🌱 How to Care for Hops to Prevent Aphids?

💧 How to Water

Water the hops thoroughly once a week, equivalent to about 1 inch (2.5 cm) of water per week. Ensure the water penetrates 8–12 inches (20–30 cm) into the soil. Let the topsoil dry out slightly between waterings to avoid rot. During dry periods and during cone development (August–September), more frequent watering may be necessary. Avoid overwatering—hops are susceptible to root rot in stagnant, wet soil.

☀️ Lighting

Hops thrive best in full sun and should receive at least 6–8 hours of direct sunlight daily. A sunny, warm, and sheltered location provides the best growth and largest cone yield. The plant tolerates light shade, but this will reduce cone production. Ensure good air circulation around the plant to prevent fungal diseases.

🪴 Ideal Soil

Plant hops in deep, nutrient-rich, and well-drained soil with a pH between 6.0 and 7.5. Loam or sandy soil with plenty of added compost is ideal. Hops have deep roots and benefit from loose soil. Avoid heavy clay that retains moisture. Enrich the soil with well-rotted compost or manure at planting and add nitrogen-rich fertilizer in early spring.
