The name Crataegus columbiana is a source of considerable confusion. The species named by Thomas J. Howell is now considered to be the same as C. douglasii, named earlier, and the earlier name should be used instead. However, some varieties of C. columbiana have also been named that are not related to C. douglasii. C. columbiana has been used by some authors for Crataegus piperi Britton, which is now known as C. chrysocarpa var. piperi.For C. columbiana var. chrysocarpa (Ashe) Dorn see C. chrysocarpa Ashe. For C. columbiana var. piperi (Britton) Eggl. see C. chrysocarpa var. piperi (Britton) Kruschke. For C. columbiana var. occidentalis (Britton) Dorn see C. succulenta Schrad. ex. Link (including C. macracantha var. occidentalis (Britton) Eggl.).
Black hawthorn is highly resistant to disease and typically does not suffer from illnesses. Regarding maintenance, this species is fairly easy to care for. When grown outdoors it needs only occasional watering, and larger specimens generally do not require pruning. Smaller specimens, however, should be trimmed after they finish flowering. Black hawthorn is well suited to anyone who has an outdoor area, such as a garden or a deck, and it does not demand much prior gardening experience.
How to keep Crataegus Columbiana.
Light
Black hawthorn grows best when it gets plenty of light for most of the day, though it can also tolerate shadier spots. Increased light supports its health and growth. In its native habitat it occurs in well-lit areas. Both too much light and too little light can be damaging to the plant.
Temperature
The black hawthorn originates from regions with a temperate climate. It thrives at temperatures between 32 and 95 ℉ (0 to 35 ℃). In warmer seasons, the plant should be kept in a shaded area to avoid exposure to direct sunlight. In colder seasons, it is advised to provide adequate protection to help the plant acclimate to lower temperatures.
Fertilizer
The Black hawthorn needs adequate nutrients for the best fruit production. Fertilize in early spring to promote new growth and flower development. Regular fertilization keeps the plant healthy, produces more flavorful fruit, and prevents nutrient-deficiency problems like yellow leaves and poor fruit yield.
Pot & Repot
When repotting Black hawthorn, choose a pot 1–2 inches (2.5–5.1 cm) larger with ample drainage. Use a well-draining potting mix. Repot in spring or fall, making sure the root ball sits slightly below the rim of the flower pot. Water thoroughly after repotting and place it in a warm spot with indirect sunlight.
