We have a row of Leland cypress trees used for privacy along our property line which are diseased, I think.

They have large dead patches and we've lost one already...someone called it "rust" and someone else said it was caused by "bag worms". We've had a couple years of hot/severe draught in Raleigh and I was told this contributed. Can we cut out the dead wood and possibly save these?Photos below. Any advice on what this is and how to treat would be appreciated.
Cypress trees....what is it...what can I do?

It appears you have canker disease on your trees. You can prune out dead, but be careful to clean your pruners after every cut so you do not spread the disease. It is possible to save the trees not badly damaged by the disease. I have attached a link with more information http://ugaurbanag.com/landscapealert/prevent-problems-leyland-cypress

@J. Linder...thanks so muc for this info...never heard of this disease but the photo attached to the link looks just like our trees when they started and obviously the drought contributed to their stress. I'm having someone come out immediately to trim. Thx

Good luck, Donna. Hopefully you have caught it while you can save your trees.

They are such a pretty plant but we have the same problem with them here in central Florida.

There is a fungus that produces the twig blight your trees are displaying. With the number of trees you have on your property I think you will want to get professional help to prune out diseased limbs, remove the dead plant (or pehaps more than one I see in the photograph) and start a spray program. Soil drainage, heat and air circulations problems make the plants more susceptible to disease problems. Since you are in Raleigh you might want to call Bartlett Tree Service for a professional consultation. They do excellent work taking care of such plants in our area.

I agree with Mike and Anne about getting a professional arborist. If you decide to replace them there are lots of alternatives that should not have the same problems. If you have not been to the JC Raulston Arboretum in Raliegh it's worth many visits and you may get some good ideas for trees. Best of luck.

Me too! Had - the operative word is had - a line of over a dozen Leland cypess as boundary plantings along one side. Took about 4 years for all the trees to develop issues despite my best efforts. (Virginia) Local nursery said it was probably nematodes (also following a drought period that obviously stressed the plants and may have contributed to nemotode population explosion). Have purchased nematode resistant replacement evergreens and varied the species. Have most of 2 cypress left, but the replacements seem to be doing OK.

Thanks guys...had my tree guy come over and it's bores...he took down one and pruned the rest since they are inactive right now but advised that I'd probably loose them by summer...we're thinking maybe hollys since they are pretty hardy and grow quickly. Unfortunately both our house and the neighbor's sit close to this side of the property.

That's both good and bad news, I guess, Donna. If the space is so narrow that you are likely to brush into the plants, you might want to consider "Bright 'n' Tight" cherry laurel (Prunus caroliniana Bright 'n' Tight). It will be softer than the holly and is also a fast grower.

Good idea from Douglas about the Carolina Cherry laurel.
