I have tall thin Junipers in my backyard. They resemble a Hollywood Juniper but I am not sure of their species. They are 25 years old and have begun to look like they are dying, the needles are turning brown and falling off. Is there anything I can do to save them?

Junipers are some of our most hardy landscape plants, but can develop problems when the weather is very hot (such as it has been this summer!) I suspect your junipers need more water. They are mature trees now,
and their root systems are probably quite extensive. Realize that they may have extended their roots outwards at least 25 feet (same as their height).So, if you have be watering only as much as usual, and these trees are
surrounded by lawn, they are probably heat stressed and need more water.
I usually recommend watering trees extra during the hot summer months, making sure to deliver the water over most of the root zone, applying the water slowly enough so that the soil is wet 12 to 18 inches deep. This deeper soil moisture will be available to the trees but not to the lawn grass, so you can be sure that the trees will be able to take it up. Soaker hoses are great for this purpose, since they emit water very slowly and the water can percolate down into the soil without running off down grade.
When junipers are stressed, they are very attractive to spidermites. You can check for spider mites by holding a white piece of paper under a branch, striking the branch sharply, and catching the "dust" onto the paper. Watch the dust a moment. If pieces of "dust" start crawling around, the tree is infested with spider mites. To control spider mites without significantly harming the beneficial mites and insects that prey on them, try spraying the trees with a sharp stream of water every few days. This, plus the extra water you will provide, will probably help the trees regain their vigor. A shot of nitrogen fertilizer over their root zone would probably help, too. Apply the fertilizer before doing the deep watering so that it reaches the deeper tree roots (and won't be "stolen" by the lawn grass).

- I am in West Valley city, and for the past 3 years my grass has looked really good, and last year, the entire front park lane died, and I now have large areas in the front yard that are dead as well. I have heard of grubs, however I have no idea how to identify what is going on with the grass or how to treat it. You can pull up larges patches of grass easily, there don't appear to be any roots in some areas and I would like my grass to be pretty again. What can you recommend?

- I live in South Jordan. 4 1/2 years ago I started watering my yard with gray water (irrigation) due to the cost of water. Since that time I have lost 6 red twig dogwoods, 7 blue arctic willows,3 spireas, a pine tree and a Japanese maple. Everything else does not look good (other trees, bushes and perennials). In the spring it all starts out green but by June everything has brown edges on yellowing leaves and the trees have several dead branches. Could the gray water be the culprit? Everything was at least 6 years old, lush, and healthy until I changed my water. I am afraid I will lose everything else this summer if I don't find a cure for this. I could you use some answers. Thank you.
- I'm getting ready to plant grass in my back yard either this fall or in the spring. I'm wondering if dwarf fescue will grow well here in Springville, or if I would be better off planting bluegrass? I had dewarf fescue in Southern California and really liked it.

- I sodded my back yard 3 years ago with RTF. It has not held up well, especially in the higher traffic areas where it is completely dead. Any suggestions?
