Buckthorn is a group of evergreen shrub species with small, inconspicuous flowers. These plants grow throughout North America in moist, open areas with nutrient-rich soil. They all produce fruit that is red or black and in the shape of a drupe. There is some taxonomic contention in the scientific community surrounding this genus.
Water:
Buckthorn thrives in its natural habitat with intermittent rainfall, exhibiting moderate drought tolerance. Watering should occur every 1-2 weeks to avoid over or under-watering. It is often grown outdoors, benefiting from natural precipitation and varying moisture conditions.
Propagation:
Propagation of buckthorn involves seed sowing and softwood cuttings. Essential growth factors include adequate light, consistent moisture, and neutral pH well-draining soil. Seeds may require 2-3 months of cold stratification, while cuttings need rooting hormone. Optimal temperatures are 15-20°C for seeds and around 20°C for cuttings.
