The buckthorns genus, part of the Rhamnaceae family, requires moderate care. It thrives in well-draining soil, prefers partial to full sunlight, and needs regular watering, with less in winter. Temperature-wise, most species tolerate a wide range, with optimal conditions between 15-30° C. Common challenges include scale insects, aphids, and powdery mildew, particularly during humid weather. Buckthorns often needs pruning in spring to maintain shape, with leaf drop common in autumn. It's also subject to seasonal growth variations, while bearing robust weather changes overall.
