🌱 How to Care for Love-Lies-Bleeding to Prevent Alternaria Leaf Spot?

💧 How to Water

Water deeply once or twice a week, letting the top few centimetres of soil dry out between waterings; increase frequency only while seedlings are germinating or the plant is flowering and setting seed, and always avoid waterlogged soil, which quickly leads to root rot.

☀️ Lighting

Give it full sun -- at least 6 hours of direct light a day -- for the strongest color and longest tassels; in very hot climates a little afternoon shade prevents scorching, but deep shade will produce weak, leggy, poorly flowering plants.

🪴 Ideal Soil

Plant in fertile, well-drained soil with a pH between 5.5 and 7.5; the species tolerates acidic to alkaline conditions but resents heavy, compacted, or waterlogged clay, where the roots are prone to rotting.
