Will killing lawn w/glyphosate also kill cottonwood?

I'm in Broomfield, CO, and am planning to kill grass and weeds (it's mostly weeds if I'm honest) in my lawn with glyphosate to plant a more waterwise grass. (Dog Tuff grass--would appreciate any reader experience with this too.)
I have a huge cottonwood (Plains cottonwood, I think) in the lawn and wonder if the glyphosate will damage the shallow root system and kill the tree. The tree has likely already been stressed by landscaping done this fall.
Thanks for your insight!!!

Maple with yellow leaves all summer

Hi,
I have a maple tree in my yard that has had yellow leaves all summer. Actually, the veins are green and the rest of the leaf is yellow. A branch or two on one side are pretty much normal, all green. Other trees in the neighborhood have the same problem. We planted our tree about 10 years ago and it has been this way for maybe the last three years. Does it need some kind of fertilizer? Or??

Water testing

Curious what test need to run to evaluate our water for the garden. The water is from a well and run through a series of filters. We noticed a white residue on the soil. This is a first summer/ year garden and soil is not immaculate. We are amending with compost. The direct question is what water test and where to send it? Thanks, Stuart

Pruning peach trees

Hello!
I have a ten-year-old Saturn peach tree and a four-year-old regular (large) peach tree. I'm wondering if you can point me in the direction of some good videos/resources to determine how and when to prune these trees.
Thank you.

correct low calcium in soil

Last spring I had a soil test performed through the extension service which indicated low lime and high PH (7.9). I have had problems with blossom end rot in tomatoes and similar problems with bell peppers this gardening season. After doing a little research I see that lime is recommended to correct these types of problems but then found some information about lime raising the soil PH. Would gypsum be better?
