Have had one of these from Yucca Doo in the ground for about 10 years. Itís generally done well. For the first time, it shot up a flower spike in early summer this year. Impressive and beautiful.
About 6 weeks ago, the sotolís spikes started turning yellow-brown. I was unclear whether the discoloration was a function of:
- insufficiently deep soil excavation/amendments (in the form of sand/gravel back at planting time) to my native Piedmont red clay soil. Possibly meaning too much moisture in the root zone.
- inadequately alkaline soil (related to the point above, since the red clay is acidic). I have since added lime around the plant base (possibly too little, too late).
- a natural phenomenon of plant die-back following blossoming (akin to what happens to Agave Americana).
The Sotol is in a fully-exposed site.
I welcome insights from xeriscape afficianados into what may have happened and what I might do. Thanks!
