Best thing to do is prune out the dying branches, disinfecting the pruners between cuts and disposing of the prunings. I have had some success I think using AgroFos as a preventative spray. There are similar products with different brand names and they are very safe.
Keep plants well watered, but not soggy - provide good drainage - and as stress-free as possible during the growing season. Many rhododendrons are capable of growing and blooming by outgrowing the infections, but others are highly sensitive and can eventually die. I don't know where you live, but here in Pennsylvania where I live we had a very dry winter and not very cold.
This resulted in a lot of drought damage which usually manifests itself as dieback. When the plants become stressed lesions form which cause dieback. As akamaine said, the best solution is a healthy plant. Yes, do cut the dead branches off to keep the infection from spreading. A certain amount of dieback is almost unavoidable unless you can water during a drought, even a winter drought.
I'm in southern Ohio. We had a mild winter this year. We had pretty normal amounts of rain but I'll keep an eye on them now that I've cut them back. To my surprise, they are blooming. First photo is the one struggling and the other is one that is healhty next to it. Hi all, it seems some are still replying to this old thread, so I can definitely use some help! I have a sort of hedge of 6 very well established rhodies, at least 20 years old, if not much older.
The plants look very healthy and get tons of new green foliage, but of my 6 plants I only get about a dozen blooms. It's so frustrating because I look around the neighborhood and everybody has wildly blooming rhodies. My hedge is south facing under 3 65 year old maple trees, so they get filtered sunlight most of the day. Every spring and fall it looks like I'm getting flowers covering the plant, but instead it turns into leaf.
Thanks in advance for any help. Vigorous vegetative growth with sparse flower buds and bloom is usually the result of excess nitrogen. If you're fertilizing every year almost certainly unnecessary , you're encouraging green growth at the expense of flowers.
Rhododendrons set buds on new wood soon after the spring bloom finishes. These buds must stay on the plant until the next spring to produce a flower. If they are in shade or you have a summer with mostly cloudy days, bloom will be reduced or nonexistant. We had a very cloudy summer a couple years ago and everyone complained the following spring that their bloom was very poor. Some varieties will bloom in moderate shade, but many varieties need 6 to 8 hours of sun each day to set flower buds.
Lawn fertilizer is notorious for having lots of nitrogen and lots of nitrogen forces lots of leaf buds and discourages flower buds. Great if you like a green rhododendron with no flowers. It is best to just use a good rhododendron fertilizer just before bloom in the spring.
Apply at half the recommended rate and just once. Every rhododendron has a rating, a temperature that is considered safe for not destroying flower buds over the winter. In Pennsylvania where I live, I choose plants that are hardy to F to be save. This past winter we had some hot spells in the middle of winter and very cold spells in early spring, a bad combination.
The warm spells can cause the flower buds to break dormancy, and the cold spells can kill any flower buds that are breaking dormancy. If a bud opens enough so that you can see color, it can be destroyed by freezing conditions. A spring drought can cause a rhododendron to stay dormant to conserve moisture and basically abort blooming.
Drought also causes some branches to die back, reducing bloom. Deer love rhododendron buds. Rabbits and squirrels are often reported to dine on rhododendron flower buds.
This varies considerably from region to region depending upon what food sources are available. Akamainegrower, I've actually only fertilized twice since we've lived here in six years, so that probably isn't the cause Of note, azaleas won't grow at all on my property.
I believe rhodies and azalea like the same conditions. Perhaps it's worth a soul check? In years past, when my mom owned the house, the rhodies bloomed like crazy. She said she did nothing at all with them. I'm thinking they maybe just don't get enough sun with the trees over head. But perhaps the soil has excess nitrogen. Is there something I can add to counter that? Thanks for your help!
Unless you are applying it, soils never have excess nitrogen :- Shade can certainly have an impact on flower production - all flowering plants need some sunlight to flower well.
Inadequate watering during this time period is often the cause for the buds not to form properly so lack of flowers the following season. Would also like to know why and when you prune these. You may be cutting off any potential flowers if done at the wrong time of year.
Rhodies generally need little to no pruning unless grossly overgrown or very leggy. Stop that ;0 I'm not sure how you could prune rhododendrons that regularly and have any remaining flower buds. As gardengal has pointed out, flower buds for the following Spring are set late summer. Leave them alone this year other than providing water when we've had no rain - I suspect you will have flowers next Spring. Three years seems like a lifetime, I know. What complicates the cycle and seems to drag it out is the flower buds are formed in early summer so you know by July if there will be flowers the following May.
Or at least, you'll know if buds have formed. If they form, chances are good they will open. They are not as sensitive to chilly spring temperatures as some other flowering shrubs and trees. My guess is the rhododendron in question is the large-leafed type as this is the one that balks at transplanting and other conditions found in many of our Michigan gardens. The PJM type and other types of this large family are more adaptable to the conditions we encounter in Michigan.
So all I can offer is be patient for the flowering to begin - as it relates to transplanting. Most shrubs should be fertilized once a year. Home Decor. Holiday Decor. Christmas Trees.

Hi Ka12 I talked to the painter next door yesterday and he had no idea why the formula was on on the can so I called Sherwin Williams this morning and he looked up the paint and said for you to call your Sherwin Williams in your area and give them this order number They will look it up and make it. I had several browns before I chose but had to much red in the paint so I searched and searched and came up with Bronze tone less red in it.
Good luck with your paint job when it happens , hope you show it on here would love to see it. Keep in touch I love the areas 2 hours north of me, was going to build up in St. World of golf was one place we were going but decided Orlando Airport is closer for our kids.

If you actually are in Louisiana, I believe you should add some evergreen rhododendrons and evergreen camellias, placed alternately, across the front of the house. The rhododendrons will bloom in the late spring, and the camellias will bloom October through December, depending on the variety you choose.
Blooming Evergreen Design Plant Q. You may want to consider some evergreen magnolia's; there are quite a few to choose from, popular in the Seattle area, available in fairly large sizes, have nice blooms and do well here. You may want to also consider some large rhododendron species but will have challenges finding them in a large enough size to have the impact of a tree right away and will have to wait for them to mature. There are a number of very nice deciduous trees that bloom in the winter and have winter interest but do loose their leaves.
Only one bush produces flowers, although they all bud as Only one bush produces flowers, although they all bud as though they are trying to produce flowers. Someone told me to fertilize them and put compost around them, so I did that last fall, and still nothing this spring. Any thoughts? A: The usual suspects when rhododendrons fail to bloom are dense shade, drought or overfertilization.
