I planted a new to me hydrangea this year (Bobo), and the bottom leaves are turning yellow. I've planted it in a bed that has phlox and other perennials in it that get watered often. The bed gets sun from about 10 a m until early evening. Too much water or too much sun? Any advice would be appreciated. It's such a pretty little hydrangea that I'd hate to lose it from too much attention!

Thanks,
Rose

Sorry for a late response Rose. I always thought Hydrangeas liked some shade, not quite sure how much. Also it could be iron chlorosis. See if this article helps.

I still have some yellow leaves, but they seem to be slowing down. I've just been picking them off. Maybe it was just from the shock of replanting, but they didn't start until a while after planting... I'll leave it and see how it does through the heat of the summer. May have to move it next year to an area with a bit more shade. It is getting some blooms on it, so may be okay!

I don't think you'll have to move it. Mine did that when I planted it. These can even take full sun here.

Mine do that when I plant them, also. I sell hydrangeas in my nursery, and they are right outside in pots inn full sun. Another nursery sells them under shade cloth, and mine actually look better.

We're actually zone 6a---not counting last winter, so yours should do fine.

Bobo is a hydrangea paniculata, and they are hardy as heck. I can't recommend a better shrub, unless maybe Limelight.

Thanks Polly! Bobo has done very well this first season, after the shock of planting, and I'd recommend this one as a must have! Lots of blooms for such a young plant! I do have limelight on my list...

hello my bobo is also experiencing the same problem , yellowing of leaves at the bottom of the plant. So, do i need to put iron in the soil
o I just need to wait and let the plant settled? Also, i want to ask how often do you water them now that the flowers already blooming?

Thanks a lot,
etl75 Thank You!

Hi etl75 and welcome!

I kept mine watered daily until it quit wilting the first year I had it, but I live in sand and things dry out really fast. Mine is doing great after baby sitting with it the first year. Now I just water weekly if we haven't had rain.

Hello Everyone,
I am new to this forum but I have a hydrangea issue.

I bought a Great Star hydrangea last year and planted it in my back yard. From then on it was down hill. the plant stated losing leaves and looked really terrible. As we got into Fall I cut the shrub back because it looked so poor. The plant did not come back out this Spring. I bought another Great Star last Saturday and brought it home and planted it in the same location that the one I lost was planted in. I amended the soil with bagged soil conditioner (looks like very fine pine bark mulch). As of today the base of the hydrangea is yellowing and I'm afraid that I'm going to lose this one also. The hydrangea will have been in the ground one week as of tomorrow. I have attached an image but I am not sure it is visible.

One thing that I would add to all of this is that I cut down and dug up a willow oak tree in the location where this and the first Great Star were/are planted. The tree was small enough for me to dig up the stump. It was not ground up but totally removed. Some roots probably are still there but not interfering physically with the hydrangea.

Should I move this bush or treat it with some kind of chemical/fertilizer/fungicide?

The bush gets direct sun from late morning until late evening.

Thanks for your help in advance.

I would just keep it watered well the first year. My Bobo is doing fine this year. I still have a small amount of yellowed leaves at the base of my shrubs in the heat of the summer, but I think that's just normal in the hottest, driest time of the year.

I bought 2 hydrangea trees which I planted about 6 weeks ago. One is doing great and the other has yellow leaves. They are in different areas. What am I doing wrong?

Welcome to NGA.

Are all the leaves yellow or just the older ones? You may not be doing anything wrong as it's common for older leaves to go yellow. I have several hydrangea trees and some do get the yellow leaves near the bottom while Pink Diamond, Tardiva and Limelight don't. Quick Fire is afflicted more often but only at the bottom = older leaves naturally die first. It doesn't do any harm to them and can be removed without any problems.

I have 2 plants 10 ft apart. The upstream plant's leaves are yellow and the downstream one has almost green leaves. What should I do to turn the leaves green? I applied aluminum sulfate 2 weeks back to the downstream plant.

Bring a leaf to your nearest nursery and get their opinion for a treatment. It may be lack of iron but I'd rather get their opinion.
