Greasewood Cuttings: Should I start over?

Hey everyone,

Around a month ago I went up to a friend's house in Grand Junction, CO, and found a ton of very interesting plant species. Some of these abundant species on their land were Saltbushes and Greasewood, which I took some cuttings of to hopefully propagate when I got back home. After the trip ended and I returned back, I placed these cuttings in a sterile media of just moist coconut coir, and let them do their thing. They stayed green for quite a bit, but when I checked them for any root development, their foliage turned brown, and the buried stem became discolored and mushy, consistent with rot. Is there any hope for these making a comeback? I notice a trend between me checking cuttings and them failing, is this something I should avoid entirely? If these are not salvageable, I could try contacting my friend about shipping some fresher cuttings, so there are not too many worries.

Thanks!

I have never used that method for propagating cuttings.

I like to put cuttings in water to get their roots started.

Some of those look that there maybe some life left in them, so any with green might still take root if you place them in water.

Try layering. Put a rock on a bend down branch.
Taking cuttings means cracking the code. Very complicated sometimes especially for plants not easily rooting.
Should it be green wood/ brown wood, kept in shade/ half shade, what moisture content , what medium. Try different things.
