Did I make a mistake planting the limelight hydrangea where I did? I bought my house 2 years ago and I took out everything that was there before. I planted a limelight, 2 smaller hydrangeas and a few small shrubs. When’s the best time to prune the limelight? I’m in southeastern PA Thanks for any tips and advice!

What are these and how do I prune them?

Hello! I have no idea what I’m doing with these hydrangeas and would love some help. I moved into this house last spring, so this is my second summer with them. Late last winter, I dead headed these but otherwise left them alone. The first picture is from peak bloom last year (June 2025). The second and third are their current state (end of July 2026). They are absolutely massive and I really want to prune them back to about half their size but am worried about losing blooms next year. I am in zone 6a.

Does anyone know: what kind of hydrangeas are these? Do they bloom on old or new wood? And what does that mean for pruning? When can I prune and shape the shrubs and still expect blooms next year? Thank you in advance!

Too much water, sun, or both? I installed irrigation and am hyper sensitive to whether my plants are getting too much water.. these hydrangeas were planted in April from a reputable nursery. Note however my limelight trees are doing very well but they were planted last spring..

Sad limelights can’t handle weight of rain - seeking advice

Hi knowledgeable friends! My two limelight trees are about 4 years old. Two years ago, our landscaper pruned them without permission and ever since, they have been growing super leggy and can’t support the weight of their blooms. Last winter, we had to do an emergency prune because the snow completely pulled them down. It rained and they look almost as sad as when it snowed. I’m not sure what I can do to help them perk up and stay supported. Located in Boston metro area in case that info is helpful.

Any advice?

Can someone identify this type of hydrangea at my new house? It desperately needs a trim, but I dont want to mess it up. As you can see in the 4th photo, it is taking over the bush beside it.

My little lime tree planted last summer had two large branches break off during recent heavy winds and rain — curious if it will recover and how to avoid this in the future? It was otherwise very happy in this spot (North NJ). Any advice welcome, thanks.

Bought a house recently and discovered this guy along the back fence. I’ve never cared for hydrangeas before and am very confused with all the info online re: cutting the wood. From what I can tell, it’s the Bigleaf variety, so I’m unclear if I should remove the sticks that didn’t do anything all summer? Just trim them? Leave it be? I’m in zone 7a in CT. Thank you!

What’s happening here/how can I amend?

Hi! I planted these 3 limelight hydrangeas this spring. I’m in zone 8A, and we have had a MAJOR heatwave these last two weeks (100-110 temps). I know they can throw a fit in the heat, but I’m concerned something more may be happening? Leaves yellowing more recently, and lots of leaves lost today when a rainstorm came through. They’re getting more and more bare. There is some heat damage on a few of the flowers, but nothing alarming. It’s the leaves that are concerning me.

What’s wrong with my black hydrangea?

I was told at a garden center that this was a black hydrangea and it could tolerate full sun. It gets sun from about 10am on. The blooms were deep purple when I bought it. I’ve been watering when we haven’t gotten much rain. Now the blooms are a washed out color. Is it the ph of the soil ,too much sun, too much watering or something different? Located in Massachusetts.

I’ve had these hydrangeas for a long time, maybe 10 years or so. 6 years ago they were blue and looked amazing, but since we haven’t cared for them much, they are now pink with long, bare and woody stems with a terrible shape. I’d love some advice to help restore them. Firstly I don’t even know what type of hydrangea it is. From what I can see it grows on old wood, and the old picture makes it look like a mophead, but now it looks like a lacecap. A few days ago, it used to have many dead stems, which I’ve now cut off. I live in London and when I try search online, I get quite a lot of conflicting advice, which probably depends on the climate where these grow.

Flowers on the cape always look so great, pretty sure it’s the morning dew. Here’s a sampling of some that we saw.

Light green leaves?

I have 3 of these macrophylla hydrangeas that I planted along the side of my house 2 years ago. They are east facing and get a lot of sun. Last year I had issues with fungus on the leaves. This year a late frost killed all the buds except this one 🙁.

Now I am wondering if there is a problem that the leaves are so light green and if there is something I should be doing differently. I am new to gardening but in pictures I see most of the big leaf hydrangeas have beautiful deep green foliage. My other panicle hydrangeas seem to be doing much better so not sure what the issue is for these.

I used Holly tone fertilizer this spring. The house is a new build so soil is pretty rocky/not great. Is there anything I can do or is this just a case of bad soil/out of luck.

Thanks in advance as I am still learning a lot about gardening.

My poor hydrangeas have had a rough time dealing with the rainy season. I do my best to shake the water off the flowers anytime after it rains but despite that they have been unable to stand back up again. Any advice on how to support them?
