ðą How to Care for Wood Cow-wheat to Prevent Aphids?
ð§ How to Water
Water only during prolonged dry spells, mimicking the moist but well-drained conditions of its woodland habitat. Approximately once per week in dry summers; otherwise rely on rainfall. Overwatering causes root rot. The hemiparasitic connection to host roots also provides some moisture supply.
âïļ Lighting
Thrives in partial shade to dappled light â the kind of light found at woodland edges or under an open canopy (approximately 5,000â30,000 lux). Avoid deep shade (below 3,000 lux) which suppresses flowering, and avoid full midday sun which scorches the delicate foliage.
ðŠī Ideal Soil
Requires moist, humus-rich, slightly acidic loamy soil with pH 5.5â6.5. Good drainage is essential; the plant does not tolerate waterlogged conditions despite needing consistent moisture. Mix in leaf mould or composted bark to replicate its woodland floor substrate. Do not add fertiliser â nutrient-poor conditions are important for successful parasitic establishment.
