Older needles inside the crown commonly yellow and fall while the shoot tips remain green and continue to grow. A uniform seasonal pattern on older foliage is usually less concerning than rapid yellowing of new growth or an entire crown sector.<\/p>\n<h2 class=\"wp-block-heading\">Common causes of abnormal yellowing<\/h2>\n<h3 class=\"wp-block-heading\">Water and root-zone stress<\/h3>\n<p>Drought, waterlogging, compacted soil, added fill and damaged roots can all reduce water supply to the crown. Frequent irrigation does not guarantee that roots are functioning well.<\/p>\n<h3 class=\"wp-block-heading\">Planting and transplant stress<\/h3>\n<p>A tree planted too deeply, moved during unsuitable weather or allowed to dry before establishment may decline gradually. The root flare and soil moisture should be checked before fertiliser is added.<\/p>\n<h3 class=\"wp-block-heading\">Needle and shoot diseases<\/h3>\n<p>Dothistroma needle blight, needle cast, rust and shoot diseases may create bands, spots, black fruiting structures or a characteristic distribution within the crown.<\/p>\n<h3 class=\"wp-block-heading\">Pests<\/h3>\n<p>Mites, scale insects, sawflies and bark beetles can change needle colour, but each leaves additional evidence. Holes, boring dust, resin, webbing and damaged shoots should be documented.<\/p>\n<div class=\"wp-block-group zk-inline-cta\">\n<p><strong>Is yellowing spreading or affecting new growth?<\/strong> Send the whole pine, an 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-causes\">Heal my plants<\/a><\/div>\n<\/div>\n<\/div>\n<h2 class=\"wp-block-heading\">What to check before treatment<\/h2>\n<ul class=\"wp-block-list\">\n<li>which needle age is affected;<\/li>\n<li>whether yellowing is uniform or confined to one side;<\/li>\n<li>soil moisture below the surface and drainage after rain;<\/li>\n<li>recent excavation, paving, soil addition or irrigation changes;<\/li>\n<li>spots, bands, resin, holes and insects;<\/li>\n<li>whether neighbouring pines show the same pattern.<\/li>\n<\/ul>\n<p>Do not apply fertiliser simply because needles are yellow: excess salts can worsen root stress.
