🌱 How to Care for Perennial Lupine to Prevent Grey Mould?

💧 How to Water

Water deeply every 3 to 5 days, ensuring the soil remains cool and moist but never waterlogged. Lupine is particularly sensitive to overwatering, which quickly leads to root rot. During hot periods, monitor soil moisture more frequently. Avoid watering the foliage to limit the risk of fungal diseases.

☀️ Lighting

Perennial lupine thrives in full sun, with at least 6 hours of direct sunlight per day. It tolerates light partial shade, but flowering will be less abundant. In regions with hot summers, light afternoon shade can protect the plant from leaf scorch and prolong flowering.

🪴 Ideal Soil

Plant lupine in loamy, well-drained soil rich in organic matter. The ideal pH is between 6.0 and 7.5. Amend the soil with compost or well-rotted manure before planting. Avoid heavy, clayey soils that retain water. Lupine is a legume that fixes atmospheric nitrogen and naturally improves soil fertility.
