Normal shedding usually affects the oldest foliage inside the crown while shoot tips and current growth remain green. It is less likely to be normal when new needles fade, one side deteriorates or symptoms spread rapidly.<\/p>\n<h2 class=\"wp-block-heading\">Step 2: check the root zone<\/h2>\n<ul class=\"wp-block-list\">\n<li>feel soil moisture below the surface rather than judging by the top layer;<\/li>\n<li>look for standing water and slow drainage after rain;<\/li>\n<li>check whether soil was added over the root flare;<\/li>\n<li>record excavation, paving or vehicle traffic near the tree;<\/li>\n<li>note changes in irrigation and runoff.<\/li>\n<\/ul>\n<div class=\"wp-block-group zk-inline-cta\">\n<p><strong>Is the pine changing quickly?<\/strong> Send the whole crown, one affected branch, the trunk base and the surrounding soil.<\/p>\n<div class=\"wp-block-buttons\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"#contact-modal\" data-contact-position=\"pine-yellowing-checklist\">Heal my plants<\/a><\/div>\n<\/div>\n<\/div>\n<h2 class=\"wp-block-heading\">Step 3: inspect for disease and pests<\/h2>\n<p>Needle bands, spots and black fruiting structures may indicate a needle disease. Resin, entry holes, boring dust, fallen shoots, webbing or fixed scales point towards different pest groups. Photograph these signs before pruning, washing or spraying.<\/p>\n<h2 class=\"wp-block-heading\">Step 4: do not assume a nutrient deficiency<\/h2>\n<p>Yellow foliage does not prove that fertiliser is needed. Root damage, unsuitable pH and excess salts can prevent nutrient uptake even when nutrients are present. Soil and, where useful, tissue testing should guide correction.<\/p>\n<h2 class=\"wp-block-heading\">What to do next<\/h2>\n<p>Avoid combining fungicides, insecticides and fertilisers without a working diagnosis.
