Nerine flowers, native to South Africa, thrive in well-drained, rocky soils and arid climates. Their bulbs are adapted to store water efficiently, allowing them to survive periods of drought. Overwatering disrupts this natural adaptation, leading to root rot and fungal infections. To mimic their natural environment, ensure the soil dries out between waterings.
Overwatering is one of the most common mistakes in Nerine care. Excessive moisture causes the bulbs to rot, as they cannot absorb water beyond their capacity. Symptoms of overwatering include yellowing leaves, mushy bulbs, and stunted growth. In severe cases, the plant may die. Proper drainage is critical to prevent waterlogged soil.
Nerine flowers prefer a "soak and dry" approach. Water deeply but infrequently, allowing the top 1-2 inches of soil to dry out before the next watering. During active growth (spring and summer), water once every 7-10 days. In dormancy (autumn and winter), reduce watering to once every 3-4 weeks or stop entirely if rainfall is sufficient.
Well-draining soil is essential for Nerine flowers. Use a mix of sandy loam, perlite, or gravel to improve drainage. Avoid heavy clay soils, which retain too much moisture. Plant the bulbs in raised beds or containers with drainage holes to ensure excess water escapes easily. Mulching with gravel can also help prevent water retention around the bulbs.
Underwatering is less harmful than overwatering but should still be avoided. Signs of underwatering include wilted or curled leaves and slow growth. To check soil moisture, insert a finger into the soil—if it feels dry at a depth of 1-2 inches, it’s time to water. Nerine flowers are drought-tolerant, so err on the side of caution.
Nerine flowers have distinct growth and dormancy cycles. During active growth, they require more water to support flowering and foliage development. In dormancy, reduce watering significantly to mimic their natural dry season. Overwatering during dormancy can cause bulb rot, as the plant is not actively absorbing moisture.
Water at the base of the plant to avoid wetting the foliage, which can lead to fungal diseases. Use a watering can or drip irrigation for precision. Morning watering is ideal, as it allows excess moisture to evaporate during the day. Avoid evening watering, as prolonged dampness overnight increases the risk of rot.
