Crataegus submollis, known as the northern downy hawthorn, northern red haw, Quebec hawthorn, or hairy cockspurthorn, is a species of hawthorn that grows to about 7 m in height and typically carries large crops of red fruit.
The Quebec hawthorn is resistant to disease and is generally unlikely to develop illnesses. In terms of maintenance, this plant is fairly low-maintenance. When grown outdoors it needs little water, and larger plants typically do not require pruning. Smaller plants, however, should be trimmed after they finish blooming. The Quebec hawthorn is appropriate for anyone who has outdoor space, such as a garden or a deck, and it does not call for extensive care experience.
How to keep Crataegus Submollis.
Light
Quebec hawthorn is native to open habitats, such as sunny meadows and forest edges, which provide abundant light. It performs best in full sun but can also tolerate partial sun, adapting well to a range of light conditions.
Temperature
Quebec hawthorn is highly adaptable to a range of climates, from very hot summers to cold winters. Still, it has an optimal temperature range for growth. When temperatures get too high, the plant can experience heat and humidity stress that may lead to its death. In areas where temperatures near the lower limit of its cold tolerance, it is important to use insulation measures to protect the plant.
Fertilizer
The Quebec hawthorn needs adequate nutrients to achieve optimal fruit production. Apply fertilizer in early spring to encourage new growth and flower development. Regular fertilizing helps the plant stay healthy, produce more flavorful fruit, and prevents nutrient-deficiency problems like yellowing leaves and poor fruit production.
Pruning
Quebec hawthorn is known for its thorny branches and clusters of white flowers. To encourage strong growth and prevent diseases, make sure to prune the plant in early spring. Focus on removing any dead or crossing branches to improve air circulation and shape the tree. This will enhance both its health and its ornamental appeal.
Pot & Repot
For Quebec hawthorn to thrive in pots, it needs excellent drainage.
