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 (or less) in dry weather. Use drippers, emitters, or a slow stream of water so that it doesn’t 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.

Plants grown in cool coastal climates and in shade will require less water.
