🌱 How to Care for Siberian squill to Prevent Fungus Gnats?

💧 How to Water

During the active growth and flowering period (early spring), keep the soil slightly moist but avoid standing water—overwatering can lead to bulb and root rot, to which the plant is particularly sensitive. During summer dormancy, after the foliage has withered, practically no watering is needed as natural precipitation is sufficient.

☀️ Lighting

It prefers sunny or partially shaded locations; it also thrives under deciduous trees and shrubs since it receives the necessary light in early spring before the canopy fills out.

🪴 Ideal Soil

Requires well-draining, moderately nutrient-rich soil; it survives in almost any soil type (loam, sand, chalky) as long as it does not remain permanently waterlogged. Neutral, slightly acidic, or alkaline pH levels are all suitable.
