🌱 How to Care for Freesia to Prevent Thrips?
💧 How to Water
Keep the soil evenly moist during the growth and flowering period, but allow the top layer to dry out slightly between waterings—stagnant moisture causes corm rot. Gradually stop watering after the flowering period ends.
☀️ Lighting
Requires plenty of light: a sunny but sheltered spot outdoors, or bright, indirect light indoors. Avoid harsh midday sun to ensure the blooms last longer.
🪴 Ideal Soil
Requires loose, well-aerated, nutrient-rich soil—mix sand or perlite into the earth to ensure good drainage; soil pH should be neutral (6.0-7.0).
