Fertilizing
The Common Ash has modest fertilizing needs. Feed only once or twice during the growing season (spring to autumn) using a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium. Keep applications minimal as this species doesn't require heavy feeding to thrive.
Placement
Common Ash is spectacularly hardy, requiring no special winter protection as it's native to the northern hemisphere. Place the tree outside year-round in bright sunlight. During summer, it can handle full sun exposure. For optimal growth, ensure good air circulation and avoid placing near heaters or air conditioners which can affect humidity and temperature. Indoor placement is not recommended as this species requires full aeration and natural sunlight.
Pruning
Regular pruning and pinching of new shoots can be done throughout the growing season to maintain the tree's shape. Thanks to its fast-growing nature, the Common Ash responds well to consistent pruning of the apex and secondary shoots. This species works well for various styles including literati and forest arrangements. When wiring, use wire that matches the branch thickness - too thick will damage bark, too thin won't be effective. Wiring can be done year-round but shouldn't be left on longer than one growing season.
Repotting
These vigorous trees benefit from yearly repotting, ideally during early spring when the tree is just waking up. Use a well-draining soil mix with a neutral to slightly higher pH (5-6 but not over 7). When repotting, avoid removing too much of the root mass. A blend of pumice, lava rock, and pine bark works well for proper drainage while retaining adequate moisture. Always use a pot with good drainage holes.
Watering
Regular watering throughout the growing season is vital, with consistent soil moisture being crucial - never allow the soil to dry out completely as this can cause die-back and leaf drop. However, avoid overwatering as this can lead to root rot. During winter, reduce watering and only water enough to maintain basic soil moisture. Check soil regularly by feeling the top layer - water thoroughly when it starts feeling slightly dry.
