, avoid pruning it too heavily, as this can damage the plant. With a little care and attention, you can easily train a climbing hydrantea to grow beautifully on an espalier!
