Roundup Questions

Hi OSU: I have a client I'm working with who wants to saturate her hillside with roundup to help control the old english ivy that is there and then stake the area with typar landscape fabric. I'm wanting to find out if this will be a problem for the plants there. There are 2 young Maple Trees, Weeping Atlantic Cedar, and Photinia we don't want to hurt. Can you say whether or not this would hurt these other plants, and if not where I can find out before she puts down the roundup? Thanks for your time and consideration as always!

Our association of 18 units have had an exceedingly amount of damage with Moles this year. We have spent nearly $200 on poison Mole worms with mixed results. Is it because we may have excess grubs in our lawns? What results could we expect if we sprayed for grub worms? We would have to consider the cost of hiring our landscaper to do a special spraying and how it would effect our poison worms cost. Any recommendations on spray brand and an estimate opinion of success would be appreciated.

I have two maple trees in my front yard. I estimate their ages at 40-45 years. I believe they are both a type of Silver Maple and they were likely planted at the same time. They are about 15 feet apart. I've owned this property for 8 years, and for most of the time I've been here I've observed that one tree has consistently produce a more sparse leaf canopy than the other. The difference is significant in my opinion. I estimate that on average the canopy of the "healthier" tree is approximately 30% more dense than that of the tree with the thinner canopy. The thinner tree also has a lot more dead branches and twigs. As far as I can tell these trees share the same environmental/cultural factors. Both trees are in my front yard and turf grass is planted under them. Both trees receive approximately the same amount of sunlight, which in the summer amounts to 10-12 hours/day. Likewise both trees receive the same amount of water. In my 8 years here I've had the soil tested twice. Both times I applied 1 lb. nitrogen / 1000 sq. ft. of lawn as directed. In any case, both trees benefit from the same treatment. The difference in canopy of these trees has been fairly consistent over the past 6-7 years since I first noticed it. But I fear that one of these years the thinner tree to could take a turn for the worse and I'll lose it. I tried to attach two digital photographs, one of the thinner tree, and one of the thicker, but I was only able to attach one photo in this form so I attached the photo of the thinner tree. I think you can see a number of dead, leafless branches in the photo of the thinner tree. Do you have any idea why these trees produce such different canopies? Is there anything I should do to help maintain the health of these trees?

The squirrels have left broken walnut shells from our large walnut tree all over our grass. I'm concerned they will kill the grass. I'm picking up the walnuts and raking the shells, but I can't keep up. There is no way I can rake up all the tiny shell pieces. Anything else I can do to save my grass.
