Uniform loss of the oldest generation with living buds can be natural. Dieback of the leader, one large branch or a defined side of the crown points toward a local factor such as root injury, altered water movement, a wound or a disease focus.<\/p>\n<p>View the tree from a distance and then close up. The overall view shows symmetry; close photographs reveal spots, bands and bud injury. Do not remove all affected shoots before documenting their position.<\/p>\n<h2>A short sign map<\/h2>\n<figure class=\"wp-block-table\">\n<table>\n<thead>\n<tr>\n<th>What you see<\/th>\n<th>What to check<\/th>\n<th>Why it matters<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Old inner needles yellow<\/td>\n<td>Current shoots and buds<\/td>\n<td>May fit natural shedding<\/td>\n<\/tr>\n<tr>\n<td>One crown side declines<\/td>\n<td>Trenching, paving or compaction there<\/td>\n<td>May indicate local root impact<\/td>\n<\/tr>\n<tr>\n<td>Shoot tips turn brown<\/td>\n<td>Buds, live-tissue boundary and resin<\/td>\n<td>Not the usual old-needle pattern<\/td>\n<\/tr>\n<tr>\n<td>Holes or boring dust appear<\/td>\n<td>The entire trunk and major branches<\/td>\n<td>One sign does not identify the insect<\/td>\n<\/tr>\n<tr>\n<td>Trunk base is wet or buried<\/td>\n<td>Root flare, irrigation and drainage<\/td>\n<td>Root-zone stress appears in the crown<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n<h2>Why soil moisture cannot be judged from the surface<\/h2>\n<p>A wet surface does not prove that water reached active roots evenly. Turf may be damp after frequent shallow irrigation while soil below remains dry. In heavy compacted soil, retained water can instead displace oxygen.<\/p>\n<p>Check several points under the crown and consider slope, downpipes, irrigation and new paving. Record when conditions changed because needle response may lag behind the initiating event.<\/p>\n<h2>Photographs useful for initial assessment<\/h2>\n<ul>\n<li>the whole tree with surrounding site;<\/li>\n<li>the crown from four sides;<\/li>\n<li>the boundary between green and affected needles;<\/li>\n<li>current shoots and terminal buds;<\/li>\n<li>trunk, resin, holes and wounds;<\/li>\n<li>the trunk base and soil surface.<\/li>\n<\/ul>\n<p>Add a timeline, irrigation pattern, recent works and previous treatments.
