Water well after planting and watch it for a week. In summer, give a deep soak once a week if less than 25 mm (1 in) of rain falls. Established trees need less, but the soil should stay evenly moist: shallow roots feel drought.

Full sun, 6 or more hours a day. In shade it grows sparse and drops its lower branches.
ðŠī Ideal Soil
Moist, well-drained, acidic to neutral soil with organic matter. Avoid compacted soil and ground that waterlogs.
