Care Instructions
Black Hawthorn prefers full sun to partial shade and thrives in moderate temperatures. It requires regular watering, especially during dry periods, but can tolerate some drought once established. The plant does well in moderate humidity and should be protected from extreme cold.Soil
Crataegus douglasii prefers well-draining loamy soil. It can tolerate a range of soil types but thrives best in soil that retains some moisture without becoming waterlogged. Good drainage is essential to prevent root rot.Fertilizer
A balanced fertilizer with an N-P-K ratio of 10-10-10 can be applied in the spring to support growth. Fertilize once a year to provide essential nutrients, but avoid over-fertilizing as it can lead to excessive growth and weak branches.Repotting
Repotting is generally not necessary for outdoor plants, but if grown in a container, repot every 2-3 years to refresh the soil and provide more space for root growth. Choose a slightly larger pot and ensure good drainage.Propagation
Propagation can be done through seeds or cuttings. Seeds should be stratified before planting, while cuttings can be taken in late spring or early summer. Ensure the cuttings have a few leaves and are placed in a moist, well-draining medium.Pruning
Pruning is essential to maintain the shape and health of the plant. Prune in late winter or early spring before new growth begins. Remove dead or diseased branches and thin out crowded areas to improve air circulation.Toxicity
Crataegus douglasii is not known to be toxic to pets or humans. However, the thorns can cause physical injury, so handle with care.REVOLUTIONIZE YOUR PLANT CARE
