Acer palmatum
Japanese Maple thrives in full sun to partial shade, protected from intense midday sun. It needs fertile, well-draining, slightly acidic soil (pH 5.5–6.5). Water regularly but avoid waterlogging. Annual spring pruning removes dead wood and maintains shape. Hardy to cold, tolerating sub-zero temperatures, but protect from strong dry winds.

How to Propagate Japanese Maple?
By Seeds
Seeds require cold stratification to germinate. The process is slow but results in genetically diverse plants.
- 1 Collect mature seeds in autumn
- 2 Cold-stratify seeds in refrigerator for 60-90 days before planting
- 3 Sow in moist, well-draining soil in spring
- 4 Keep in a sheltered location until germination
- 5 Transplant seedlings when 10-15 cm tall
By Cuttings
Cuttings have a lower success rate than seeds, but produce plants identical to the parent.
- 1 Cut semi-hardwood stems in summer, 10-15 cm long
- 2 Remove lower leaves, leaving 2-3 pairs at the top
- 3 Apply rooting hormone to the base
- 4 Plant in moist, porous substrate
- 5 Keep in a humid environment with indirect light for 6-8 weeks
By Grafting
Commercially preferred method to preserve the characteristics of special cultivars.
- 1 Use a strong-rooted Acer palmatum rootstock
- 2 Perform cleft grafting in winter or early spring
- 3 Secure the graft with grafting tape
- 4 Keep in a humid environment until the union consolidates
- 5 Remove the tape after 4-6 weeks

What Diseases Commonly Affect Japanese Maple?
TLDR: Japanese Maple is susceptible to 11 known diseases. Monitor regularly for early detection.
Anthracnose
Anthracnose is a fungal disease caused by fungi in the genus Colletotrichum that affects many plants, including vegetables, fruits, and trees. The disease thrives in cool, wet conditions, causing dark, sunken lesions on leaves, stems, flowers, and fruits.
Powdery Mildew
Powdery mildew is a common fungal disease caused by various fungi species including Erysiphe, Podosphaera, Oïdium, and Leveillula. It affects over 10,000 plant species worldwide. The disease thrives in warm, dry climates with high humidity and appears as a distinctive white powdery coating on plant surfaces.
Verticillium Wilt
Verticillium wilt is a soil-borne fungal disease caused primarily by the fungi Verticillium dahliae and V. albo-atrum. These pathogens infect plant roots and grow within the vascular tissues, blocking water and nutrient transport, resulting in wilting and eventual plant death. The disease affects over 350 plant species including vegetables, fruits, ornamental flowers, and trees. The fungi can survive in soil for more than 10 years as resistant structures called microsclerotia.
Aphids
Aphids are small, soft-bodied, pear-shaped insects (1/16 to 1/8 inch long) that feed by sucking nutrient-rich sap from plants. They reproduce rapidly and can quickly weaken plants, causing distorted growth and transmitting plant viruses. Aphids come in various colors including green, black, red, yellow, brown, and gray. They secrete honeydew, a sticky substance that attracts ants and encourages sooty mold growth.
Meaning & Symbolism
No Japão, o bordo japonês simboliza paz, serenidade e a beleza efêmera das estações. É frequentemente associado à prática do momijigari, a contemplação das folhas de outono.
Fun Facts
Acer palmatum has over 1,000 registered cultivars, with extraordinary variations in leaf color, texture, and shape.
In Japan, the practice of admiring colorful maple leaves in autumn is called "momijigari" and is as traditional as cherry blossom viewing in spring.
Some Acer palmatum specimens can live for over 100 years when grown in ideal conditions.
Japanese maple is one of the most used trees in the art of bonsai, capable of being shaped to represent entire landscapes in miniature.
