Planting & establishment
Water deeply every 7 to 10 days through the first 2 summers (less for xeric pines in heavy clay, they're prone to root rot). Winter water 1 to 2×/month October to March when soil is dry and unfrozen, evergreens transpire year-round. Year 3: taper to twice per month in summer; only during extreme drought thereafter.
