Grasshoppers in my garden and pastures

Grasshoppers are defoliating my garden and pastures. This has been an ongoing problem on my ranch for many years. I am looking for help with long term control. I have heard about Semaspore and Nolo Bait being used for biological control, but I can't find a supplier. I also read about destroying the grasshopper's egg beds, but don't know how to identify the location of the egg beds. Any help you can supply would be appreciated!

Apple Variety

My parents on the Heart Mountain Project between Powell and Cody, Wyoming raised an orchard in the 1950s with an apple tree. Apples were crisp, tart and used mostly for pies (some applesauce, some cider). They started falling off the tree in August. I need help to identify the apple variety.

aspens dying in NE Laramie

What is the cause of aspens dying in the Alta Vista neighborhood of NE Laramie? We water our aspen and they have survived longer than many, but now the leaves are yellow,some branches are bare, and there is a fine black deposit on the ground under the trees. What can we do? If they die can we replant aspen, or will the same problem reoccur?

Rasberry (Rubus Idaeus) won't flower or produce berries.

I have raspberry bushes I planted 4 years ago. They are big healthy bushes and are sending out new bushes, but have never flowered or produced fruit. I had the soil tested and it came back with a ph of 8.2. The testing only recommended adding some fertilizer with nitrogen twice a year. What can I add to lower the soil ph? And any other suggestions would be appreciated. Thanks CL

Aspen pruning

I read in numerous places online that Aspens must be pruned when dormant. The local arborist insists he can safely do it now in August. I also have some Choke Cherry trees. What are the facts?
