I love to golf. One of the reasons I love to golf is that I love the serenity of a golf course and especially the beautiful mature trees of all sorts. The Globe Willow in particular is my favorite because of its shape and size so I decided to purchase one and plant it in my backyard. I have read several articles that talk about these trees being very suceptible to disease and I wondered if it was as much of a problem here in Utah with such cold winters for half the year. I don't want to watch this tree suffer its whole life and end up taking it down. I live in the Cottonwood Heights area. Can you help with any advice?

The articles you refer to regarding globe willows high susceptibility to disease is true. However, I must first qualify that trees are susceptible to disease when stressed, usually by cultural and environmental conditions that are not ideal for growth. Willows usually grow very quickly, therefore the wood is weak and, especially with globe willows, their branch angle and attachment is weak and subject to breakage either from snow load or high winds. A common disease associated with globe willow is slime flux. This bacterial disease of trees is also known as "wet wood" disease. This disease is caused by bacteria that creates pressure and slime oozes out of cracks in the trunk and branches.
Globe willow (Salix matsudana 'Globe Navajo') in our Utah State University Extension Publication "Selecting and Planting Landscape Trees" (http://extension.usu.edu/forestry/Reading/Assets/PDFDocs/NR_FF/NR460.pdf) suggests it is a species that rarely should be planted, though limited use in specific situations may be justified.
I hope that answers your question. If you have any other questions please feel free to contact me.

- I have 2 red tipped photinas in my front yard against the house (south facing). They were great for the first 3 years, but now, for the last 2 winters the leaves have dried out and dropped in the spring. I thought it was a lack of water over the winter, so I tried to help out, but that didnt help. Should I prune them back in the fall or is there anything I can do to help them so this doesn't happen next winter?

Is there any validation to her statement?
- I have some problems with native Juniper trees dying(25 ft average height). They start turning yellow (chlorosis has been ruled out) then brown on south side first, then slowly spread to north end of plant. I have cut down one and found no signs of insect damage or disease. Only trees located next to a dirt road(South of trees) are currently affected. They started changing in color last summer. The county does spray for russian thistle on road. Yet no other trees seem to be affected. Can you provide other possible reasons or someone that may be able to come and see them (test them)?
- I mowed my lawn today (04/18/08) and noticed some dead "tracks" that I do not remember seeing when I mowed on Saturday (04/14/08). I thought that it might have been something from my lawn mower but it is a brand new Honda that I purchased 1 month ago. I have posted some pictures on my website and can be viewed at supersoygifts.com/grass.htm. Thanks for any info you can provide.
