I have had my holly bushes for 6 years with not a problem, beautiful and plenty of berries, but now the the leaves are dry and curling and falling off. I don't see any black spots. Is it due to the lack of snow? What do I do to save them? The bottom of the bushes are green. Thank you, bon
They may have suffered a bit of burn from the winter and yes, a lack of snow makes them more susceptible to it. It would be caused by cold winds and bright winter sun drying out the leaves. Snow helps to protect and insulate the leaves normally and a plant that has never gone through a winter without snow would be less prepared to deal with these conditions without their winter blanket. Normally, they will recover without you doing anything. They will just look a little bald for a bit. Some fertilizer may help speed the process along.
I would also treat the plant with a fungicide as a precaution as this kind of leaf loss can also be caused by a fungus.
Oregon Grape Holly has taken over the landscaping on the side of my house. What is the best way to eradicate it?
Usually keeping the plant sheared helps to keep it in bounds and under control. However, if you want to get rid of the plant altogether, you can pull it up and treat the area with Roundup (provided there are no other plants in the vicinity).
How long will it take to grow branches and leaf back up?
It will likely not survive well if you do this. Hollies can only be pruned back by about 1/3 per year - any more than this and you risk putting the plant in shock and killing it.
Whether it would grow back if it survived would depend on the variety and the health of the lower branches.
I want to know what time of year holly bushes put on berries. Mine flowered a few weeks ago and now have green berries. I am afraid this might be a sign that they are dying, as the leaves seem to be getting pale.
Generally, you will begin seeing holly berries in fall and winter months.
The leaves on my Holly bushes have turned brown on one bush and the other bush is starting to turn brown. Have the bushes died or is there something that I can do?
There are a few things that can cause this, with holly scorch being the most common. This usually happens when the weather changes too quickly. The plant will normally recover from this on its own.
What is causing holly shrubs to drop green leaves on one side?
There are many things that could be causing this.
If the side that is dropping is facing a structure, then it may be too little light.
If the side that is dropping is facing out (while the healthy side faces a structure) it may be wind or winter burn, where the wind or cold dries the leaves out causing them to fall. The side facing inward would be protected.
It may be a fungus. Typically, you would see black or yellow spots on the leaves if it was a fungus. A fungicide will help clear it up.
My holly tree has what looks like mud on many of the leaves. On the back of the leaves are white rectangular things, which look like a broken piece of spaghetti--possibly 1/8 in wide and about 1 inch long. What is this? What should I do about it?
It is possible that it is scale or mealybugs. I like to treat both with neem oil. It is very effective and safe. These articles will help:
