🌱 How to Care for Birch to Prevent Aphids?

💧 How to Water

Water deeply once a week during the growing season, letting water soak 20-45 cm into the soil; never let the root zone dry out completely, as birches are highly sensitive to drought stress.

☀️ Lighting

Give your birch full sun (at least 6 hours of direct light daily) for the best growth and fall color, though it will tolerate light or partial shade, especially in hotter climates.

🪴 Ideal Soil

Use a well-drained, loamy soil that is slightly acidic (pH 5.0-6.5) and stays evenly moist; birches struggle in compacted, alkaline, or waterlogged ground.
