info
Water this plant regularly, when the top inch or so of soil feels dry. If you establish this pattern over several years, then you can cut back to watering every week or two in dry weather. Use drippers, emitters, or a slow stream of water so that it does not run off; allow the water to trickle all the way down through the deepest layers of soil. In a pot slowly water the entire surface until water comes out of the bottom of your pot.

This plant has adapted to survive drought by shedding its leaves, and as such if it defoliates during a dry spell you’ve probably pushed it too far. It’s not dead though! Give it a good deep watering and it should come back.
