ðą How to Care for Purple Passion Plant to Prevent Leaf Spot?
ð§ How to Water
Water when the top inch of soil feels dry, roughly once a week. Always water from the base to avoid wetting the velvety leaves, which can trap moisture and cause rot.
âïļ Lighting
Provide bright indirect light for the best purple coloration. A spot near an east-facing window is ideal. Too little light causes leaves to revert to green; direct sun can scorch them.
ðŠī Ideal Soil
Use a well-draining mix with a slightly acidic pH (6.1-6.5). A blend of potting soil, peat moss, and perlite works well.
