The plant tag on the hydrangea will tell you if the plant blooms on old wood, new wood or both. It is always best to wait and prune your hydrangeas in the spring. Once the plant starts growing you will see stems that do not have any leaves and are brittle when bent.
These stems should be pruned near the base of the plant since they are dead and will not produce any blooms. Weather is another factor….
Hydrangea buds are very sensitive to cold. So if you have an old wood hydrangea it is a good idea to wrap your hydrangea for the winter. Remember, old wood hydrangeas set blooms in the fall for the following spring. So if the buds produced in the fall are frozen in the winter, you will not have blossoms in the spring.

Quick facts. My best guess is that this plant is dead. That said, I would keep watering it and see if new shoots come up out of the ground. Never say never!
I work at a nursery and so many times have coworkers been piling up plants, including the beautiful hydrangea! I saw potential though. Ya know, the snap test or scratch test on the branches. Good thing I saved those puppies bc man did they grow back in spades.
Not once have I thrown out a plant whose roots were in decent shape. I like to snoop around down there too. And it always pays off. Hello, I have 2 hydrangeas that have blooms but it is really hot this week. They get shade after 3 but some of the leaves burned on one and the other has some yellow leaves and the leaves are more sparse. It has been a scorching 90 in full blazing sun.
Its more likely that the burning, yellowing, and sparseness is from the heat. Use a moisture meter or stick your finger in the soil and see if it feels like a well wrung-out sponge.
My hydrangeas were planted last year. I have green leaves but not a single flower. I have heard they skip a year of blooming sometimes.
Are you fertilizing? Flowers can be sparse on new plants until they become established, but an overabundance of nitrogen can also support the growth of foliage at the expense of blooms. But being from South Florida and moving to Western New York zone 5 , my partner cut back one of my hydrangeas that grow on old wood, and he did it at the wrong time.
Therefore I got nothing goin on with that hydrangea this season. In addition, hot as heck this summer w a drought to boot.
Question- you mention deer but what about rabbits eating them? Oh no! Maybe next year?! They usually go for other plants first. How do I test the soil I have complete hedge of Hydrangea and only get a few flowers now. I did feed Erricasious soil 2 years ago and not had many flowers since.
You can buy soil tests online and then you dig up a small section of soil as close to the base of the hedge as you can get. Some tests provide an immediate reading, while others need to be sent away to be analyzed. My preference, however, is to go through my local extension office. They can offer a bit of extra insight — since they know your climate best — and accuracy.
If you go this route, reach out to them, and … Read more ». I have a hydrangea that is about 4 years old. Could too little sun be the problem? What else is growing nearby? Do you know what variety you have? And how large was it when you planted it? The best time of day to plant is early morning or late afternoon.
The cooler parts of the day offer protection against heat stress. Keep new plants well-watered until established. Knowing where to plant hydrangea shrubs is an important first step. Many people plant hydrangeas in beds next to their homes or fences. This is because hydrangeas love the warm morning sun, but they dislike the heat of the afternoon. The best place to plant hydrangeas is in a sheltered location with sunny mornings and shady afternoons. You often find this on the north or south side of your home.
Avoid planting directly underneath trees, which can lead to competition for water and nutrients. High winds can rip and damage leaves and destroy the flowers.
Hydrangeas grow well in soil containing an abundance of organic material. Good drainage is vital. While hydrangeas like moist soil, they cannot tolerate being waterlogged. Soggy, poor draining soils can cause root rot. In just a few weeks, your hydrangeas can quickly die. If you have heavy soil, consider mixing in plenty of compost prior to planting to improve soil quality.
To plant hydrangeas, simply dig the planting holes 2 feet wider than the root ball. Keep the depth of the hole consistent with the size of the root ball so your plant sits level with or just higher than the surrounding soil. By creating a slight mound, you help increase water drainage away from the base of the plant.
One hydrangea can turn into many through simple propagation techniques. Bigleaf and panicle hydrangeas are best propagated through layering in early to mid-summer. All you have to do is:. Smooth and oakleaf hydrangeas put out new shoots through underground stems.
Just dig up the young plant and separate it away from the main plant. It can then be transplanted to a new location. These tips provide all you need to know about how to care for hydrangeas. The hydrangea blooming season depends upon the type and cultivar as well as your planting zone. Most new growth hydrangeas put on buds in early summer to bloom in the following spring, summer and early fall seasons.
In hot climates, hydrangeas may stop blooming in the heat of summer, but will rebloom in the fall. All that is required is the occasional removal of dead wood.
Deadheading hydrangeas will keep your plants blooming into fall.
