Fertilizing
Feed your Winter Hazel bonsai every two weeks throughout the growing season using an acidic/ericaceous fertilizer, as this species strongly dislikes lime. Unlike regular hazels, Winter Hazels require specifically acidic conditions to thrive. During the dormant winter period, reduce or stop fertilizing altogether to allow the tree to rest naturally. A balanced approach to fertilizing helps maintain the tree's health while promoting the development of its signature spring flowers.
Placement
Position your Winter Hazel in an outdoor location that receives morning sun and afternoon shade during the hottest summer months. While fully hardy, this species needs protection from late spring frosts which can damage its delicate flowers. An east or west-facing position often works best, providing adequate light while protecting from harsh afternoon sun and strong winds. Winter Hazels cannot thrive indoors as they need seasonal changes and full sun exposure for proper growth and flowering.
Pruning
Timing is crucial when pruning Winter Hazel bonsai. The main pruning should be done in early autumn after the flowers have faded, but before the new flower buds begin forming for the following season. Remove dead or crossing branches and trim back to maintain the desired shape, being careful not to remove too much foliage at once. Winter Hazel is particularly well-suited for informal upright styles in medium to extra-large sizes, and while it responds well to structural pruning, always maintain enough foliage to ensure the tree's health.
Repotting
Repot your Winter Hazel every 2-3 years after flowering has finished in the spring, using a special lime-free bonsai soil mix. The soil should have excellent drainage properties and maintain a slightly acidic pH between 5-6, never exceeding 7.0. When repotting, avoid aggressive root pruning and instead focus on maintaining a healthy root system while removing only what's necessary. Choose a pot that complements the tree's size while ensuring adequate drainage, and remember to use proper aftercare techniques to help the tree recover.
Watering
Water your Winter Hazel moderately throughout the growing season, ensuring the rootball stays moist but never waterlogged. During summer months, daily watering may be necessary, while in cooler weather, reduce watering frequency but never allow the soil to dry out completely. The key is maintaining consistent moisture levels - check the top inch of soil daily, and water thoroughly when it begins to feel dry. During periods of active growth and flowering, the tree may need more frequent watering to support healthy development.
