🌱 How to Care for Caucasian Wingnut to Prevent Aphids?

💧 How to Water

During the first year after planting, water regularly, especially during dry summer periods, keeping the soil constantly moist without excess standing water. Thick mulching at the base of the tree helps retain soil moisture. Once established (from the 2nd–3rd year), the Wingnut tolerates temporary droughts well and does not require additional watering except during prolonged heatwaves. It particularly appreciates locations near a water source.

☀️ Lighting

The Caucasian Wingnut requires full sun exposure to develop properly. It slightly tolerates partial shade, but its habit will be less dense and its growth slowed. Prefer a south or west orientation, sheltered from prevailing winds. Avoid permanent shade areas that hinder its vigor.

🪴 Ideal Soil

This large tree thrives in deep, cool, organic-rich, and well-drained soil, ideally along a watercourse or near a high water table. It accepts clay, loamy, or sandy soils as long as they remain sufficiently moist. Its optimal pH is between 5.5 and 7.5. It resists temporary waterlogging well and can even tolerate short floods.
