- Critical: Cold HardinessHardy most winters but marginal in our cold pockets, so give it a protected spot and expect the odd year of winter dieback.
Planting & establishment
Water deeply every 7 to 10 days through the first 2 summers. Winter water 1 to 2×/month October to March when soil is dry and unfrozen, winter desiccation is a top killer of newly-planted trees. Year 3: taper to 2×/month in summer, then rely on natural precipitation.
