Maintenance

Best in alkaline soils. Winter or Spring: Apply 2″ – 4″ of mulch and a thin 1″ – 2″ layer of compost over and beyond the root zone. Do not allow mulch to contact tree trunk. Foliage tips may burn in hot summers. May require extensive watering, but do not overwater. Prune only if necessary and less is better. Protect bark, add fencing for deer protection.
