ðą How to Care for Japanese Yew to Prevent Mealybugs?
ð§ How to Water
Water deeply and regularly during the first growing season to help roots establish, keeping the soil moist but never soggy. Once established, Japanese yew is fairly drought tolerant and only needs supplemental water during extended dry spells - overwatering and poor drainage are the leading causes of root rot in this species.
âïļ Lighting
Japanese yew thrives in full sun to partial shade and is one of the most shade-tolerant needled evergreens available, though a few hours of daily sun keeps the foliage denser and richer green. Protect it from harsh winter wind and sun exposure, which can cause winter burn on exposed foliage.
ðŠī Ideal Soil
Plant in sandy or loamy soil that is acidic to neutral (pH about 5.0-7.5) with excellent drainage. This species has almost no tolerance for wet, compacted, or poorly drained soil, which quickly leads to root rot.
