ðą How to Care for Henna to Prevent Xanthomonas?
ð§ How to Water
Water every 10â14 days in spring and summer, allowing the substrate to dry out almost completely between waterings. In winter, reduce the frequency to once every 3â4 weeks. Henna is very drought-tolerant once established; overwatering can cause root rot. Always ensure the pot or soil has good drainage.
âïļ Lighting
It needs full sun, at least 6â8 hours of direct sunlight daily. Indoors, place it next to the brightest south- or west-oriented window. A lack of direct light causes leggy growth, small leaves, and low production of henna pigment. It does not tolerate shade.
ðŠī Ideal Soil
Use a substrate with excellent drainage: mix garden soil with coarse sand or perlite (1:1 ratio). It tolerates sandy, loamy, and even clay soils as long as they drain well. The optimal pH range is 5.0 to 7.0. Avoid compact soils or those with high moisture retention.
