Weeping Willow tree dying??

Can you recommend to me an arbor specialist in the Arvada Co area that I can have look at my sick tree?
I need to see if I can save it and would appreciate help if you know of someone. I looked in the phone book but that does not tell me who is a specialist. I don't want a tree trimmer but a person that can diagnose.
Thank you!

Seeding a lawn

My family purchased a new construction home in Pueblo West near the reservoir. We have an acre of land and would like to have some grass. A friend suggested we plant clover for drought resistance and low maintenance purposes. I have a few questions about this: 1) Is clover suitable for this type of area. 2) We are not able to hire a lawn company because of COVID 19 issues. Would we be able to do this ourselves? Where would we come up with top soil, how would we spread it, and is that even necessary? (I assume it is). Also, what is the best way to apply seed and how would we go about doing that ourselves?

too late for a pre-emergent?

Hi, I'm located in Colorado Springs and we've had some warm days this week. It will be in 50-60 degrees in the next few days and followed by low temps and snow. I've read that applying a pre-emergent can occur mid-March to early April. I missed the mid-March time frame.

Is it too late to apply a pre-emergent?

Why Are There So Many Pine Cones This Year?

I think we mostly have Ponderosa pines here in Larkspur. We are having a ridiculous bumper crop of pine cones this year. We are all wondering what causes it? Obviously weather, but what kind of weather? Thanks!
