Thanks for an interesting article. Maybe you can give some advice about a yucca aloifolia. I am trying to decide what to do with my big yucca that laid down last summer. It became top heavy after splitting and growing two branches, and maybe also looking for light from under the trees. I don't know if I should try to cut it back and replant the top part in a sunnier area. I am a little scared of it. It is SO SHARP.
Same thing happened to me and it was a bugger to do anything with but I did and now it and all the little babies it had for having laid down are gone. I had no idea it would spread like that and that's why I removed it from my partially shaded yard. It really needs full sunlight for maximum performance.
It is an awesome specimen for around here, especially in bloom. You have convinced me to try to keep it -- at least for now.
I think I will try to get the grass way out from under the perimeter of the spines and mulch a little at the edges to keep from having to mow too closely to the sharp leaves. Getting the grass out will be a dangerous chore, however.
