🌱 How to Care for Dawn Redwood to Prevent Aphids?

💧 How to Water

Water regularly during spring and summer, keeping the soil uniformly moist. Young trees need more frequent watering; mature specimens tolerate short periods of drought. Significantly reduce watering in winter during dormancy. Avoid persistent waterlogging of the roots, as it can promote rot. Mulching around the base helps retain moisture and regulate soil temperature.

☀️ Lighting

Requires full sun exposure—at least 6 hours of direct sunlight per day. In climates with very hot and dry summers, it appreciates some shade during the hottest hours of the day. It does not tolerate permanent shade, which results in weak growth and a sparse canopy.

🪴 Ideal Soil

Prefers loamy soils rich in organic matter, slightly acidic to neutral (pH 5.5–7.5). Tolerates clay, sand, and temporarily flooded soils. Avoid highly alkaline or compacted soils. Incorporate organic compost at the time of planting to improve moisture retention and soil structure.
