I have not had this sort of problem with either of these species, no mater how much I water them... but not grown either in that low a USDA zone (I live in one that low now, but don't have any aloes anymore). I know some aloes are prone to rot if you water their crowns, so I would avoid doing so in your climate... just water the soil (be sure super well draining) and you should have no more problems. cut off all bad tissue (I use Daconil then) and you should be OK. Be sure these plants are in full sun (both are full sun species).

Thank you . I usually use draconil, but I am either out of it or I just can't find it but I did grab some copper fungicide when cleaning out my in laws house.

I will move their little pots out into more sunlight. The sun is actually doing that by itself as it gets lower. I am always apprehensive about putting tiny pots out in the Texas Summer sun. 105 at times this week.
