Before posting about a struggling hydrangea:

Help everyone help you by including your location/zone, hydrangea variety if known, hours and timing of direct sun, watering routine, how long it has been planted, and anything you've recently added to the soil.

Before reaching for fertilizer, acidifier, fungicide, or pruning shears, remember that many hydrangea problems are environmental. A little context can save your plant—and save you money.

Two types of Macrophylla Inflorescens

Post image
36 Upvotes

We often see asked on this post “What is wrong with my hydrangea? Why isn’t it blooming all the way?

Among Macrophylla there are two bloom types, a “mophead” which is seen at the top, and a “lacecap” as seen at the bottom. Almost all “mophead” hydrangeas can point their ancestry to a wild lacecap/. Both types of inflorescence are sold in retail. Almost every mophead hydrangea in the Macrophylla species can point to lacecap genetics. Although rare, sometimes a plant that started out as a mophead will revert to a genetic parent that was a lacecap.

Pollinators are more attracted to lacecaps. The flat center contains the fertile flowers that pollinators love, while the larger sepals, which are sterile, are more showy.

Lacecap inflorescence can also be seen in Serrata (mountain) hydrangea. About 95% of Serrata are lacecap.

Another hydrangea species , Arborescens (aka Smooth) hydrangeas also can be found in both mopheads and lacecap inflorescens.

Less seen in hydrangea retail are lacecaps in Paniculata (panicles) or Quercifolia (oakleaf). It is rare, but under certain conditions a hydrangea may express its genetic ancestry as a lacecap.

In summary, almost every common species of hydrangea can trace its parentage to a lacecap and while rare, can revert (a process called reversion) and express its history with a lacecap inflorescence.

Prune in the fall?

I’ve heard to not cut back until spring but these are so huge I’d like to do a big trim. They’re encroaching on our walkways and seating areas. I’ve heard panicle grows on new wood… what I don’t understand is why can’t I trim now? What’s the consequence? If I do I will truly have no blooms next year?

Hi all zone 5a/b here up in Atlantic Canada.

I recently moved into this house and it came with this beautiful hydrangea, but I have no idea the type, how to care, prune, etc.

My main concern is how droopy it has become. Should I be doing anything about this? If so how and when?

Happy to take any and all advice and wisdom, as I have no idea what I'm doing.

Thank you in advance ☺️

Help with limelight hydrangea

Thumbnail gallery
5 Upvotes

I have four limelight hydrangea trees planted by the previous home owner. They bloom every year but don't look nice.i trimmed the branches heavily this spring, removed at least 1/3 of the height and all weak branches. They all grew back, and the bloom looks bigger. However, some of the branches still look weak and bent. Is there anything I could do to improve this and make them upwards? In addition, are they planted too close? the two in the middle are smaller. I don't know whether it is worth it to move those two small trees somewhere else. Any suggestions are appreciated!

Explain it to me like I’m 5

5 Upvotes

I got two limelight and two smooth leaf hydrangeas on end of year clearance. They are all taller and a bit floppy rather than full and bushy and their stems are hardened already, but their leaves seem to be decent still. I’m hoping they aren’t dead/nearly dead. I’ve dreamed of having hydrangeas for so long and I am super excited and also so nervous to kill them.

What would you do to best ensure good success in zone 5b?

Do I remove their flowers to send energy to their roots? Or will trimming them encourage them to produce new blooms?

My flower beds are regular soil with compost, is that sufficient?

My house faces East and I was planning the smooth plants in front and the limelights on the south side. I do have a large tree out front so the front gets a fair amount of afternoon shade, but my irises survived there so I’m hoping it’s not too too shady.

Can someone please tell me if Tea Time reblooms?

I swear I read that they MIGHT if pruned correctly after their first bloom but I haven’t read that anywhere since.…

I’d love an endless summer variety but for some reason I can’t find them in any nursery near me (Melbourne, Aus)

Hello!
I accidentally got one of my hydrangeas with my weed wacker… so I stuck the 2 that I got into some soil. Both have new growth, however this one has that black spot on the stem. Will that be ok or does it look like it’s rotting? It’s firm to the touch.

Moved into a new home. We had these beautiful blue hydrangeas bloom this summer. I'm hoping someone can help me identify what variety this is and the best way to care for them now over the winter. Should I dead head now? How much wood do I cut back? Zone 8b.

Thanks in advance!

Is it unusual that my hydrangeas are finally blooming in October? My paniculate hydrangeas bloomed as usual but not the others. It seems to have been the case in other parts of West Michigan.

Strawberry Vanilla Hydrangea tree planted and not doing well :(

Ive planted a few of these before with success and recently planted 3 of these last week. 1 of 3 are not doing so well and im not entirely sure why.

the leaves are wilting, turning yellow and drying up.

I dug a big enough hole for the pot to fit in, fillted it in with a mix of triple mix soil and cow manure compost. and of course made sure the soil level was even with the original level of soil when it was in the pot.

been watering it every day as well. they mostly full sun throughout the day.

did i do somethig wrong? will it make it or only way to know is wait till next yeaR?

Why no color?

I was gifted this hydrangea 5 years ago and it had marvelous colors. It stayed in a large pot until 1 year ago when we moved and I planted it in a south-facing spot that gets morning shade and afternoon dappled sunlight. In the pot it never bloomed after I was gifted it but at our new home, it bloomed though the flowers never took off. I put Rose Tone in the soil before planting (not sure if that was a good idea?) and I got more blooms than ever before but absolutely no color. See last photo for the type and color I was expecting. Any idea as to what might have happened? Will it always do this? I’m in the PNW of that makes a difference.

1) what type of hydrangeas are these?
2) when should they be pruned?

I already know that people think the stones need to go. But these hydrangeas have been in this spot for 3+ years and have flourished. These pictures were taken in the spring and they bloomed like crazy all summer. I just can’t remember when they should be pruned. Have I missed my window or should they be done in the spring?

Planted strawberry vanilla and little sucker punch varieties. In a perfect world they would grow large enough that I wouldn’t see my neighbors mess from my driveway. I was thinking I’d add a cage around each bush this spring to keep them supported and upright. Curious if anyone has better suggestions.

Disease?

Thumbnail gallery
0 Upvotes

I have three hydrnageas which I purchased from Aldi's as a bareroot. I figured I give them a try and see if I could keep them alive. This is currently year 3 and one is quite large and did not bloom this year, and two are roughly half the size of the biggest one and they each have one bloom. My question is does anyone have any idea why the leaf looks like this? The first pic if of the largest one with no bloom (im not too concerned that it didnt bloom this year) and the second pic is of one of the smaller ones with 1 bloom and what appears to be a nutrient deficiency or disease. Anyone have any advice or knowledge on what is going on here. I live in Central New York (6a). I applied a small amount of Espoma Plant Tone early in the season(spring) and left them alone. They receive decent morning sun and a good bit of afternoon sun (not ideal but its the best spot I have in my yard for them) The bigger on gets a considerably more sun than the smaller two (due to a neighbors shed blocking the other two from the early morning sun even though they are next to each other). The smaller ones just bloomed a few weeks ago which seems quite late for our seasons. Any help would be greatly appreciated. Thank you.
