You sure can but I would wait until summer. If they are a tree Aloe no, just put into a larger new pot and put rocks on the bottom to hold the pot down, then add the plant and put more rocks spaced so soil can fall into the cracks on top of the roots and add in the rest of the soil. I do this all the time but I live in the Los Angeles Area. I even cut off the heads to restart them, setting the heads on top of a flat of soil until they root down again. The Huntington tries every thing they can to start a week dying old plant, or to regenerate new growth and new offsets. New soil in the spring will jump start them. If you are using premixed packaged cacti mix it will be too light to hold the plant in, if it is top heavy. You can do this with Echevieria as well. Do not bury tree Aloe. Norma
