Nerine plants, native to South Africa, thrive in well-drained, rocky soils and seasonal rainfall. Their bulbs store water efficiently, making them drought-tolerant. Overwatering disrupts their natural growth cycle, leading to root rot. Mimicking their native environment—dry spells followed by controlled moisture—is key to healthy growth.
From a plant’s perspective, overwatering suffocates roots by depriving them of oxygen. Nerines signal distress through: - Yellowing or limp leaves. - Soft, mushy bulbs (a sign of rot). - Stunted growth or failure to bloom. These symptoms indicate the roots are drowning, unable to absorb nutrients or breathe.
Nerines prefer a "soak and dry" approach: - Active Growth Phase (Spring/Summer): Water sparingly when the top 1-2 inches of soil are dry. Ensure pots have drainage holes. - Dormancy (Winter): Reduce watering significantly. Bulbs rest during this period and excess moisture risks rot. - Post-Flowering: Gradually decrease water to mimic natural dry seasons.
Roots need air as much as water. Nerines demand: - Gritty Mix: Combine loam, sand, and perlite (e.g., 2:1:1 ratio) for fast drainage. - Pot Choice: Terracotta pots wick away moisture better than plastic. - Elevation: Plant bulbs slightly above soil level to prevent water pooling at the base.
Nerines adapt to seasons: - Spring: Increase water as new growth appears, but let soil dry between sessions. - Autumn: Reduce watering post-bloom to prepare for dormancy. - Summer/Winter: Water minimally—only to prevent complete desiccation in extreme heat.
If root rot is suspected: - Stop Watering: Let soil dry completely. - Trim Damaged Roots: Use sterile tools to remove black/mushy roots. - Repot: Replace soggy soil with fresh, dry mix and monitor recovery.
