Common NameJapanese Alpine Cherry
FamilyRosaceae
USDA hardiness6-8
Known Hazards Although no specific mention has been seen for this species, it belongs to a genus where most, if not all members of the genus produce hydrogen cyanide, a poison that gives almonds their characteristic flavour. This toxin is found mainly in the leaves and seed and is readily detected by its bitter taste. It is usually present in too small a quantity to do any harm but any very bitter seed or fruit should not be eaten. In small quantities, hydrogen cyanide has been shown to stimulate respiration and improve digestion, it is also claimed to be of benefit in the treatment of cancer. In excess, however, it can cause respiratory failure and even death.

Why Grow Japanese Alpine Cherry?

Prunus nipponica stands apart from many ornamental cherries because:

✔ Extremely Cold-Hardy

Thrives in mountainous regions where other cherry species struggle.

✔ Ideal for Small Gardens

Compact size fits courtyards, patios, and narrow garden spaces.

Planting Japanese Alpine Cherry (Prunus nipponica)

🌱 Best Location

Choose a site with:

  • Full sun (at least 6 hours daily)
  • Good airflow
  • Slightly acidic to neutral soil
  • Moist but well-drained ground

🏡 Soil Preparation

Blend:

  • garden loam
  • compost
  • gritty sand or perlite (to prevent waterlogging)

Avoid heavy clay unless amended.

🌿 Planting Steps

  1. Dig a hole twice as wide as the root ball.
  2. Place the tree so the root flare rests at soil level.
  3. Backfill using native soil and compost.
  4. Water deeply and mulch surface.

Spacing: 8–12 ft between trees for best flowering visibility.


How to Grow Japanese Alpine Cherry Successfully

🌤 Light Requirements

The tree prospers in full sun, especially for intense flowering.

💧 Watering Needs

  • First year: steady moisture
  • Established trees: drought-resistant

Avoid soggy soil—root rot is a risk.

🍂 Fertilization

Apply a slow-release fertilizer in early spring:

  • NPK 10-10-10 or balanced organic plant feed

✂ Pruning Tips

Minimal pruning required.
Remove:

  • Dead branches
  • Crossing stems
  • Broken limbs after flowering

Avoid heavy pruning—it reduces next year’s blossoms.
