Of course, there is a right time to start and for some reason every year I have to sit and recall back to what I had done the previous season. Is it too soon to begin? When can I start, and what are the steps I need to remember so my plants and shrubs have the best chance to thrive?

Are You Ready to Begin Your Spring Cleanup?

I hope my list of 5 things to remember when caring for your panicle hydrangeas this Spring become a good resource for you to fall back on when we just need that friendly reminder on how to start. 

This list will be targeted towards your panicle hydrangeas because not all hydrangeas are the same, and panicle hydrangeas need different care then let’s say the big leaf type. 

1. Plan Your Pruning Around The Ideal Temperature

If you live in Zone 4b like I do, Spring seems to arrive at a later time than we all hoped it would.  There’s always that slight chance that we could get hit with more snow, so it’s important to pay attention to your last freeze date.  

When Should You Start Pruning Your Hydrangeas?

Even though panicle hydrangeas bloom on new wood, meaning the fresh green stems that emerge from your shrub that year will be the very stems you will receive those beautiful cone-shaped flowers on, it is still important to prune them annually.

So when is the right time?  The way I like to look at it, when it comes to pruning some of my plants is to imagine that they are in a deep sleep, so I like to try and make sure that any serious pruning is done before it has a chance to fully wake up.  However you also want enough time for the hydrangea to begin to form this season’s buds which will show you where you can start pruning. 

Look for Signs of Bud Formation

Panicle hydrangeas should start forming buds around the 50 degree mark, so when you begin to see your temperature steadily rising and keeping around this temp day to day, take a walk through your garden to inspect your hydrangeas.

If you notice they are starting to bulge then get out your pruners and get yourself ready for your first step in caring for your panicle hydrangeas this Spring. 

2. The ⅓ Rule: How Much to Prune

You may have heard or read others talk about the ⅓ rule in pruning because this is what the recommended amount that you remove from your shrub to be without causing too much shock or stress to the plant. 

If you do cause additional stress to the plant, there is a chance it may slow its growth that season and none of us want that. Also by cutting too much away, there could be less foliage, and with less foliage your hydrangea won’t absorb as much energy from the sun. Which in turn could cause it to limit the amount of flowers it would otherwise have provided you. 

What Is the ⅓ Rule?

So when you have your pruners in hand take a good look at the size of your shrub, and simply shorten it by ⅓.  Find the stems you plan to keep, with the shape of the plant in mind, and simply look for the nearest bud around the ⅓ mark and snip right above that at an angle. 

3. Shaping Your Hydrangea for Better Growth

Now that you know how much you can cut off of your panicle hydrangea, you can begin to decide if it will require some shaping. 

I like to consider panicle hydrangeas to be a low maintenance shrub, and they really are, in my opinion. You certainly don’t have to spend a great deal on shaping these, and you could just let them be. Although by doing so, you give them the best chance of thriving and becoming a strong plant in your garden. 

Cutting Back Fragile Stems and Encouraging New Growth

I like to begin by assessing the current stems, and picking out the ones that look most fragile. Go ahead and cut those back at the base if you want, so you can encourage the energy from your shrub to focus on its strongest assets. 

This will also help you get better access to the stronger stems you plan to keep, if you need to get back in there and snip a few more branches that might be a little more unruly like shown in the image below. 

An Exception to the Rule: Shaping Your Shrub for Stronger Growth

I know earlier I had commented on not cutting back too much to prevent shock or stress on your plant, but if it’s necessary to cut away a bit more than you’d like so that the stems aren’t growing against each other, I consider this the exception to that rule. 

You want to allow the plant stem room to grow and air to circulate, so you are providing it a better chance of success by snipping off those ugly branches that will eventually thicken and cause more disruption with the shape of your hydrangea. So what better time than any to sacrifice the plant for better health in the end.

4. Clean Up the Area Around Your Hydrangea

After all that pruning you have accomplished, unless you were cleaning up along the way, you should now have a mess of sticks and debris surrounding the base of your panicle hydrangea. 

Why Cleaning Up Is Crucial for Your Plant’s Health

Regardless of pruning or not, it is important to clean up the area around the base so that you prevent any fungal diseases or insects laying nests near your shrub.  I sometimes like to surround the base of my plants with fallen leaves during the Fall season to provide extra coverage so the ground around the roots of these plants stay warmer during our cold winter months. 

Not always do I get the chance of protecting my plants this way, but even still, the wind will likely have blown leaves and debris or even trash on occasion, so it is always best to clean up or pull away from the wood base so nothing is sitting against it. 

How to Break Up Stiff Mulch for Better Soil Aeration

I personally use wood mulch in my beds to keep the soil moist and prevent too many weeds from appearing, but there are times that this mulch can start to stiffen.  If you’ve worked with wood mulch you may already know what I mean, but if not, it basically becomes matted above the dirt and no longer easily moved.  When this happens I grab a garden fork or some sort of tool to break up the mulch to allow the soil beneath to breath. 

You will come to notice, I’m not a gardener that likes to purchase fresh mulch every season to replace or top dress, in order to make my beds look fresh and beautiful. Mainly because it’s added expense, extra work that takes time, but personally I don’t think it’s needed.  Yes it will look so much nicer, but is it helping the plants any more than simply mixing up the existing much I already have, as long as it hasn’t fully decomposed yet?  I think I’ll stick with what has been working and save myself the time and money. 

So whatever you may do in your own beds, just provide your hydrangeas a clean space to start growing, and this will give you a better chance of a good and full growing shrub that performs well in your landscape.

5. When to Fertilize Your Panicle Hydrangeas

Depending on when you got around to pruning, you may or may not be ready to start fertilizing your panicle hydrangeas.  Wait, why do I say this you ask?  Wouldn’t it make more sense to get all the Spring cleanup accomplished in one go? Sure, but there is a chance the fertilizer you spread could be wasted if it’s still too soon and the plant wasn’t ready to absorb the nutrients yet. 

Personally gardening isn’t perfect, and the only way we are all going to learn is by finding what works for you. I think I’ve fed my hydrangeas at all different times the past few seasons since they’ve been planted and I’ve had a successful year – however I’ve also learned a bit more each year and it starts to make more sense to me as time goes on. 

The Best Time to Fertilize Your Hydrangeas for Maximum Growth

If you want to provide the best chance for your panicle hydrangea to perform well this season, I would time your fertilizing out when the buds start to green up.  This shows you that your hydrangea is beginning to wake up, and beginning to actively grow.  When it reaches this phase, it will begin to absorb the nutrients and will need the energy to continue with its growth cycle. 

Choosing the Right Fertilizer: What Works for Hydrangeas?

I don’t have strong opinions on what makes the perfect fertilizer to use with your panicle hydrangeas at the moment, but I have started to use Epsoma’s Rose Tone Fertilizer this past Spring with guidance I received through YouTube’s Garden Answer channel where Laura has recommended this type since she’s been using it on her hydrangeas. 

Bonus Tip: The Importance of Soil Testing

Performing a soil test is always recommended when you don’t know what your soil conditions are, and having a soil test done will provide you with the best starting off point. With a soil test it will provide you the insight you need to determine what fertilizer your soil and plants will benefit most from. However I know not everyone will want to go through that added step, so if you find something that allows an equal N-P-K balance, you should be just fine. 

Should You Test Your Soil?

The fun and sometimes not so fun thing about gardening, is you get to know a little more about the science behind it all. If your plant is deficient in a nutrient there is a good chance it will show you through its foliage, or possibly stunted growth, so it is always good to pay attention through the growing season. 

If you are unsure what it may need, try snapping a photo of the plant as well as a close up of the foliage to show the exact coloring, and take it to your local garden center and ask if they are able to help you find the right nutrient that it might be needing to correct that issue. 

Feeling Better Prepared to Care for Your Panicle Hydrangeas this Spring?

Happy Gardening!🌿

I have a few of the varieties myself, and each of them have their pros and cons.  Some need more care than the rest, but I love having these in my landscape. Now that they are starting to get accustomed to the growing conditions my yard offers, they are beginning to thrive and grow much more than the prior years. 

Do your Hydrangeas start to flop once they’ve bloomed?

This year I noticed one of my varieties began to flop much more than usual.  For good reason too as these shrubs produced way more blooms than I’ve ever seen on them. 

Here is a picture of my Bobo Hydrangeas, that receive part-sun in our backyard. 

The first couple of years there had been fewer blooms, so I never had to address the floppy stems.  I also did not believe this variety to be so floppy, since I always thought only the ‘Smooth Leaf’ variety like the Annabelle was notorious for this… not a Panicle type. 

What Should I Do When My Hydrangea Stems Start To Flop?

Be Patient

If you notice after your hydrangeas start to produce blooms, and begin to lean away from the base towards the ground after a good rain, you may just need to give it some time for the water to evaporate during the day.  Most often your hydrangea will perk right back up on its own. 

*Caution* But Try Shaking Them Slightly

You may be thinking, I can just shake the excess water off to speed up the process and allow your hydrangea to spring back up much more quickly. 

This is correct in a way, but if you choose to go this route, be very gentle.  The stems, even though they can produce a very large bloom, are more than likely first year stems and not quite thick or strong enough to keep from snapping. 

Try Giving It A “Haircut”

This year when I noticed that my Bobo’s were not springing back up after several days of no rain, and nothing that should keep them weighed down like they were, I realized this plant just couldn’t handle all the blooms it had produced. 

I began to grow concerned about the shape my hydrangeas might be left with at the end of the growing season.  I did not want this to develop an unsightly shape next Spring, since with the panicle variety, you should really only prune off about a third each year. 

Step Back to Assess Your Situation

Looking my hydrangeas over, I could see many of my branches with first year stems had produced incredibly large flowers.  I grabbed my pruners, and began to snip off the entire bloom, right above a couple leaves, from the thin stems. 

This was hard for me to do as I wanted to keep these beautiful flowers, but I knew by removing the added weight, these stems had a better chance of growing stronger. 

Keep Only Part of The Bloom

Another thing I tried was snipping only half of the bloom off the stem, and it worked!

I still had a couple months of the season to enjoy these Bobo Hydrangeas, so I didn’t want to snip off all of the blooms just yet.  I began to start finding the stems that appeared thicker than the others, and snipped off only part of the bloom. 

Panicle blooms have the cone shaped flowers which gave me a decent length to work with, where I could just take my pruners and cut the bloom off from the middle, as shown in the picture below. 

This worked well in my opinion, and now I was left with ball-like blooms, which were still pretty. 

I also started to notice as I was giving my hydrangeas a good haircut, the stems slowly started to spring back up in place.  

They started looking even better the following day. My hydrangeas were much happier looking and I was no longer worried about the shrub having a permanent cascading arch of branches for the following season. 

Other Reasons Your Hydrangeas Could Be Flopping Over

Should You Water Them?

Maybe your hydrangeas are flopping over for other reasons that have nothing to do with heavy blooms, weak stems, and/or rain. 

Sometimes a hydrangea may simply be floppy because it’s thirsty.  If you know it’s been warmer with little to no rain, you could just be dealing with thirsty hydrangeas. 

If you know your hydrangea could use some water, just make sure to water at the base.  Watering from the top, may cause the leaves to scorch if the sun is still out. 

Some Hydrangeas Are Just Dramatic

As noted above, I have a ‘Big Leaf’ variety that appears as though it was dying during the day and if I don’t water it, the plant might just die for good.  However, later I would notice that same plant perked right back up like nothing happened after the sun moved past the trees and about to retire for the evening. 

Pay attention to this, as you wouldn’t want to be watering when it’s not needed.  If you have one of these drama plants, just wait it out and see if it’s happier once it’s shaded again.  

I still hand water a lot of my plants, so I usually keep tabs on which might need more water or perhaps need time to cool down.  Call it lazy gardening, but if I can prevent having to spend my time watering my plants each time they look like they are giving up, I’m all for it. 🙂

Whatever your reason may be, I hope my experience with my own has given you some ideas on how to fix your floppy hydrangeas. I plan to continue this pruning method, and see how it works for me in the coming years.  I may try to start earlier in the season as well and see if it can prevent any flopping to occur in the first place.
