The answer is yes. My aunt asked me about this yesterday. Her yard space is well-spoken for, but her husband would really like to have an avocado tree. “They get big,” she said. They do indeed. Most varieties will exceed 30 feet, if unimpeded. But they don’t have to.
Here are my best two ideas for growing an avocado tree in your yard if you only have a small space — that is, if you don’t have a space that is 30 feet wide and tall.
One, plant a Hass avocado tree and keep it pruned to about 15 feet wide and tall, like this one in my yard:
This Hass tree is carrying about 150 avocados this year. Hass is the variety that you buy in grocery stores, of course. It has excellent flavor, as you know, and the fruit will hang on the tree waiting for you to pick it from about February until July (even longer sometimes). Simply prune the tree once or twice a year to keep it at a 15-foot canopy. I’ve been doing so, and I know of other Hass trees that are kept this size while still being productive as well.
Another idea is you could go with a variety called Reed, which naturally grows smaller than Hass. You can keep a Reed avocado tree pruned down to 10 feet and still get plenty of fruit. Here is my Reed tree today, at about 12 feet tall and wide, carrying around 75 avocados.
But do Reeds taste good? They certainly do — plus the fruit is bigger, and they also don’t brown when you cut them open and leave half in the fridge. (Read my post: “My Favorite Way to Eat a Reed Avocado.”) In case you haven’t seen Reed avocados, here are a few (not yet full size) hiding under the canopy of my tree.
Another productive and naturally smaller tree similar to Reed is the Lamb, also called Lamb Hass. If I couldn’t find a Reed, I’d go with Lamb. I have one that is only eight feet tall and six feet wide, but still carrying about 30 avocados. It would be easy to keep this Lamb pruned to under 10 feet tall.
But can you keep avocado trees pruned small in the long term? You certainly can. The best example I’ve ever seen of an avocado tree kept small for decades is a Fuerte in the yard of some friends who live in National City, just south of San Diego. They inherited the tree when they bought the house. A Japanese family had lived there for a long time prior, and this Fuerte tree is close to an avocado bonsai. It’s got to be at least 30 years old judging by the trunk diameter, and yet it’s been carefully pruned over the years to remain at only 10 feet tall and 20 feet wide: shaped like a saucer.
Note well that Fuerte is a vigorously growing avocado variety. In other words, if you can keep a Fuerte down to size, you can keep any variety down to size.
And most importantly, it produces lots of fruit. I counted over 100 on the day I took this photo.
Ancillary benefits of keeping an avocado tree pruned down is that you can pick most if not all of the fruit by hand (no poles or ladders), and also, small trees require less water than big trees. For more on pruning, see my post “Pruning avocado trees.”
“Dwarf” avocado varieties
How about planting one of the dwarf avocado varieties? The two widely available avocado varieties that are called dwarf are Holiday (pictured at the very top of the page) and Wertz (which is also sometimes called Wurtz, Littlecado, Minicado, or Dwarf Hybrid avocado). The advantage of these varieties is that they are naturally slower growing than others. Therefore, you won’t have to prune as much to keep one of these trees small. But that is the only advantage that I’m aware of.
There are disadvantages. The Holiday seems less productive than Hass or Reed. This has been my experience with two Holiday trees that I’ve grown in two different locations, as well as the Holiday trees in yards of friends.
As for Wertz, however, I can only give secondhand information, I’m sorry to say. I’ve never grown a Wertz nor have I tasted its fruit. What I do hear from experienced and reliable people is that Wertz fruit is good but not quite as tasty as Hass or Reed. Taste is subjective though, it’s true. And again, I can’t speak from personal experience about Wertz’s eating quality.
Anyhow, in my view, the only reason to choose Holiday or Wertz instead of Hass or Reed or Lamb would be if you wanted a small avocado tree but didn’t want to do much pruning. That’s a reasonable desire, but just be aware that you might not get as much fruit or fruit that is quite as tasty.
In the end, if you want an avocado tree in your yard and you have even a 10-foot by 10-foot patch of dirt available, it’s possible. It’s more than possible, it’s proven and it’s prescribed.
