How quickly does a hawthorn tree grow?
Hawthorn hedging is a fast-growing species, putting on 40-60cm per year. This makes it an excellent choice for privacy screening, boundary planting, and wind protection. It also makes an effective intruder-proof hedge thanks to its strong framework and long, sharp thorns. Hawthorn (Crataegus) are small to medium trees many of which are suitable for exposed sites and smaller gardens. Dwarf varieties can also be grown as large shrubs in borders.The large leaves have good resistance to leaf spot. Olivia™ (‘Conia’ PP9399) is one of the most disease resistant Indian hawthorns. It grows to 4 feet tall and 4 to 5 feet wide with white flowers. Rosalinda® (‘Conda’ PP9056) is typically grown as a tree form, and reaches 10 to 12 feet tall by 8 to 10 feet wide.The large leaves have good resistance to leaf spot.

They flower and fruit reliably, with decorative haws (fruits) persisting into winter.Why it’s a problem. Common hawthorn is an introduced tree that has naturalized in the Pacific Northwest. This small tree rapidly spreads by seed into woodlands and open fields. It creates dense, thorny thickets that outcompete native species.
Does hawthorn have deep roots?
Hawthorn roots typically reach an average depth of 2-3 feet (60-90 cm), depending on the soil conditions. Their spread can extend 3-4 feet (90-120 cm) from the base of the plant, allowing for effective nutrient uptake and stability. Hawthorns thrive in climate zones 4-8 and are resilient and easy to grow. Once established these shrubs are drought and heat tolerant, thriving in shade to full sun. WINTER/SPRING: This is when suckers should be removed or transplanted if desired. Pruning should also be done while trees are dormant.However, it can easily be kept at a lower height of between 1. Hawthorn has a looser, less formal appearance when trimmed occasionally, or left untrimmed.After flowering, trim back errant branches and shape as needed. Cut out dead or diseased growth as soon as it appears. Indian hawthorn can also be kept pruned as a formal hedge, though leaves that are sheared in half may look unsightly. Larger varieties such as ‘Majestic Beauty’ can be trained into a tree form.Pinching back the stems of Indian Hawthorn will encourage more dense growth of foliage and keep the shrub looking compact. This can be done through the growing season as needed, not taking off more than a few inches of stem at a time.
What are the disadvantages of hawthorn trees?
Hawthorns are susceptible to diseases, most commonly rust and fire blight. Knowing how to identify Hawthorn tree diseases and treat them can help preserve your trees. Fire Blight – An infectious bacterial disease that can be difficult to control. Keep an eye out for wilted and browned blossoms during the spring. Hawthorns can be very durable trees in their native environment, but they are plagued by many pests in the landscape. The two most destructive diseases of hawthorns are rust and fireblight. Rusts find hawthorns to be suitable hosts in which to complete their complex life cycle (see Hawthorn Rust Technical Report).
