I’ve prepared a raised bed in my yard that is the ideal size for one hydrangea to grow large and gorgeous (am sun, pm shade). So far, all I’ve seen at nurseries in the area are endless summer nikko blue and pink mopheads (Cornelius, Hou Garden Centers). Do you all know of any nearby nurseries with a larger variety of hydrangeas, particularly any of the more recent mophead varieties? I don’t know a lot about nurseries outside the loop. If not, I’ll probably simply choose a nikko, but I thought I’d ask. Thanks!
Are hydrangeas able to thrive in Houston?
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 colour 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 centre) when you plant it.
The hue of the hydrangea is the third factor to take into account. In Southeast Texas, pink and red coloured 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 sulphate 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 utilise some of them in your cooking as well? Also think about growing some native Texas flowers that do well in shade.
Your hydrangea lived and flourished, right? You want to prune it since it has gotten too huge. Check out this video from North Coast Gardening to learn how to prune hydrangeas properly.

When should hydrangeas be planted?
Learning the fundamentals of how to plant hydrangeas can help you save time and money, just like with most other items in your garden. You’ll improve your chances of enjoying big, vibrant hydrangea flowers for years to come by picking the appropriate site, getting the soil just right, and planting correctly.
When should I plant hydrangeas?
The best time to grow hydrangeas is in the fall, followed by early spring. The goal is to provide the shrub lots of time to develop a strong root system before it blooms. Early in the day or late in the day are the ideal times to plant. The day’s cooler hours provide relief from heat exhaustion. Water new plants frequently until they get established.
Locations to plant hydrangeas
The first step is knowing where to grow hydrangea plants. Hydrangeas are frequently grown in beds adjacent to houses or fences. This is so because hydrangeas prefer the mild early sun to the hot afternoon sun. A protected area with sunny mornings and shaded afternoons is the ideal spot to plant hydrangeas. This is frequently found on the north or south side of a house. Avoid planting underneath trees since it could cause competition for nutrients and water. Flowers and leaves can both be destroyed by strong winds.
hydrangea-friendly soil
The soil needs to be rich in organic matter for hydrangeas to thrive. Drainage is important. Although hydrangeas prefer damp soil, they cannot stand standing water. Root rot can be brought on by wet, poorly draining soils. Your hydrangeas could pass away in a matter of weeks. Consider adding a lot of compost to your heavy soil before planting to increase the soil’s quality.
Methods for planting hydrangeas
Simply dig planting holes that are 2 feet wider than the root ball for planting hydrangeas. So that your plant lies level with or just higher than the surrounding soil, match the depth of the hole to the size of the root ball. You can improve water drainage away from the plant’s base by making a small mound.
The best way to grow hydrangeas
Simple propagation methods can multiply a single hydrangea into several more. The optimal time to layer bigleaf and panicle hydrangeas is in the early to mid-summer. You only need to:
- Close to your hydrangea plant, make a tiny trench.
- Bend a branch such that the middle of the branch meets the earth in the trench (six to 12 inches of branch should extend past the trench).
- Where the branch meets the trench soil, make scuff marks on the bark.
- After the trench is filled, cover it with a paver, brick, or stone.
- The branch can be transplanted to a different area once it has established its own root system over time.
Hydrangeas with smooth or oakleaf leaves produce new growth from underground stems. Simply separate the baby plant from the main plant by digging it up. After then, it can be moved to a new spot.
Can you grow hydrangeas in Texas?
Hydrangea shrubs come in a wide variety of shapes, sizes, and cultivars that come in an amazing array of colours. 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.
Where to plant hydrangeas:
- A location with morning sun and afternoon shade is ideal. They’ll take more sun if you reside further north (possibly full sun all day).
- Think about the mature size and give it lots of room to expand.
- Pick a location with great drainage. If necessary, add compost to the soil.
- Plants won’t thrive if they are planted too close to a tree because of root competition and a lack of sunshine.
- Planting should not be done in open locations where strong winds could snap stems.
How to plant hydrangeas:
- By amending your soil with up to 15% organic matter and an all-purpose slow-release fertiliser, you may give your plant a good start (use half of what is recommended).
- Plant a little higher than you did while you were in the nursery container.
- In order to give the roots plenty of freedom to expand, the planting hole should be two to three times broader than the root ball.
- Before planting, gently untie the roots from their pots.
- Add the modified dirt back in and thoroughly water it.
- Planting in groups requires a minimum distance of 3 feet (more, if planting larger varieties).
Planting hydrangeas in pots:
- Put potting soil in a bag rather than garden dirt.
- Slow-release fertiliser should be added.
- For watering, leave 1 to 2 inches between the soil’s top and the pot’s rim.
- Make sure the pot includes space for the plant to grow and drainage holes.
Do hydrangeas like shade or the sun?
With the ideal balance of morning sun and afternoon shade, hydrangeas flourish. Even the sun-loving Hydrangea paniculata will thrive in some shade. Some hydrangea cultivars may survive complete shadow, though.
The oakleaf hydrangea, also known as hydrangea quercifolia, is a substantial species of hydrangea that may reach heights of up to eight feet. In a shade garden, this big bush makes a beautiful backdrop. The height will provide excellent midsummer seclusion. Oakleaf hydrangeas are summer bloomers with mostly white blooms, elegant oakleaf-shaped leaves, and lovely peeling bark.
Hydrangea anomala ssp. petiolaris is another choice for full shade. This climbing species, which has lacy, white blossoms in the summer, can reach a height of 50 feet if it is given adequate support. The foliage is a rich shade of green and would look wonderful growing up a tree trunk or covering the face of a building. It would also look lovely covering the roof of a garden shed.
Full shade cultivars require the same upkeep as partial shade. In the deeper shade, it will be especially crucial to keep the plants free of leaf litter and with excellent airflow. Water your plant once a week after it has become established. Keep a watch on the leaves, and if you notice any drooping, especially during the hot summer months, water them right away. The importance of this increases in hotter regions.
These leaves’ unique shape would be a lovely complement to Hosta leaves. The white blossoms would contrast nicely with the lighter hues of your shady blooms and provide some brilliant brightness to your shaded locations.
Shade Varieties
There are a few different hydrangea cultivars that thrive in the shade. Some types can even thrive in zones 3 (which doesn’t warm up until later in the spring), which is one of the coldest growing regions. Let’s examine some of the best shade selections!
Hydrangea quercifolia ‘Snow queen’
The movie “Snow queen” is stunning. The flowers are stunning, as they are with all hydrangeas. These rose blush-colored blossoms appear in the middle of summer. The foliage of this plant is my favourite component. The leaves begin the season in a very deep green, gradually changing to a deep reddish bronze colour, and finally finishing in that shade, offering a stunning splash of colour to your fall landscape.
Hydrangea quercifolia ‘Alice’
With a height ranging between 12 and 15 feet, this Oakleaf Hydrangea is one among the biggest. In the summer, this plant blooms with incredibly deep cream-colored flowers. A woodland garden would be a truly lovely place for “Alice.” This cultivar would look especially beautiful if it were grown as a bordering hedge.
Hydrangea arborescens ‘Annabelle’
‘Annabelle’ enjoys partial shade and has some of the largest flowers in the hydrangea family (12 inches wide!). These enormous blossoms can be supported all season long by the sturdy stalks. This shrub can grow up to five feet tall and five feet broad, so give it plenty of area to expand. These enormous, all-white blossoms bloom for a long time.
In a mass planting, as a specimen shrub, or as a foundation planting, “Annabelle” would look lovely. These bushes should still be included in your cutting garden. Imagine a bunch of flowers that large! Wow!
