🌱 How to Care for Red Raspberry to Prevent Leaf Curl Virus?

💧 How to Water

Water deeply once a week, providing about 1–1.5 inches (2.5–4 cm) of water during active growth and fruiting. Use drip irrigation when possible to keep foliage dry and prevent fungal disease. Reduce watering in winter when the plant is dormant.

☀️ Lighting

Plant in a location that receives at least 6–8 hours of direct sunlight per day. Full sun is essential for fruit production and to minimise fungal disease risk. Light afternoon shade is acceptable in very hot climates.

🪴 Ideal Soil

Plant in fertile, well-drained soil with a pH between 5.8 and 6.8. Amend with compost before planting. Raised beds are recommended in areas with heavy or poorly drained soils. Avoid waterlogged conditions, which cause root rot.
