I planted this popcorn viburnum bush earlier this spring. I live in zone 5. It is in a location where it receives 6-8 hours of direct sun daily. At first, it was doing quite well but lately the leaves are turning brown and crispy all along the edges as if they are burnt. I water this shrub deeply about every third day. What can I do to save this shrub?
It is possible that there are air pockets in the soil that are affecting the roots. I would step firmly on the root balls to help collapse any air pockets. Flood the area with water to help fill them in. Up its watering as well. It may also have a fungus disease, so I would treat the plant with a fungicide.
My viburnum bushes appear to be dying. The leaves are turning red to brown and some branches are already dead.
The browning could be from unsual temperature changes or a fungus. Cut out the dead, brown foliage and treat it with a fungicide, like neem oil.
I have a Viburnum "Blue Muffin, now 10 years old. Plant is healthy, bushy, vigorous and entirely lovely except. . . . . !!!! Something eats the buds as soon as they are formed. It eats only the buds (not any leaves), and no other plants nearby (roses, camellias, daylilies, daffodils, crape myrtle, forsythia, virginia sweetspire) are affected at all. We are in a gated community in the downtown area. We have rabbits, foxes, and an occasional coyote, but no deer. Any ideas
Put soap flakes around the plant and buds to keep the pests away. You can also try a pesticide. If you are sure there is not a problem with pests, a more radical but effective solution is putting animal blood around the plant, which will scare off many animals trying to eat it. If you are not into the whole blood idea, you can also try putting poison on the buds and over a couple generations, the predators will become ill when eating your plant and they will move on to something else (hopefully not your roses or forsythias haha).
Cheers,

I have a bush. It has little white lilacs. I think they're lilacs, as it has the shape of lilacs. It's blooming now, and then in the fall it gets little dark red berries on it. Do you have any idea what the name of this bush is?
Maybe it's a viburnum: https://www.gardeningknowhow.com/ornamental/shrubs/viburnum/viburnum-shrub.htm
I have two viburnums which have grown to about seven feet tall, which is too big for the plot. They are healthy specimens and show full green colour all over, although production of their white flowers has been limited. What is the best way to prune this down to a suitable size and when is this best done please?
Also, I have two Red Robin Photinia which have grown to 12 feet tall. Again, they are very healthy plants and show the characteristic red foliage which turns to green. What is the best way to prune this down to a suitable size and when is this best done, please?
Thanks in advance
You can normally prune overgrown shrubs by about a third of their growth, but no more in one given year as this could cause problems. If necessary, you can take another third off the following year until you get them at a more manageable height/shape for your needs.

I have two favourite shrubs (in New Zealand), Viburnum carlessii and Viburnum burkwoodii. I planted them about 5 years ago and they seemed to thrive, putting on plenty of new growth and flowering freely. However, this season they appeared to struggle and now I am noticing quite a lot of dieback with dead branches going to the main stem. There doesn't appear to be any disease that I can see; however, some of the affected branches do have damage from our cicada, which injects its eggs into the stem and leaves quite a scar. Can you think of any other reason why these viburnums are dying back? Thanks.
They could be affected by a fungus, which could be attacking either the roots or the branches themselves. When the branches die, what does that look like? Do the leaves turn brown right off or does some other discoloration happen? Does the whole branch die at once or does it die in a certain pattern? Let us know and this will help us determine what is affecting the plants.
What type of fertilizer is best to use on my 2 summer Viburnums?
Viburnums don't require much in the way of fertilizer. That being said, if desired, you can apply a balanced, slow-release fertilizer to the shrub.
