I wouldn't plant it deeper as that's just going to induce rot in the buried leaf axils, but you could stake it if you'd like. Or you could get a taller planter and still plant the aloe at the same depth into the soil but have more empty space up top and use the taller sides to help prop it up/control it, if that makes sense.

I'd probably also amend the soil to be more gritty/well draining if it's not already of that ilk (it looks a bit too brown for my liking; I like a healthy amount of perlite and lava rock mixed in).

Thanks! Yeah that makes sense, I'll see what I can do to keep it upright without burying it deeper. I agree on the soil, unfortunately purchased before I found this forum haha. Drains surprisingly well for what it is, but I do plan to replace it when I repot.
