Afghan Pines Browning in Desert: You're Overwatering

Brown needles from inside out on 45 Afghan pines in Willow Springs, CA = classic overwatering. Symptoms mimic drought. Conifers need deep, infrequent water once established.

Correct Regimen

Check soil 3–4 inches down—water only when dry.
Then apply 1 inch (pan method).
Stop fertilizing (Miracle-Gro) in heat—salts burn roots.
Mulch 3 inches to hold moisture.

Established trees (3–4 years) have deep roots. Back off the "love"—they're tougher than you think.
