Planting, Spacing & Care

How to Plant Acer palmatum dissectum 'Seiryu'

Spot Selection: A location with filtered sunlight, especially protected from the afternoon sun, is ideal.
Soil Enhancement: Integrate organic compost into the soil to improve its structure and drainage properties.
Digging Depth: The hole should be approximately double the width of the tree's root ball.
Positioning the Tree: Gently place the 'Seiryu' in the hole, backfill with soil, and press softly.
Immediate Watering: Thoroughly water post-planting to support root development.

Hedging & Screening: Not suitable for hedging.

Caring for Acer palmatum dissectum 'Seiryu'

Watering: Maintain uniform moisture, particularly during warmer or drier periods. Overwatering should be avoided.
Pruning: Minimal pruning is needed; if required, focus on dead or overlapping branches during the dormant season.
Mulching: A protective layer of organic mulch helps retain moisture and moderates soil temperature.
Pests/Diseases: Generally pest-resistant, but periodic checks for aphids or other common pests are advised.

The 'Seiryu' Japanese Maple is adaptable and can be optimized for various soil types to ensure robust growth:

Ideal Drainage: Prefers well-draining soil that allows excess water to escape, preventing root rot and disease.

Well-Draining Soil: This soil type is perfect as it combines airiness with moisture retention, promoting healthy root development and vibrant foliage. No changes needed unless you want to enrich with a bit of organic mulch for nutrient boost.

Sandy Soil: While excellent for drainage, sandy soil lacks nutrient retention. Optimize by adding well-rotted compost and worm castings to increase its fertility and water-holding capacity, which will support more consistent growth.

Clay Soil: Clay soil's density can suffocate roots but can be optimized by incorporating coarse sand and organic matter like compost or leaf mold. This amendment improves the soil structure, enhances aeration, and ensures better drainage.

Loamy Soil: Loamy soil is naturally well-balanced and ideal for 'Seiryu'. Enhance this type with organic mulch to slowly add nutrients and maintain soil health.

Peaty Soil: Rich in organic materials, peaty soil retains moisture well but may require improved drainage. Mix in coarse sand and perlite to optimize drainage while maintaining its high nutrient content.

Acer palmatum dissectum 'Seiryu' (Japanese Maple) is expected to grow 30 – 45 cm per year(moderate).
