🌱 How to Care for Bald Cypress to Prevent Broad Mites?

💧 How to Water

Water abundantly during the first few years of establishment, especially in summer, keeping the soil moist but not permanently waterlogged in dry areas. Mature specimens tolerate seasonal drought well. In winter, when the tree loses its leaves, reduce watering but do not let the soil dry out completely. This species also tolerates prolonged flooding and can grow with its roots submerged up to 60 cm deep.

☀️ Lighting

Plant in a full sun location, with at least 6 hours of direct sunlight per day, for the best development, vigorous growth, and characteristic reddish autumn foliage. It tolerates light partial shade, but in low-light conditions, the tree may grow more slender and less dense. Avoid completely shaded locations.

🪴 Ideal Soil

Prefers acidic to neutral soils (pH 4.5–7.0), with a sandy to loamy texture and good moisture retention. It adapts to heavy clay, sandy, compacted, and even alkaline soils, although in the latter, it may show iron chlorosis (yellow leaves). For best results, plant in acidic, cool, and slightly moist soils. Add organic matter when transplanting to improve water retention in well-draining soils.
