Difficulty
With a bit of knowledge and dedication, you can successfully care for Black Hawthorn, making it a rewarding choice for those seeking a moderate challenge.
Water
Black Hawthorn should be watered regularly, allowing the soil to dry out between waterings.
Soil
Black Hawthorn loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.
Lighting
To ensure optimal growth, the Black Hawthorn prefers bright indirect light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

Toxicity
Black Hawthorn is not known to cause harm to humans or pets.
Fertilizer
The Black Hawthorn is known for its slow growth and doesn't require fertilizing beyond its potting soil. Replacing the soil in its pot once a year should offer it sufficient nutrition. It's essential to remember that plants get their energy from the sun, not from fertilizers.
Growth-pattern
New growth will sprout from the top of the plant as it grows upwards.
Region of origin
Black Hawthorn’s native range is Western N. America - British Columbia to Michigan, south to California.
