Hydrangeas
What can I do to make my hydrangea tree bloom?
Smooth hydrangeas (Hydrangea arborescens), which get their name from the texture of their huge leaves, are more well-known for their massive, spherical, white flower heads. The most popular type, “Annabelle” (also known as Snowball Bush), was identified as coming from Anna, Illinois, by a horticultural expert in the 1960s. The ‘Annabelle’ hydrangea displays large, pure-white blooms that gradually turn green. A more recent cultivar, Invincibelle Spirit, blooms pink rather than the usual white. The smooth hydrangea, which is native to parts of North America, starts blooming in late June and keeps periodically flowering all summer long. In zones 4 through 9, it thrives in sunny or slightly shaded environments.
How to Get More Smooth Hydrangea Flowers:
- If the soil is damp, grow smooth hydrangeas in full sunlight. (Spots that occasionally dry out benefit from partial shade.)
- In droughts, especially in the sweltering summer, water them.
- soil amendment using organic matter (such as compost).
- In the early spring, soon as new growth begins to appear, trim back stems.
Many customers ask why their hydrangeas aren’t blooming. The primary reasons hydrangeas don’t bloom are incorrect pruning, bud damage due to winter and/or early spring weather, location and too much fertilizer.
There are hydrangea kinds that bloom on either fresh or old wood, or even both. Both new and old wood are the growth of the following year (spring), respectively.
- Consider that this year, you bought a Nikko Blue Hydrangea. For the next year, Nikko’s produce blooms in the fall. Your Nikko is therefore creating blooms this fall that will blossom in the spring.
- Therefore, you wouldn’t want to completely prune your Nikko Blue Hydrangea this fall while you are pruning your perennials. Pruning the Nikko Blue Hydrangea this fall would effectively mean cutting off your hydrangea flowers for the upcoming spring.
- The idea behind Endless Summer, a hydrangea variety that blooms on both old and new wood, is that the plant will set blooms this fall to blossom not only in the spring of the following year, but will also keep producing blooms in the spring of the following year to extend the blossoms into the summer.
- Once more, pruning your Endless Summer hydrangea in the fall would mean removing some of the flowers that would blossom in the spring.
The hydrangea’s plant tag will indicate whether it blooms on fresh wood, old wood, or both. It is typically preferable to wait until spring to prune your hydrangeas. As the plant grows, you’ll see stems that are fragile when bent and lack any leaves. Since these stems are dead and won’t produce any flowers, they should be clipped close to the plant’s base.
The second reason why your hydrangeas aren’t blooming is probably the weather. Buds of hydrangeas are extremely susceptible to cold. Therefore, it is a good idea to wrap your hydrangea for the winter if it is an old wood hydrangea. Keep in mind that old wood hydrangeas establish their blooms for the following spring in the fall. Therefore, you won’t have blossoms in the spring if the fall-produced buds are frozen in the winter.
You can wrap anything with regular burlap. Burlap should be wrapped around the plant and filled with mulch or leaves after the first hard frost and after the hydrangea’s leaves have dropped. In order for the buds to survive the winter and sprout the following spring, the plant receives insulation from this. Never wrap your hydrangeas in plastic. When warmer winter days arrive, the plant cannot breathe since plastic, unlike burlap, doesn’t breathe. As a result, the plant can heated to such high temperatures that it cooks within the plastic and perishes.
The second most frequent weather-related cause hydrangeas do not blossom is late spring killing frosts. We saw really chilly temperatures in April both this year and last year after beautiful spring days. When springtime temperatures drop below freezing, hydrangeas need to be covered with an old beach towel or sheet. Because of the temperature dip, there won’t be any blossoms.
The majority of hydrangeas require at least 3 to 4 hours of light per day to bloom. The best light is in the early morning, midday light is acceptable if it is dabbled light rather than beating sun, and afternoon sun is typically too hot. Check the plant label, though. Newer hydrangea cultivars are being created that can withstand more sun exposure time and sun intensity. A hydrangea in full sun will require much more watering than one in diffused light, so keep that in mind.
High nitrogen fertilizer should not be used to feed hydrangeas. Nitrogen is indicated by the first number on the fertilizer ratio. (The ratio stands for N, P, and K) For healthy leaves and general good growth, some nitrogen (N) is required; however, a ratio of 8-16-6 or any similar combination with a higher middle or phosphorus (P) value is preferred. The growth of roots and shoots is encouraged by phosphorus, which improves the blooming process.
Potash (K), the third element’s last quantity and the lowest ratio, is for plant hardiness. Because hydrangeas prefer acidic soil, they can be fertilized with fertilizers designed for such plants. Hydrangeas only require fertilizing twice a year, once in early spring and once in mid-summer. To avoid root burn, make sure the soil is always moist before applying a fertilizer.

In warmer areas, hydrangeas typically thrive in partial shade. pH of the soil has little effect on the color of this cultivar. In the summer and the first year after planting, keep the soil wet but not waterlogged. A hydrangea will thrive throughout its life with a weekly deep watering in hot weather. For hydrangeas, mulching at a depth of roughly 2 inches is strongly advised. Mulching will reduce your plant’s requirement for watering and protect it from harsh weather.

What distinguishes a hydrangea bush from a hydrangea tree?
Hydrangeas in bloom are a surefire indicator of summer. Nothing compares to the stunning sight of hydrangeas in bloom in a range of colors. Every summer garden looks beautiful with the white, blue, pink, or purple blooms coupled with the vibrant green foliage.
How wonderful would it be to see hydrangeas on trees instead of the usual low-growing hydrangea bushes? The good news is that you can. How to grow a hydrangea tree is described here.
Instead of large spherical blossoms, the Grandiflora variety of Hydrangea paniculata develops white conical flowers. It has the potential to reach a height of 25 feet with moderate pruning and good maintenance! Your greatest option for cultivating a hydrangea tree is Grandiflora, also referred to as Pee Gee Hydrangea by gardeners.
Prepare yourself for success before you plant. The USDA plant hardiness zones 5 through 8a are ideal for hydrangea tree growth, so check your zone. Make careful to pick a location with consistent bright light because hydrangeas enjoy full sun for the majority of the day and a little afternoon shade.
Typically, hydrangeas prefer rich, permeable, moist soil. To promote healthy growth, aerate the soil with Espoma’s All-Purpose Garden Soil and apply Espoma’s Bio-tone Starter Plus. If you’re planting numerous trees, make sure to thoroughly water them and give each hydrangea a minimum distance of 3 to 10 feet.
Pruning is one of the most crucial aspects of hydrangea tree growth. The training, pruning, and correct maintenance are what distinguish a hydrangea shrub from a tree. Springtime is the best time to prune. Remove old twigs that failed to develop wholesome growths and suckers from the tree’s trunk. Trim branches so they have two or three nodes each to keep your tree looking tidy (small bumps on the branch that signify growth).
Although it requires a lot of sunlight, your hydrangea tree will offer some shade on particularly sweltering summer days. Keep the soil moist to prevent drooping leaves and blossoms because greater sunlight requires more water. Before the height of the growing season in the spring, prune your hydrangea tree.
Growing a hydrangea tree sounds like the next step for you if you love your hydrangeas and want to see more than a standard shrub!
When hydrangeas don’t bloom, what should you do?
You may have overpruned your hydrangea the year before if it won’t bloom this year. Hydrangeas that aren’t blooming have frequently had their branches cut in the early summer and late winter. They will tend to die back more quickly than usual if they are overpruned, and you will have to wait a full year for them to bloom once more.
The solution is to only prune your hydrangea in the early spring when the dead wood is visible. Once more, if you notice your hydrangea isn’t blooming, double-check the kind and keep track of when it died the previous year. Keep in mind that it might require the old wood for it to blossom.
Finally, you might want to have your soil tested if your hydrangeas are not blooming and you’ve decided that nothing in this article pertains at this time. Your hydrangea may have luxuriant green foliage but no blossoms if your soil is nitrogen-rich. Like many other flowering plants, hydrangeas require phosphorus to effectively bloom and flourish. A fantastic technique to boost the phosphorus in the soil is by adding bone meal. Additionally, bear this in mind as you select a fertilizer for your plants.
What should I feed hydrangeas to encourage blooming?
When purchasing fertilizer, check the labels to see how much nitrogen (N), phosphate (P), and potassium are present (K). A general-purpose, balanced fertilizer such a 10-10-10 N-P-K or 12-4-8 N-P-K is typically best for hydrangeas. Consider using a fertilizer with additional phosphorus if you want your hydrangea blossoms to be bigger and more numerous.
Since phosphorus is the middle element, fertilizer with the formula 10-20-10 will do. Choose a slow-release granular fertilizer with the designation “bloom boost” if you’re looking into it because it might also include more phosphorus.
What occurs if hydrangeas are not pruned?
If and when you prune is the key to happy, healthy hydrangea flowers. Of course, fertilizing and offering the ideal environment have a lot to recommend them. However, if you don’t prune properly, your efforts will be in vain. Deadheading is not the same as trimming. Pruning refers to more drastic cutting to preserve shape or remove dead growth. However, feel free to discard spent blossoms or cut fresh ones to use in arrangements.
Hydrangeas can bloom on either fresh wood or old wood, depending on the species. The wood from which they blossom determines whether and when to prune.
Old wood-blooming hydrangeas do not require pruning and benefit from it. They’ll blossom more abundantly the next season if you leave them alone. But feel free to deadhead or gently thin. Just keep in mind that while new growth may appear, it won’t bloom until the following season. In our region, four different species blossom on aged wood. Additionally, they are not limited to the hues displayed here.
Climb using suckers. On your wall or trellis, resist the desire to remove the dormant growth.
The flower heads are more conical in appearance, and the leaves are large and resemble oak leaves. It’s a pleasant surprise for a hydrangea when its leaves turn reddish-orange in the fall.
They are very comparable to lacecap types, but smaller and with more compact leaves.
Pruning should be done in late winter or early spring on hydrangeas that bloom on new wood. Trim back to two feet to prune to shape. The next season’s blossoms are produced by strong, fresh growth that is encouraged by trimming. In our region, there are two types that bloom on fresh wood. They are also not restricted to the colors displayed.
Oakleaf variants are not included in cone-shaped blooms. Keep the blooms on throughout the winter to provide interest; even dried out, they are quite lovely.
regarded as a wild kind. They often have smaller blooms and leaves than Bigleaf variants and are completely white. They enjoy full sun and can grow very tall.
Knowing whether or when to prune now will help you avoid the disappointment of a hydrangea that doesn’t blossom. Don’t forget that a robust shrub will produce more gorgeous blossoms if it has well-draining soil and good organic fertilizer. Come on in, and we’ll show you where to go to develop your green thumb.
