Do you know of a Houston hydrangea club? I’ve made two attempts to grow hydrangeas, both of which were spectacular failures.
A: I’m not aware of a hydrangea club in my area, but if you come across a garden with robust plants, take note of where they are planted and how much direct sunlight they receive.
In my Houston garden, I had to learn how to cultivate hydrangeas from scratch. I was eager to plant them here because I am from Georgia, where the lovely bushes don’t require much care and fill many gardens. I eventually discovered the ideal locations in my garden as well as the ideal cultivars for those locations.
It has been shown that morning sun and afternoon shade or filtered sun are preferable. In complete shade, hydrangeas bloom ineffectively or not at all.
Also crucial are well-draining soil and dirt that has been composted. Even in the summer, hydrangeas prefer damp soil; nevertheless, they cannot endure wet circumstances. In heavy, poorly draining soil, avoid planting.
Mulch should be applied in layers of three inches to help soil temperatures and moisture retention.
After May-June flowering, prune. Do not prune traditional mopheads, lacecaps, and oakleaves that set their buds on ancient wood in the late winter. Repeat bloomers that flower on new wood won’t be harmed.
Here, traditional bigleaf cultivars bloom in May and June with a range of flowers, from pink in more alkaline soils to blue in more acidic ones. In neutral soil, flowers can be either color.
‘Nikko Blue’ is a late-spring mophead that blooms. ‘Big Daddy’ blooms for a month or more and boasts 12-inch bloom clusters. The shrub known as “Blue Bird” is smaller.
‘Lady in Crimson’ is a beautiful lacecap with red stems and veins that is mildew-resistant. In my garden, it has flourished for many years. Another lacecap is called “Blue Dove.”
Newer bigleaf hydrangeas with repeat blooms extend the growing season into the fall. The Endless Summer Collection’s varietals and Remontant’s “All Summer Beauty” blossom on fresh wood. The mophead-like Endless Summer cultivar “The Original” blooms profusely in the spring and again in the months that follow. The flowers on “Twist-n-Shout” are blue and purple. In acidic soil, “Blushing Bride” ages from white to bluish pink or even blue. To promote more blossoms on the growth of the current year, remove spent blooms.
Have you ever tried the H. quercifolia, a remarkable shrub with foot-long, cone-shaped panicles of creamy white flowers and broad, lobed leaves endemic to the United States? The fragrant blossoms first turn a delicate rose color before aging to a purplish-brown color. Before the shrub loses its leaves for the winter, the foliage becomes reddish-purple in the fall.
Although it also looks well in formal gardens, this “woodsy hydrangea” is perfect for casual settings. Oakleaf varieties range in height from 4 to 7 feet and can withstand a little more sun.
In alkaline soil, mophead and lacecap hydrangea blossoms are pink; in more acidic soil, blue.
Sprinkle a cup of dolomitic lime around the bush, then water if you want pink blossoms.
Early in the fall, add 2 teaspoons of sulfur or aluminum sulfate around the hydrangea to encourage blue blossoms.
A 19-year-old azalea of mine occasionally blooms. I used to get a bush full of blossoms every year, but now I only get a few dozen. About four to five years ago, the issue first surfaced. Do these plants have a lifespan of 15 years?
A: Less blooming may be caused by inadequate sunlight, unhealthy soil, inappropriate trimming, or all three.
The optimal conditions for traditional spring-flowering azaleas to bloom are morning sun and midday shade in summer, or filtered sun all day. Species that bloom repeatedly require more sunshine.
Verify any tree limbs that may have been shading your plant more and more. You might be able to thin the branches above your shrub if they are casting too much shade on your azalea by doing so.
Although azaleas don’t have a fixed lifespan, elderly, worn-out shrubs may benefit from rejuvenation to regain energy and produce additional blooms. Although your plant has less blossoms, how does the shrub overall look? Is it healthy and bushy?
Improve the soil, drainage, and fertilization to promote a larger, healthier shrub that will produce more blooms. You should also prune heavily to assist the shrub regenerate and let light reach the center of the plant.
In order to produce a broader appearance, you might want to prune certain branches back to about a foot above the soil line rather than the usual third or so of the total size.
After the spring bloom, prune the lanky stalks back toward the center of the plant at various lengths.
This should promote both a broader appearance and a more organic shape for the shrub as a whole. Mulch, fertilize, and water.
After the initial flush of new growth, you can trim again if necessary in late spring.
If you prune in the summer after the buds have set, you risk losing the blooms for the following year.
Afterwards, fertilize. In late March, scatter 2-4 cups of alfalfa pellets about the shrub (or now in early April). After the pellets have broken down later in April, apply a balanced organic fertilizer.
Because azaleas have shallow roots, keep the soil moist. Spread mulch made of local materials or pine needles.
Can hydrangeas be grown in Houston, Texas?
It’s not difficult to grow hydrangea in Houston (South Texas), but it’s also not simple. It can be very difficult to grow a beautiful hydrangea shrub that will blossom and endure in the sun and humidity.
It gets difficult when you have to choose the right variety up front. The Oakleaf hydrangea is the kind that thrives in our climate (Hydrangea quercifolia). Although it performs better than other varieties, this lovely shrub does not resemble the hydrangeas we see in books or at flower shops. The cream-colored, cone-shaped flowers on this 8-foot-tall shrub have a rounded appearance. Throughout the season, flowers will transform to pink and even reddish brown in the autumn (note: you cannot change the color of Oakleaf hydrangea by changing acidity of the soil)
PeeGee hydrangea follows as the best performer for South Texas on our list of hydrangeas (Hydrangea paniculata). Again, not the hydrangea you see in magazines. Typically white-green, cone-shaped blossoms eventually turn pink with maturity. If unpruned, PeeGee hydrangea can reach a height of 15 feet, which is impressive for a shrub. PeeGee hydrangeas can often be taught to resemble trees with correct pruning.
However, the picture-perfect French hydrangea or mopheads are what the majority of us would like to grow (Hydrangea macrophylla). These hydrangeas are undoubtedly the most challenging to grow in Houston (and southeast Texas). Do you feel up to the task?
Starting with the ideal location for hydrangeas: The east side of the home (or any other structure) will receive morning sun and afternoon shade. If space on the east side is not a possibility, your other choice is the north side. Of course, if you’re like me and have trouble with orientation, pull out your compass or pour yourself a cup of tea, and spend some time watching: Find a location that receives some morning sun but is sheltered for the majority of the day.
The size of your site is the second thing to think about. Hydrangeas require space to expand. Take into account that French hydrangeas can reach heights of 7 feet and a width of 8 feet. For your hydrangea to flourish, leave at least 2 feet in each direction (from the plant’s center) when you plant it.
The hue of the hydrangea is the third factor to take into account. In Southeast Texas, pink and red colored blossoms are the easiest to grow (our clay soil is very alkaline and as such works best for pinks and reds). Once you master hydrangea cultivation, you can experiment with altering the soil’s acidity (If you want blue hydrangeas, you will need to add Aluminum sulfate to the soil, to lower your pH and make soil more acidic).
Got it all? Let’s make a large hole. The hole must be twice as wide as the pot that your hydrangea came in. The hole should be dug to a depth equal to the soil in your pot plus 4 inches. Fill the hole with compost to a depth of about 4 inches. Add the soil you dug out over your hydrangea before planting it. Mix potting soil in with your clay soil if it’s too dense (keep the ratio 3:13 part potting soil, 1 part clay). Mulch should be applied to the top 4-5 inches of the plant. We advise using cedar mulch (keeps the termites away). Water the mulch until it’s evenly wet.
Maintaining the health of your hydrangea comes last but not least. Moist soil is ideal for hydrangeas. Hydrangeas require daily watering until they are established (2-3 weeks). Just water the dirt (mulch) around the roots; don’t water the leaves or the flowers; let the rain take care of it. Early in the morning is advised for watering hydrangeas, followed by late at night. Once established, you must experiment and make a few observations. Water your hydrangea bush every other day as of now. Maintain that schedule if your leaves appear healthy (not drying out or wilting). You need to reduce the frequency of watering if your leaves begin to turn yellow to rust-colored. Mulch will quickly become your closest ally. It safeguards the roots, effectively holds water, and gives bugs a place to live.
When should your hydrangea be planted is the next concern. The best response for our area is: When the weather is nice outside. It shouldn’t be very hot, wet, or cold: between November and April (weather report should not mention any hard freeze). Only from February to May do we often sell hydrangea at Scent & Violet.
Would you like to raise the ante a bit? Place thyme, lemon balm, and chives close to your hydrangeas. These plants may thrive in the shadow and will aid in luring helpful insects. Why not utilize some of them in your cooking as well? Also think about growing some native Texas flowers that do well in shade.

Where should hydrangeas be planted for greatest results?
Plant hydrangeas close to a water source in an area with lots of light. Choose a location in the South where there is morning sun and afternoon shade. Hydrangeas can tolerate full-day sun in the north.
When do hydrangeas bloom?
The type, cultivar, planting zone, and hydrangea blooming season all affect when they bloom. The majority of hydrangeas with new growth form buds in the early summer in preparation for blooming the next spring, summer, and early fall. Hydrangeas may stop flowering in the heat of the summer in hot locations, but they will blossom again in the fall.
How do you cut back hydrangeas?
Hydrangea plants don’t require pruning if they are allowed plenty of room to develop in the garden. Only the periodic clearance of dead wood is necessary.
Do you need to deadhead hydrangeas?
Deadheading hydrangeas will keep your plants blooming into fall. Hydrangeas make wonderful cut flowers, so there’s no need to wait until the flower wilts. Leave the early fall blossoms alone so they can fade naturally. In the days leading up to your freeze date, you don’t want to promote new growth.
How do you control hydrangea color?
The distinction of hydrangeas is that you can modify their color. But keep in mind that not all hydrangea varieties can change their color. H. macrophylla, a species of bigleaf hydrangea, responds to changes in soil pH. Hydrangeas can absorb aluminum thanks to a low soil pH, which gives the blossoms a lovely blue hue. Reduce the pH of your soil by mixing in sulfur or peat moss to enhance the number of blue hydrangea flowers. Throughout the growth season, you can keep amending your soil with extra aluminum sulfate. When you add ground limestone to boost the pH, pink and red blooms shine.
You may precisely modify your hydrangea color using a soil pH test. To avoid the plant from being harmed, keep the pH level below 7.5. In the fall, all hydrangeas will naturally fade regardless of the modifications you’ve made. Don’t worry, the plant will display vibrant, new blossoms once more in the spring.
Can hydrangeas grow in shade?
Although they won’t blossom in complete shade, hydrangeas prefer dappled or infrequent shade. How much sun do hydrangeas need is more important to consider than whether they love the sun or the shade. Your hydrangeas require more sunlight the further north in your garden you are. A general guideline is six hours of sunlight each day. However, southern hydrangeas can thrive with just three hours of sunlight per day.
Can hydrangeas grow in full sun?
While hydrangeas prefer morning sun, they struggle in the hot, afternoon sun. For these gorgeous creatures, partial shade in the later hours of the day is optimal.
Can you grow hydrangeas in pots?
Even if you don’t have enough room in your garden to cultivate hydrangeas, you can still enjoy these lovely blossoms by learning how to grow hydrangea in a pot. As long as you follow the fundamentals of caring for hydrangeas, the procedure is rather straightforward. Select a pot with at least an 18-inch diameter to accommodate the mature size of the particular hydrangea you are growing. In order to maintain the constant moisture level that hydrangeas demand, look for non-porous containers. Excess water will be able to adequately drain thanks to drainage holes. Consider growing dwarf hydrangeas like Buttons ‘n Bows, Mini Penny, and Little Lime.
How do you keep hydrangeas from wilting?
Morning irrigation on a regular basis can assist stop withering. Some hydrangea cultivars simply can’t stand the heat. No matter how much water you give them, they will begin to wilt in the afternoon heat. Mulch applied in layers can help soil retain moisture and stay cool. You shouldn’t be concerned if your hydrangeas bloom again once the day cools. A little midday wilting is preferable to overwatering and drowning your hydrangeas.
Are hydrangeas able to thrive in Texas?
Hydrangea shrubs come in a wide variety of shapes, sizes, and cultivars that come in an amazing array of colors. While some hydrangea varieties won’t do well in the stifling Texas heat, there are undoubtedly those that do well there.
The most common kind of hydrangea in our area is unquestionably the oakleaf variety since it can withstand the heat without becoming overheated. They don’t exactly resemble the common hydrangeas with bloom clusters in the shape of globes that frequently adorn the covers of home and garden publications. Oakleaf hydrangeas have tiny white blooms that grow in panicles that resemble cones and tumble downhill, giving them a hybrid appearance between hydrangeas and lilacs. As you may undoubtedly infer from the name, its lobed leaves resemble oak tree leaves quite a little. Before the plant goes dormant for the winter, the blossoms change as they ripen from milky white to delicate pink and occasionally take on a wine-red hue. Oakleaf hydrangeas can grow up to 7 feet tall when fully grown.
Another magnificent species of hydrangea that thrives in Texas is PeeGee. With huge, cloud-like bunches of blooms reaching heights of up to 15 feet, they are absolute attention-getters. These shrubs are excellent accent plants for the front yard because you can even train them to grow into trees. PeeGees have blooms that start out white with a delicate green tint and gradually grow more pink as they mature, much like oakleaf hydrangeas do.
The traditional variety of French hydrangeas that you frequently find in bridal bouquets. Their mophead-shaped, spherical blossoms appear in a stunning array of white, green, purple, pink, and blue hues. By experimenting with the pH and Aluminum levels in the soil with different amendments, you can even extract a Sleeping Beauty and turn them from pink to blue, or from blue to pink. Although these hydrangeas are extremely popular in more Northern parts of the US, they are obviously more difficult to maintain in Houston, but it is possible with the right care. You may create the garden of your dreams if you take extra care to ensure that the striking, icy blue blossoms receive all they require to thrive.
