Weigela is an easy-to-care-for plant genus, which requires full sun to light shade and well-drained soil for best growth. Regular, moderate watering, keeping the soil consistently moist, is key. It also performs well in a range of temperatures, but is sensitive to severe cold and extreme heat. Common challenges include pest issues, primarily aphids and spider mites, and diseases such as leaf spot or powdery mildew. Seasonally, weigela benefits from a heavier watering regimen in summer and a protective mulch layer in winter to protect the plant's roots.
