ðą How to Care for Muscadine Grape to Prevent Thrips?
ð§ 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.
âïļ Lighting
Needs at least 6-8 hours of direct sun a day to fruit well. It tolerates partial shade, but then grows more leaves and less fruit.
ðŠī 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).
