How to Use The Original Endless Summer® Hydrangea in the Landscape
This wonderfully showy, smaller landscape plant has gained the respect of landscape architects over a wide range of hardiness zones. Large rounded flowers begin blooming in late spring and continue to be showy right into winter.
Use The Original Endless Summer® Hydrangeas as lovely foundation plants. They look wonderful when flanking either side of a front entrance.
They are amazing when repeated across the middle of your mixed shrub borders. Include them in your perennial gardens to add bold texture and bright color all season long.
You can also plant them in large containers. Decorate your entryway, use it on the pool deck or patio, or move them around anywhere you need a pop of color. They'll give you armloads of blooms for cut flower arrangements, too.
Try planting The Original Endless Summer® Hydrangeas as smaller informal hedges for a phenomenal look. Use along a walkway or fence to easily boost the charm!
For a tight, solid hedge, plant them 2 - 3 feet apart on center. Measure from the center of one to the center of the next. You can also stagger the planting for a larger impact. Use a double row, planted in a zig-zagging pattern.
Take that concept a step further by creating a colorful mass planting to cover a wide, open area. Zig-zag the planting pattern and keep the bed weeded until the plants grow together. A simple trim in late winter is a small task to pay for the incredible show they put on.
Mix things up with other Hydrangea varieties! Try another mophead Summer Crush® Hydrangea or the radiant Blushing Bride Hydrangea! The soil pH will give you a vibrant range of pink flowers or blue blooms for you to enjoy! Or Twist-n-Shout® Hydrangea for Lacecap blossoms in pink or blue. Or try Limelight Hydrangea for steady lemon-lime blooms regardless of pH!
#ProPlantTips for Care
Growing in USDA zones 4 through 9, the Original Endless Summer® Hydrangea is a nice size shrub with showy, rounded mop head flowers when grown with a few simple requirements.
It grows best with morning sun access to dry the leaves. Planted in well-drained, slightly acidic and evenly moist soil. For the best display of leaf and flower color, give them an even amount of water regularly each week. Dry spells will cause leaf and flower browning.
In warmer climates, please select your planting site carefully to protect plants from the extremely hot afternoon sun. In the warmest summers, full sun in the afternoon might scorch these pretty plants.
The east side of a building or fence is usually a good option. Or, give them a spot where they will receive partial shade from a larger tree.
Each year, just as they start growing, trim the old flower heads back to healthy buds along that stem and any broken or damaged branches.
Be patient with The Original Endless Summer® Hydrangeas in early spring. They do require warmer soil and air temperatures to start growing.
The bloom color will depend on soil conditions. Test the pH level of your soil.
Want pink blooms? Add lime following directions to increase alkalinity.
Want blue flowers? Add Sulphur to slowly drop the acidity and use Dr. Earth Acid Lovers Organic and Natural Premium Fertilizer in early spring and around the 4th of July. Use pine bark mulch which will slowly break down and help increase soil acidity.
In Zones 4 and 5, provide extra mulch late in the fall. Just dump it right on top of the stems, like you do your Rose bushes. As the plants start to wake up in the spring, carefully pull the mulch away from the stems.
You'll love the outstanding ornamental value and disease resistance from these game-changing gorgeous blooming Hydrangea bushes. Yes, they really do keep producing flower buds all summer long.
Just look at your summer pictures! You'll see the blooms covering these hardy plants all season long. They bloomed all summer to decorate your yard.

Very first time planting this flower, coming from Houston Texas. I was a little nervous since these plants require a lot of care and water but she has been doing so well!!! I water her twice. Early morning before work (6am) and after sun down (after 7pm). I placed some mulch on the pot so that has been helpful at keeping the soil moist. I was really afraid of drowning her or giving too much water mostly in the early afternoon where the sun was starting to burn through leaves due to me giving it water at 5pm. Shes blossoming beautifully and cannot wait until shes fully open. I also recently purchased her back at the beginning/mid May. Very fast shipping too!
Hi there! Thank you so much for taking the time to leave a review for our Endless Summer Bigleaf Hydrangea. We're so happy to hear that it's doing well in your care and that you're taking such good care of her. It sounds like you have a great watering routine in place and the mulch is definitely a helpful addition. We hope you continue to enjoy watching her blossom and thank you for choosing our product. Happy gardening!
Hydrangeas had a little trouble adapting but seem to be doing fine now
Transplant stress is pretty common with hydrangeas, so it's good to hear yours have settled in and are finding their footing. Once they're established, Endless Summer tends to be a reliable bloomer season after season. Thanks for the update, Kathleen. The Nature Hills Team

We take great care in ensuring our plants arrive safely to our customers. Happy Planting - Nature Hills Customer Support
I am not sure if i am happy, tge plant came to me in full bloom. I was always told you never plant/repot or otherwise disturb plants until they are done blooming. It also is white, not blue (i was not told how to change the soil to make it blue), if that is even what needs to be done.
Debra—great question!
We truly appreciate your honest feedback and understand your hesitation.
Receiving a plant in full bloom can be a bit surprising, especially if you’ve heard that it's best not to disturb blooming plants. Fortunately, hydrangeas are quite resilient and the Endless Summer variety is bred to bloom on both old and new wood—so even if transplanted while blooming, it typically rebounds beautifully with continued care.
As for the flower color, you’re absolutely right that soil pH plays a big role! To encourage those iconic blue blooms, your soil needs to be more acidic (ideally with a pH between 5.2 and 5.5). Adding soil acidifiers such as aluminum sulfate can help shift the bloom color over time. We’re happy to walk you through this process if you’d like!
1. Coffee Grounds:
Used coffee grounds can gradually lower soil pH while also adding nitrogen. Just sprinkle them around the base of the plant and lightly work them into the top layer of soil.
2. Pine Needles or Pine Bark Mulch:
Both are naturally acidic and make excellent mulch that not only helps with pH but also retains moisture and suppresses weeds.
3. Compost with Fruit Scraps:
Compost that includes apple cores, citrus peels, or other acidic fruit waste can nudge the soil in the right direction while improving its overall health.
4. Peat Moss:
Incorporating peat moss into the soil is another highly effective and natural way to lower pH. It’s especially useful if you’re amending the soil before planting or during repotting.
5. Sulfur-Based Organic Products:
While not “kitchen” natural, elemental sulfur or products labeled “organic soil acidifiers” (often derived from natural sources) can safely and steadily reduce pH when used according to label directions.
Keep in mind, the change won't be instant—natural methods take a bit of time, but they’re plant-friendly and sustainable. A soil pH test kit can also be handy to track your progress!

I planted my hydrangeas about a year ago and they’ve gone from small and spindly to lush and beautiful. They are extremely thirsty plants, so I have been navigating that aspect, and I am nervously preparing to transfer them to larger pots to encourage more healthy growth!
Hello Marissa,
Thank you so much for sharing your wonderful progress with your hydrangeas! It’s fantastic to hear they’ve transformed from small and spindly to lush and beautiful in just a year. You’re absolutely right—hydrangeas do have big appetites when it comes to water, so managing their thirst can definitely be a bit of a balancing act.
Transferring them to larger pots sounds like a great next step to support their continued healthy growth. When you repot, be sure to choose rich, well-draining soil and try to maintain consistent moisture without letting the roots sit in soggy conditions. Additionally, making sure your pots have adequate drainage holes can prevent overwatering issues.
If you’d like, we also have some detailed hydrangea care guides and watering schedules on our website that could help ease your transition to bigger pots.
Please don’t hesitate to reach out if you need further tips along the way—we’re always happy to help!

We purchased sixteen of these hydrangeas in the #3 containers and they arrived looking absolutely beautiful. Thick and full, with plenty of blooms. I had never ordered shrubs by mail before and was totally floored. We’ve since planted them all and they’re thriving. I tell everyone who asks about nature hills! And will definitely be back in the spring to order more plants!

Hi David,

We’re really glad to hear you were able to get them successfully planted and that they’re doing well so far in Door County. It sounds like you’re giving them a wonderful start, which already puts you ahead for the spring growth to come.

Dear David,
Thank you so much for sharing an update on your Endless Summer Hydrangeas! We truly appreciate you planting them and taking the time to let us know how things are going so far. Winter in Door County can be quite the test for many plants, but these hydrangeas are known for their strong resilience when planted in appropriate conditions.

I couldn't believe the blooms on my plants...:I have 4 on my porch and with all 4 in bloom at the same time it was mesmerizing! I couldn't have asked for the health and production of blooms.My problem is not knowing how to prune after the first blooms begin to fade. The beautiful pink blooms have turned "green"?....:do I trim these blooms off to make room for more of the beautiful pink? Also, my leavesare beginning to get brown spots and brown edges......what do I need to do to regain the nice, green, healthy leaves I had at the original blooming season?
Hello Nanny,
Thank you so much for sharing your wonderful experience with the Endless Summer® The Original Bigleaf Hydrangea! It’s truly heartwarming to hear that having four blooming plants on your porch created such a mesmerizing effect. Your care and enthusiasm definitely shine through your glowing review.
Regarding your question on pruning after the first bloom fades—yes, it’s a great idea to trim off the faded green blooms to encourage a second flush of those lovely pink blossoms. To prune, simply cut back above the first or second set of healthy leaves below the spent flowers. This helps redirect the plant’s energy into new growth and bloom development.
The brown spots and edges on your leaves could stem from a few possibilities such as leaf scorch due to too much sun or inconsistent watering, mites, or a fungal issue. Ensure your hydrangeas receive partial shade and consistent, deep watering (preferably in the morning) to keep leaves healthy. You might also inspect the foliage for tiny pests and consider applying a fungicide if fungal infection is suspected. Removing affected leaves can help prevent spread.
For detailed guidance, our Plant Care Library has an excellent article on hydrangea pruning and leaf care that you may find useful: https://www.naturehills.com/hydrangea-care

Hello Nanny,
Thank you so much for sharing your wonderful experience with your Endless Summer® The Original Bigleaf Hydrangeas! We’re truly delighted that you’re enjoying such a spectacular bloom display on your porch—it sounds absolutely magical with all four bursting at once!
Regarding your questions about pruning and leaf care: when the pink blooms begin to fade and turn green, you can gently trim these spent flowers to encourage your hydrangea to put energy into new growth or future blooms. However, Endless Summer hydrangeas bloom on both old and new wood, so heavy pruning in late spring can reduce blooms later in the season. It's best to prune lightly these faded blooms to keep the plant tidy, and a more structured pruning (removing dead or weak stems) in late winter is recommended.
For the brown spots and edges on your leaves, these can be caused by a few factors such as too much direct sunlight, inconsistent watering, or fungal issues. To help your leaves regain their vibrant health, try:
- Ensuring consistent moisture—we recommend watering deeply but less frequently to encourage healthy roots.
- Providing some afternoon shade in hotter regions to prevent leaf scorch.
- Improving air circulation around the plants by spacing them well.
- Checking for pests or fungal diseases and using organic fungicidal sprays if needed.

I love the color and beauty of the flower but I had it in full sun and had to water 2 -3 times a day. Moved to 75 percent sun and still water about twice a day. I do have a real clay base soil, could that be the problem?
Hi Sue,
Thank you so much for sharing your experience with your Endless Summer® The Original Bigleaf Hydrangea! We’re delighted to hear you love its color and beauty.
The watering frequency you’ve mentioned does sound partly related to the clay soil being heavy and potentially poorly draining. Clay soils often hold water longer but can also become hard and compacted, making water absorption challenging and possibly causing your hydrangea roots to dry out more quickly if irrigation isn't absorbed deeply. Moving your plant to a location with a bit of afternoon shade was a great decision since full sun can increase water loss through evaporation.
To improve watering efficiency and soil conditions, you might consider amending the planting area with organic matter, such as compost or aged shredded leaves, to help loosen the clay and retain moisture while improving drainage. Applying a 2-3 inch layer of mulch around the base can also conserve moisture and protect roots from heat. Additionally, watering deeply once a day (preferably early morning or late evening) encourages roots to grow downward rather than staying shallow, reducing frequent surface drying.
We hope these tips make your gardening little smoother and your hydrangea happier! Feel free to reach out with any other questions – we’re here to help.

Hi Sue,
Thank you so much for sharing your experience with your Endless Summer® The Original Bigleaf Hydrangea! We’re glad to hear you love the color and beauty of the flowers—it’s truly a stunning plant.
Regarding the frequent watering, clay soil can indeed impact water drainage and retention. Clay tends to hold water longer but can also become hard and compacted, making it difficult for water to reach the roots evenly, which could cause your plant to either dry out quickly or retain water unevenly. Moving your hydrangea to partial sun was a great idea since this reduces evaporation and stress.
To help, you might consider amending your soil with organic matter, like compost or peat moss, to improve aeration and drainage. Adding a layer of mulch around the base can also help retain moisture and keep soils cooler. Ensuring consistent but not excessive moisture is key—checking the soil moisture by inserting your finger about an inch deep can guide you better than a strict watering schedule.
If you’d like, we have a detailed care guide on hydrangea soil and watering tips that you can find on our website to help tailor care specifically for clay soil.
Thank you again for your thoughtful feedback—your garden’s well-being means a lot to us!

Hi Rhonda,
Thank you so much for sharing your experience with the Endless Summer® The Original Bigleaf Hydrangea! We're thrilled to hear that it keeps blooming beautifully and that you're enjoying the lovely color variations in your soil. Hydrangeas can indeed be such joy-bringers with their ever-changing hues based on soil conditions.
If you're ever curious about how to enhance or maintain those vibrant pops of color, one tip is to monitor your soil pH – more acidic soil can bring out bluer tones, while alkaline leans pinker. Adding amendments like aluminum sulfate or lime can help tailor the palette, if you’re interested in experimenting.
We're excited to hear about your garden’s success and are always here if you need advice or plant suggestions for complementing your hydrangea blooms!
