Water:
Rubia thrives in consistent moisture, typical of temperate regions. It requires weekly watering, avoiding excessive hydration and extreme drought. Best suited outdoors, rubia benefits from natural rainfall during its active growing season when water demand is highest.
Propagation:
Propagation of rubia involves seed sowing, cuttings, and division, requiring bright indirect light, stable temperatures, and well-draining organic soil. Cuttings should be 4-6 inches, with lower leaves removed and dipped in rooting hormone, planted in peat and perlite, and kept humid until rooted.
