I"m surprised you have them in Indiana! I'm in West Texas and yuccas are all over the place. I would imagine at least a month for those, but that's my SENSE and not my DATA. We've been on our 20 acres for 15 years and have knocked a few over to build various things, and the only ones that resprout are those with roots still in the ground (even under a repeat car wheel in the driveway!) We do have some dead whole ones above ground that have never sprouted... So I don't have experience of re-burying them yet. I'm certain, though, that you could remove all the "beard" material and bury that without fear of them sprouting... and there's a lot of that as biomass.
Thank you for answering.
I need to update my profile. We moved to New Mexico a couple months ago.
I have a small lot with just desert weeds that have seeded here. We are taking out everything and planting fruittrees. The soil is just sand and clay, no worms at all. A neighbor told me I can’t have a compost pile unless its covered because of rats and roaches so I have been burying kitchen scraps and anything I can to enrich to soil.
It’s all different than what I was used to in Indiana.
