🌱 How to Care for American gooseberry to Prevent Anthracnose?

💧 How to Water

Water about once a week, more often in hot weather, to keep the soil moist but not waterlogged. The roots are shallow, so mulch and drip irrigation help. Drought in summer drops leaves and buds that will not regrow that season.

☀️ Lighting

Full sun to part shade. Where summers are hot, afternoon shade keeps the leaves from scorching. More sun means more fruit.

🪴 Ideal Soil

Loam rich in organic matter that holds moisture but drains well, pH 6.0 to 7.0. Dig compost into clay soils before planting.
