🌱 How to Care for Muscadine Grape to Prevent Phylloxera?

💧 How to Water

In the first year, water deeply 2-3 times a week to establish roots. Established vines handle drought well, but a deep weekly watering in dry weather from bloom to harvest improves berry size. Use drip irrigation: wet foliage encourages fungal disease.

☀️ Lighting

🪴 Ideal Soil

Deep, well-drained sandy or loamy soil with a pH of 5.5-6.5. In heavy soil, plant on a raised row. Above pH 7 the leaves tend to yellow (iron chlorosis).
