Alder buckthorns is a group of deciduous or evergreen shrubs, noted for their hardiness and modest care requirements. Basic care needs include well-drained soil, full sunlight to partial shade, consistent watering, and average temperatures. Common challenges faced include pests like aphids, diseases like leaf spots and root rot, and sensitivity to overly wet conditions. Seasonally, alder buckthorns may need moderate pruning in late winter or early spring while summer can necessitate supplemental watering during dry periods, and fallen leaves should be cleared in autumn to avoid disease build-up.
