AvocadosQ: Can Avocado trees be raised in containers? – Angel G.

A: Growing any type of fruit tree in a container is tough. The operative word here is “tree.” Trees generally need more root space than most containers can give them, but it can be done! I wouldn’t use a container smaller than a ½ wine barrel- a container with at least 2.5 ft width by about the same depth.

Choose a dwarf-type tree. If a fruit tree is to be kept in a container longer than a few years, it is usually only successful using a dwarf variety. ‘Wurst’ (also called ‘Little Cado’) is a dwarf variety and is sometimes recommended for container planting. This avocado is a hybrid type (a cross between Mexican and Guatemalan varieties) and it is not tolerant of temperatures below 30F.  The one advantage to a container grown plant is that you do have the option to move the container to a protected place when the temperature plummets.

You could also consider a ‘Stewart’ avocado for this climate. It is not a dwarf, but it is a smaller, compact tree and tolerates colder temperatures better than the ‘Wurst’.  I can speak from personal experience to the success of keeping a ‘Stewart’ in a container for a few years before it required root-pruning and re-potting.

Quick Facts

  • Avocados like a planting medium similar to citrus. Make sure that it is slightly acidic and drains well.
  • Don’t expose your young tree to intense sun during the summer.
  • Avocados are very sensitive to salts accumulating in the planting medium, so be sure to flush the salts from the pot periodically.
  • Do NOT over-fertilize avocados –especially when planted in containers. Watch for leaf burn, both from intense sun and over fertilization.
  • Mulch the surface of the pot to keep the shallow roots cool, while allowing air circulation.
  • Don’t expect fruit too soon after planting! It can take 5 years or more before your tree may bear fruit.
