Central Phoenix -- I have had mixed luck with Aloe dichotoma. I currently have 4, all planted in the ground. The tallest is 5 feet with one head. I have in the past had one large specimen killed by power company tree pruners, a small one killed by rot, and 4+ foot one killed by frost. The frost-kill occurred despite a fabric cold frame but a 2011 late freeze (early Feb.) following a warm spell gave us mid 20s F for 4 consecutive nights. Three shorter ones around it survived, including the one that is now 5 feet. My current ones winter under a 6 foot tall cold frame. They receive partial winter sun and strong afternoon summer sun. They get monthly water in summer, none in winter unless it rains.

Nieuwoudtville. Aloe dichotoma. Kokerbome.These giant aloes on the farm Gannabos 22km from Nieuwoudtville on the road to Loeriesfontein are in bud and will be in full flower within a week. This collection of giant aloes is the Southern most as well as the largest aloe forest in South Africa. There are thousands of them. These photos are just of a very small section of this giant aloe forest. Hendrik van Zijl. http//www.nieuwoudtville.co.za

My son had two beautiful aloe dichotoma trees in his front yard. One of them had developed five heads during the six years it had been happily in the ground. Imagine the frustration when he went outside and found it gone......STOLEN....... out of the yard with the empty hole to remind him of where it stood!

I got this one in a pot. Don't plant it in the ground in florida, it will rot . this one does fine in a pot in full sun, south exposure..I have never seen it for sale around here, had about 30 out of 100 seeds survive the first year with wet summer.

Good Aloe tree for the deserts of Arizona, just keep it away from excess irrigation as the roots are capable of stretching quite far and into the beds of your nearby flowers, veggies, etc. A local nursery learned that the hard way years ago when their large plant had stretched its roots under shrubs they regularly irrigated and the once beautiful specimen exists, sadly, no more. If you have a rocky slope, give this plant a try there!

A Dichotoma is a super-cool and increasingly popular aloe down here, like hens teeth only a couple of years ago and now more readily available. Thus our knowledge of long-term care is limited, but it seems to be no more demanding than the other tree aloes, in spite of it's prima donna reputation.
Like most of the tree aloes, it seems to grow relatively faster in the southern hemisphere than up north but thats probably because we a not a xeriscape situation and have higher UV levels.
I find growing these beauties 'hard' - out in fullest, harshest sun you have access to, with a limited root run- is the best way to go; they attain a more adult look, are less likely to rot out. Go for a plain terracotta pot so you know it's drying out... read more

I saw a young one in Oakland that had to have a trunk almost a foot wide on a plant only three feet or so tall! And a local nursery has one for sale about eight feet tall with a massive base, for $2,000. Hurry-ha.
EDIT: 2009. The summer of 08 I planted a nice sized gallon plant..no troubles with our bay area winters. How fast they grow will depend of course on best case conditions. Mine is in a bit more shade and with some other large succulents. 33f and our rainy winters havent bothered it.

This is one of the most striking tree Aloes. It is relatively slow to grow, but it develops a massive, tapering, smooth (up top), papery-covered trunk with several branches topped by sea blue-green leaves. Lower trunk is cracked and has very rough, sharp edges etched in it. It makes an excellent specimen tree, and is great for xeroscaping. However, if given some water in well draining sandy soil, it will do even better(grow faster and become more robust). If overwatered in the summer months, it can rot. However, it seems to tolerate our deluge of cold winter rains here in So Cal without any problems, as long as it's not planted in mud. One of the most common mistakes by those growing Aloes is not watering enough. Without enough water, the leaves curl up a bit and necrose at the tips... read more
