You can plant it deeper, you can also cut it anywhere along the stem to take off some weight. The bottom will grow new plants from the side and the top can be rooted. Your choice, both methods work.

I would cut the tall one, let dry, and reroot it as Garrett and Nik have suggested.

Make sure you don't bury any leaves because they will rot. You also don't want the stem very long under the soil because the roots mostly tend to grow out the end and not along the stem.

I just received some aloe pups, they have a bit of root but not much on them. Should they be left out to dry until they grow more of their own roots?

Yes. I always leave aloes to dry, they are very vulnerable to stem rot.

Ok, I don't know much about aloe, so I'm confused. You say "cut and let dry". Another says "leave unpotted". I don't understand. Can you explain specifically step by step what you mean? To me, to cut and let dry, to leave unpotted would be to kill the plant. Leave unpotted, let dry.....on a table just laying there? Plz forgive my ignorance and explain. Thank you

How can they grow more roots if they are dry?

Their fat, fleshy leaves are water storage organs, they already contain the water the plant needs to get started growing.

You can leave it to dry somewhere cool and a little light. Not directly under the sun. The objective is to have it grow new roots before losing too much water (for an Aloe of this size it should not be so difficult).

Yes, cut, let callus (scab over/dry up the cut) - unpotted = out of soil. The cut will not dry up if in the soil...
