Five Helpful Tips for Growing Beautiful Hydrangeas

June 30, 2020

These tips will help to grow hydrangeas with beautiful blooms!

Hydrangeas are one of my favorite flowers, but I didn't used to be so great at growing them. They hated me because I didn't know what they needed. :) 

I’ve learned a ton about the beautiful hydrangea over the years and wanted to share my knowledge with you!

Overall hydrangea shrubs are actually very easy to grow and take care of! They need very little care but are picky about a couple things.

When they are happy they grow FAST and will reward you with beautiful blooms. 

Tip one: Patience is needed

The sleep, creep, leap saying about plants is so true. The first year they don’t do much, the second the come along a little bit and the third they leap!

This limelight hydrangea plant is an example of one that absolutely took off after a few years. 

This is how it looked the first two seasons (it didn't even bloom):

And the third year it started to take off!:

You can see how much it grew just a couple of years later:

You should see this one now! It covers that whole window.

Overall, with hydrangeas you just need to have patience. Hang in there...they will reward you with beautiful blooms eventually!

Tip two: Don't give them too much sun 

Many hydrangeas like a good mix of sun and shade. 

Preferably sun in the cooler mornings and shade in the hot afternoons. Partial shade keeps them from drying out. 

These were planted on the afternoon/evening sun side of our home and did NOT do well:

hydrangea too much sun 

I’d had these for two or three years at this point. Not one had ever bloomed, they all barely grew, it was just sad.

I moved them to morning sun (afternoon shade) and look at the difference!:

The one on the left grew a TON from where it was (it was the smallest one). They don’t have a ton of blooms in this photo because I cut so many. ;) 

Always err on full sun exposure in the morning instead of the afternoon.

These are the mophead variety, and they have strong, beautiful leaves:

The leaves on that pink Endless Summer Hydrangea are especially hardy, dark and pretty.

Some can handle sun more than others though. I found some PeeGees on clearance years ago and was so excited -- they are basically a hydrangea tree. 

These thrive in direct sunlight!:

The PeeGee tree is a panicle hydrangea, like the limelight I first showed you. 

They have cone-shaped flowers that get HUGE:

Limelights like sun as well! 

If you are having problems getting yours to bloom -- try moving them to a spot where they’ll get some rest from the heat in the afternoon.

Tip three: Water, water, water

Hydrangeas need MEGA water. I mean, it’s in their name. :)

Hydrangeas are one of the few plants that take in water from every part of the plant...even their petals. 

I just watch mine -- if they start to wilt at all I know they need water. 

We are in Indiana (zone five) and I find they will do fine without regular waterings until about mid July when things get dry and hot. After that I keep an eye on them.

And of course, water newly planted hydrangeas or those in pots often!

They need a lot of moisture, but watch how you water them too. If you can, water at the base of the plant (not with a sprinkler) so the water goes right to the roots and doesn’t sit on the leaves.
Hydrangeas will not perform well in dryer climates. 

Tip four: Plant at the right time of year

Because hydrangeas need so much water, the best time to plant them is in early spring or fall. It’s hard to keep them healthy and hydrated if you plant in the heat of mid-summer.

Most of ours were planted in mid-October, when it can get chilly! But it's a great time because they can take root without fighting against the heat.

You won't believe how much our plants have grown at this house! Look how tiny they were when we moved in:

Look at them three years later!:

Another before and after -- you can see the difference on both sides of our sidewalk:

And here's a look at them four years in!:

Spring planting would be a good bet so you can enjoy the blooms all season, but you can get some killer deals later in the fall too!

Tip five: Not all hydrangeas need pruning 

I don’t prune (or cut down) most of my hydrangeas -- although you should clean some up a bit. 

Some hydrangeas grow back from the ground (on new wood), and the stalks they bloomed on the year before can be removed.

This can be tricky because sometimes it’s hard to tell between the two. This is an example of the type that grows on new wood:
hydrangea grow on new wood
The blooms on new wood come from new growth at the base of the plant.

I always pull those old stalks out of the ground (or cut them down) in the spring or early summer. You can leave them, but I think the plants do better when those are removed.

You won't want to prune these at all during the bloom time in summer. If you'd like to clean them up after the blooms die away, you can do so late summer or winter before the flower buds start to grow and open.

Some grow right back on old wood -- meaning they bud on stalks from the year before. 

Lacecap hydrangeas and mop heads (big round blooms) are bigleaf versions that grow on old wood:

Pee gee hydrangea trees

If you do want to prune old wood varieties, do so immediately after they flower (but don't do it much past mid-summer). 

But it's really not needed -- hydrangeas of all kinds do well without much work!

By the way, the endless summer variety bloom on new and old wood -- so if that confuses you, they are a great option! 

Bottom line, you don't have to touch hydrangeas much to have them do well!

Some additional tips for full blooms: 

  • Hydrangea do well in most soil types, even acidic soil. But the pH in your soil may change the color of your blooms. A low pH makes blooms blue, high makes them pink.
  • Because the color of your blooms depends on the acidity of your soil, you can change the color by adjusting the soil pH with additives from the nursery. If you want pink blooms, add hydrated lime to your soil. Add aluminum sulfate to make blooms blue. 
  • There are DIY methods too. I’ve heard burying nails and pennies work! (White blooms can’t be changed.)
  • You know those gift hydrangeas you find in the spring/early summer at grocery stores? They aren’t really meant to be planted. I had no idea! Go here to read more about that. 
  • Adding a good layer of mulch at the base of the plant will help keep the soil cool and retain moisture. 
  • Even though they love water, hydrangeas are prone to root rot. Make sure there is good drainage so they don't sit in standing water.
I was determined to figure out what made them tick because hydrangea are one of my all time favorites and I LOVE having them to cut and bring inside:

The limelights and PeeGee hydrangea blooms turn the most beautiful pink/green in the early fall -- they are just gorgeous! 

I used them in our pergola reveal years ago:

I hope that helps any of you who have struggled with growing this beautiful plant! 

I think the change I made that made the biggest difference was where I planted them -- the amount of sun is key with some varieties.

  1. Hydrangeas are my favorite flowers too! I received one as a birthday present last year but I think it's too far gone to save at this point. It was a small plant, I never took it out of its plastic pot and I read that it needed a good freeze in the winter so I left it outside. (I live in ND, by the way) Now the branches are bare and light brown - not a leaf in sight. I think I killed it! :( I haven't bothered to water it so I'm not sure if I can bring it back to life. What would you do? Think it can be saved? Thanks for all the great tips - I've pinned it to my gardening pinterest board for later.

  2. Thanks for the tips! I'd love to plant some hydrangea. I am thinking of planting some on the north side of my house. Hopefully, that will be a good spot to put them!Hydrangeas make great cut flowers.

  3. Grat post! Your yard is beautiful! I hope to have mine looking this good one day!!!

  4. You've inspired me! I have 2 hydrangeas that have done NOTHING for years. I'm moving them this fall to a afternoon shade location.

  5. I have one of the climbing hydrangeas which I planted next to my oil tank so that it would cover it.... and for three years all it did was grow out the other way! This year it has decided it should behave itself and has started to climb over the tank, but with a really hot spell of around 3 weeks the flowers were out and over in days. Never mind, it looks healthy and is doing what it was meant to do! Some of them take years to flower, I have another which is white with a red edge t0 every petal, and now 7 (yes, s.e.v.e.n) years after planting, it is blooming - Yay!!

  6. Here is what I've discovered over the last five years now of growing these guys. 1.)I don't prune them. 2.) They seem to prefer the north/east facing side of my house that only gets some morning sun. 3.)Hydrangeas whatever cultivar they are, seem to prefer drip irrigation. If I water them from above the sun scorches the leaves. Right now I have 'Wedding Bells' blooming, 'Sister Theresa' and several unidentified pink and blue ones. Love going to Lowe's and 'saving' the Hydrangea's on the clearance rack. I got two for $7 a few weeks ago. My husband says I'm not a plant missionary and obligated to 'rescue' every mistreated plant at big box stores...Ugh. Men.

  7. I'm glad to see your hydrangeas are doing better. Um, I think I am the number 1 worst hydrangea parent, not you. lol. My girls gave me several Endless Summer hydrangeas for Mothers day at least 7 years ago and they look like your pic with the sticks sticking out of them. Last year I moved all but one of them and most of them (even the one I didn't move) has doubled in size and even had a few blooms. I live in Charlotte and everyone around me has huge, fabulous hydrangeas. Oh, and Azaleas too...but my Azaleas won't grow either. Your yard looks fabulous and I hope your hydrangeas continue to grow!

  8. I had gorgeous hydrangeas when I lived in Virginia. They had full sun most of the day but late afternoon had some shade. The hydrangea I planted here in Pennsylvania is just pathetic. I am sure the sun is just too hot for it. I covered it early in the spring with a deck chair just to keep the leaves from burning. In the fall I am going to move it near a tree in the garden. It will still get sun but hopefully not enough to bake it! By the way, my niece got married Friday night. She and her maid of honor carried bouquets of hydrangeas from my sister's garden and I used all hydrangeas (3 different varieties and colors) on the tables at the reception. They were gorgeous...if I do say so myself!

  9. Yours are looking great! My question - do you know if you can move an established hydrangea? We moved in april, and the house has this enormous GORGEOUS blue hydrangea right in the middle of the backyard. I mean...smack dab in the middle. So strange. That said - I love that plant, just not its placement. The plant is easily 5 feet across and just blooms like crazy, the last thing I want to do it kill it, I just wish we could somehow move it?!

    2. I've read moving them in late fall or winter is best but I think any time when there is no danger of them budding is probably fine!

  10. Hydrangeas are my jam. I want to propogate some from my neighbor's bushes in the Fall then put then along the side of our house next year. It's the perfect spot for them--a little sun in the morning and shade the rest of the day.

  11. I love hydrangeas! The perfect flower. Fresh, in between or dry/drying they are perfect. Seeing your long boxy thing again under the TV filled with the hy's makes me want to make one. You always find the most fun filled things to use in it.

    My hy's had blooms on them when purchased, but it took two years for them to bloom again. The only thing I do is use a hydrangea fertilizer each spring and fall.

  12. I love hydrangeas too. I tried, unsuccessfully, years ago to grow one. I am renting where I live now and didn't want to invest in plants we would be leaving behind until a neighbour (who owns a landscaping business) offered to get me a decent sized one for really cheap. It is doing great and I love it!!!!

  13. Do you know how to dry them out for dried arrangements???

    ReplyDelete
  14. Beautiful! I love ours. Totally agree...they love water, most hate full afternoon sun, bloom on dead wood. Guess I got lucky, my limelights I planted in May are blooming nonstop!

  15. I'm in southern IL near St. Louis, and the best thing I have found for my hydrangeas was Daconil fungicide. You can get it just about anywhere, and it has made a world of difference on my plants.
    Also, I have the endless summer variety and my husband accidentally cut one of my plants down to the ground when it was dormant early this spring. I thought it was done. Well, now it looks better than it ever has and bloomed like crazy! Guess all varieties are different!

  17. Your hydrangeas look amazing! I have about 12 and some of them are doing great and some are just creeping along. I try to water them deeply every chance I get. I am wondering if you have ever fertilized yours and what you've used for that if so.
    Also I have never heard of the hydrangea tree that you mentioned but I'm going to look for one this fall. So pretty. Thanks so much for sharing!

  19. Thanks for the tips. I just moved into a new house and am excited to plant some hydrangeas. After reading your post, I will probably wait for Fall.

  20. I didn't know sleep creep and leap applied to anything but ivy. :/ Maybe that is why my one hydrangea looks better than last year but not leaping yet. Hopefully next year. :)If it does good I'll try a second one. My thumb doesn't seem to be very green. Question...where did you get the green lamps in the last photo?

  21. Excellent post! Absolutely love hydrangeas and have a hard time growing them in deep Texas....it's just so dang hot but mine are in dabbled to full shade all day and I'm keeping them watered so we'll see! Thanks for the tips!!~~Angela

  23. I also live in Indiana and have two hydrangea bushes in my front yard. This is the 3rd summer that we have had them planted there. Of course like you said this summer has been wonderful weather, and I was really hoping that they would bloom. The bushes got huge!!!! However, they barely bloomed. Nothing like those big mopheads. My husband and I were thinking about taking them out this fall since they just get to be huge overgrown bushes and not much else. What are your thoughts? Should we stick it out another year?

    1. Hey! Just saw your question, sorry! I would wait one more summer...after that you'll know if they are going to bloom for you! My limelights took years so hang in there one more year! :)

  26. Thanks for info. I am getting so discouraged with my plants....ordered from QVC and all 3 have not grown in first 6 months. I wrote the landscape company and they said that is normal for first year but should see a huge growing spurt in spring. They showed those babies on TV getting huge by end of first year. Here is hopping. It is strange to see something stay green and not grow at all. I love, love them so keep your fingers crossed for me:)

  27. We moved into our new home at the end of May, and discovered that the back of the yard is lined with several HUGE hydrangea bushes. They are all blue. ha I love them! I got so many for our table vase, etc. while they were blooming. A lot of the reason we chose our current home was because of the beautifully landscaped yard and huge trees! We love plants. :-)

  28. I love hydrangeas, but I always end up killing them in my Cali heat. This year has been my most successful year yet, and I think it's because they are in my completely shaded front porch. Next year, I'm going to try to plant them in the back yard!

  29. Please DON'T move your petiolaris(climbing) hydrangea, or you will need to strt waiting for blooms all over again. They often don't bloom for at least the first 5 yrs after transplanting.
    Your macrophyllas (Endless Summer) varieties should not be cut back at the end of the growing season, as they bloom on 'old' & 'new' wood. Regularly cutting blooms for bouquets &/or deadheading promotes continual blooming.
    The arborescens (mop heads) can be cut back to 6-8" in late Fall and they will reward you with healthy new shoots each Spring that will support loads of big, fluffy, white to green blooms--they bloom on new wood.
    The paniculata tree varieties should be deadheaded in early Spring & prune out low-growing suckers as they emerge.
    I live in IL, so my climate in z5 is similar to yours in IN. In addition to plenty of water, I have found that macrophyllas reward me with tons of flowers when I mulch them with leaves after the first freeze.
    All hydrangeas require rich, humus-y soil full of organic matter. They definitely don't care for our heavy, clay in the Midwest, so soil prep is key to successful hydrangeas. Happy gardening!

  30. Thanks for the tips. This is one plant I've never been able to grow & I absolutely love them. I have one in a pot on the patio that I've managed to keep alive since Easter. No new blooms since then but new growth.

  31. I love your postings. We landscaped our front yard and we could plant any hydrangeas due to full sun, so I am hoping in spring I would be able to plant hydrangeas in our backyard and side of the house. I love these plants with passion. I really enjoyed your insights.

  32. I got my 3 from a nursery that raises only hydrangeas. She had a variety of them! Some are more costly (over $100 each) and others around $30 each. I have even seen a yellow variety!
