Hi, I have 3 questions: I am on upper Benchmark Drive in Telluride.
1. I need to try and get a lot of grass out of a garden area. Is there a selective you could recommend for monocots that I can spray on the garden to kill at least some of the grass, but not the garden flowers?
2. I have some very large mature spruce trees that have Western Spruce Bud Worm. It is starting to kill them. Have been treating them with BT spray applications for about 3 years, but they seem the worst this year of all. Is there a treatment you would recommend for 4 large, mature Colorado Blue Spruce to kill the Spruce Bud Worm beside BT? (bacillus thuringiensis)
3. Also have mature Aspens that have tent caterpillars-which I have mostly cut out and some leaf rollers. What would you recommend to treat for them?
