🌱 How to Care for Ribes (genus) to Prevent Anthracnose?

💧 How to Water

Keep soil moist but never soggy: water every 5 to 7 days in warm weather, at the base and in the morning, without wetting the leaves. Young plants need regular water for their first two years; in pots, check daily in hot spells. Drought yellows the leaves and raises mildew risk; heavy watering during ripening can split the fruit.

☀️ Lighting

Full sun to part shade, with at least 6 hours of sun; afternoon shade helps in hot summers. Avoid spots exposed to cold winds and late frosts, which damage the flowers.

🪴 Ideal Soil

Rich, well-drained but moisture-retentive loam, slightly acidic (pH 5.5 to 6.8). Avoid light sandy soils that get hot and dry and heavy waterlogged clay. Keep 8-10 cm of mulch over the roots.
