I think the common consensus is no....aloes and agaves can not be propagated via leaf cuttings... You will just have to wait for pups...

When Hurrican Rita hitting us was a definite and the whole city was evacuating (for no reason at all apparently) I put my aloe (in soil) in a closed garage. That was in September 05. Oops, I sort of forgot about it -- until March of 06. I swear to you, it was pitiful. I brought it out, gave it a drink and left it alone to see if it would come back. Guess what. A year later and the thing is 16" tall with a diameter across the top of about the same, and it just finished flowering. They can withstand a LONG drought! ;0) As for soil, the stuff you have is junk by itself. It is loaded with peat which becomes hydrophobic when left to dry between waterings. I would only use it for about a quarter of my mix. Get some landscapers mix which is pine bark well decomposed (but still piecy, if that makes sense), and some grit of some kind. I use this stuff called OilDri which I get from Sam's for about $4.84 for a 25# bag. It is med-high fired clay and will hold it's structure for up to a year or more (that I know of). I also use decomposed granite or chicken grit. The feed stores sale it as Chicken Grit, but Home Depot sales decomposed granite as well - I think it was $3 something for a pretty good sized bag. You can also use unpainted fish tank gravel. I personally am getting ready to repot all of mine again without any peat. I am using coir instead. I bought it in the form of Bed a Beast at Petsmart in the lizard/iguana section for $5.99 for a block when hydrated makes 7 liters. I am going to mix 1 part coir, 1 part landscapers mix, 1 part OilDri, and 1 part decomposed granite. This makes it about 50% grit and very free draining-- good for where I am as constant rain is a high probability during the summer. I don't like perlite as it floats to the top. A lot of people like it because it is lighter than the stuff I've listed above, but other than my huge aloe and stuff in situ, my pots are only 3" to 8" so it's a non-issue. If your roots aren't white that is okay. A lot of succulents' roots turn a reddish tan color as they mature. As long as they are not mushy and/or dark brown, you should be good to go. Don't wait too long to pot up though. It can handle it, but why stress it. Happy gardening.

I have two aloes (an A. vera and an A. saponaria) which I acquired when I lived in Arizona, and now have in Minnesota. Both flowered endlessly in Arizona, but have not yet here. They both produce pups fairly freely, but I've been trying to analyze the flowering issue. First, aloes are winter bloomers in the desert. I can't say from experience what they do in native habitat in Africa, but in Phoenix they flower from roughly December to March, when the temperature range is 30s or 40s to 60s or 70s. You might say, if the're inside during the winter in a colder climate, it's in the 60s or 70s, so why don't they flower? It presumably has to do with light levels, which are still high in the desert in winter but really low in zones 6 and colder at that time of year. It may also be that the trajectory of temperatures is necessary for flowering. Another issue is, as some others have noted, it is tricky to get an aloe used to sun again after being inside during the winter. I have to endlessly move around my winter-growing plants in early summer to get them acclimated without being sunburned. This year we had a late spring up north, and my aloes are still not up to full sun yet. I have the feeling that by the time I get them worked up to sun, there's not enough time left in the summer, or not enough light overall. Maybe some of our southern plains folks can give more information about how they work aloes up to sun again and then flower. My Haworthias and Gasterias bloom no problem, but in three years I haven't had an aloe flower yet. This is why I think the advice from Californians is not wrong, but not particularly relevant to regions where plants have to go in for the winter. I think they if they are winter growers, they get set waaaaay back by being inside for the winter, even if they are under lights (as mine are). This issue just doesn't exist in the desert, as I have learned moving from AZ to MN. By the way, Aloe vera produced pups like crazy. It is quite possible that they make so many you can't give them all away; I eventually told myself that I can't keep every baby, and some have to go in the compost pile.

Below is a link (hope it works) to my aloe vera - or just a very small section of it in my garden. Countless pups have been removed to give to other people who ask for it. If you decide to take it internally, start off with very small dosages, and gradually work your way up to the recommended dosage. However, see the warning below about internal use. When it says 'powerful laxative and purgative' it REALLY means it! Definitely do NOT administer to children. Medicinal Uses: The sap from inside the leaves can be applied directly to ulcers, burns, sunburn, radiation burns, skin cancers, wounds, poison ivy stings, acne, oily skin and dandruff, and fungal infections. It aids in healing wounds by drawing out infection and by preventing infection from starting. The fresh gel is best to use, rather than Âstabilised gels found in the stores. Internally it is sometimes used as a laxative and a general tonic. It is also to treat amenorrhoea, asthma, inflamed or diseased breasts, bursitis, colds, colic, conjunctivitis, constipation, coughs, dysmenorrhoea, dysentery with bloody stools, ear infections, eye problems, fat and sugar metabolism, fever, gonorrhoea, heart pain, haemorrhoids, hepatitis, herpes, infant pneumonia, insomnia, intestinal worms, jaundice, kidney disorders, enlarged liver, menopause, rheumatism, skin inflammations, skin rashes, sores, sore throat, enlarged spleen, toothache, tuberculosis and other lung diseases, tumors, ulcers, chronic vaginitis, venereal diseases. See Warning. Other Uses: The gel is used as a tree wound dressing. Mix the juice of 1 leaf with about 600ml water for a healthy plant spray. So it's not called the First Aid Plant for nothing! Warning: It is not advised to take Aloe Vera internally, especially if pregnant or breast-feeding, when menstruating, or if suffering from haemorrhoids or Irritable Bowel Syndrome. It is a powerful laxative and purgative. Here is a link that might be useful:
