Why does your Taxus baccata have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Yews have relatively shallow root systems and are sensitive to drying out. When the soil becomes too dry, the plant cannot transport enough water to the distal ends of the needles, causing tip necrosis.
Excessive salts from hard water, de-icing salts, or chemical fertilizers accumulate in the needle tips. This creates osmotic pressure that dehydrates the tissue cells, leading to browning.
Waterlogged soil can lead to root rot caused by Oomycetes like Phytophthora. As the root system fails due to decay, the foliage exhibits characteristic browning starting at the tips and moving inward.
Strong, drying winds can strip moisture from the needle tips faster than the plant can replace it via transpiration. This is particularly common in exposed locations during winter or dry summer spells.
