Tamukeyama Japanese Maple

Tamukeyama Japanese Maple (Acer palmatum var. dissectum ‘Tamukeyama’)

This is a laceleaf, weeping maple that thrives with careful planting and consistent moisture.

Planting Steps

• Location: Partial shade is best (morning sun, afternoon shade). Protect from strong wind.
• Soil: Well-draining, slightly acidic soil. Avoid heavy clay unless amended.
• Hole: Dig 2–3× wider than the root ball, same depth. Do NOT plant deeper than it sat in the pot.
• Set Plant: Loosen roots gently. Place so root flare is just above soil level.
• Backfill: Use native soil mixed with compost (about 20–30%). Firm lightly.
• Water In: Soak deeply immediately after planting to remove air pockets.
• Mulch: 2–3 inches of mulch, keep 2 inches away from trunk.

Watering (Critical)

• First 2 weeks: Water every 2–3 days, slow deep soak.
• Next 2–3 months: 1–2 times per week depending on weather.
• After establishment (1 year): Weekly deep watering in dry periods.
• Always water at the base—avoid wetting leaves.

Ongoing Care

• Fertilizer: Light feeding in early spring with balanced slow-release fertilizer. Do not over-fertilize.
• Pruning: Minimal. Remove dead or crossing branches in late winter.
• Protection: Avoid hot afternoon sun and drying winds to prevent leaf scorch.

Container Planting

• Use a large pot with drainage holes.
• High-quality potting mix (not garden soil).
• Water more frequently—containers dry out faster.
• Winter: Protect roots from freezing (move or insulate pot).

Keep soil evenly moist, not soggy. Consistency is the key to keeping foliage vibrant.

Tamukeyama Japanese Maple FAQs

• 1. How big does Tamukeyama Japanese Maple get?
  Tamukeyama has a low, spreading habit that usually reaches about 6 to 8 feet tall and can grow up to around 12 feet wide over time. It grows wider than tall, which gives it that graceful, layered look people love in borders, foundation plantings, and focal-point beds.
• 2. Will it keep its red color through the season?
  Yes—this is one of the reasons Tamukeyama has such a strong reputation. Its finely cut foliage emerges deep red to purple-red, holds its color well through summer better than many laceleaf types, and then brightens to scarlet-red in fall. It is the kind of tree that does not fade into the background when summer turns up the heat.
• 3. Does Tamukeyama grow in full sun or shade?
  Tamukeyama grows best in full sun to partial shade. In cooler climates, it can handle more sun, while in hotter southern areas it benefits from some afternoon shade to help protect the foliage from scorch. Give it moist, well-drained soil and a spot sheltered from harsh wind, and it settles in nicely.
• 4. Can I grow Tamukeyama Japanese Maple in a container?
  Yes, it can do very well in a large container, which makes it a great choice for patios, courtyards, and entryways. Its naturally compact, mounding shape works especially well in pots, where the cascading branches can really show off. Just use a roomy container with drainage holes and do not let the soil dry out completely. The bonus is that a container puts its structure and color right where people will notice it.
• 5. Does Tamukeyama flower or produce anything to harvest?
  Tamukeyama may produce small spring flowers like other Japanese maples, followed by winged seeds called samaras later in the season, but it is grown mainly for its foliage and form—not for harvest. Pollination is not usually a selling point with this tree, though the flowers can be visited by insects and develop seed if conditions are right. In other words, this one earns its keep as living architecture more than as a producer.
