Step 9
Encourage natural predators by planting nectar-rich flowers (yarrow, dill, fennel) nearby
Step 10
Install bird feeders and water sources to attract insect-eating birds

ðą How to Care for American gooseberry to Prevent Caterpillars?
ð§ 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.
âïļ Lighting
Full sun to part shade. Where summers are hot, afternoon shade keeps the leaves from scorching. More sun means more fruit.
ðŠī 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.
