Japanese maple 'Garnet'


The Japanese Maple 'Garnet' is notable for its beautiful foliage and elegant shape. The leaves are finely dissected, giving them a lace-like appearance and are arranged in a palmate fashion typical of the Japanese Maple. Each leaf comprises several narrow lobes that spread out from a central point like the fingers of a hand. They possess a striking garnet-red color that tends to deepen to a richer crimson shade as the season progresses. During the fall, the leaves take on a fiery display ranging from bright red to sometimes purplish hues before they drop, making this cultivar a standout choice for a show of autumn color. The plant's overall form is gracefully rounded, often with a cascading habit, as the branches tend to weep downwards, giving it a soft, mounded silhouette. The bark, which can become visible particularly in winter when the leaves have fallen, adds to the interest with its smooth texture and subtle coloration that sometimes appears slightly lighter than the foliage. The visual interest of the Japanese Maple 'Garnet' extends over the seasons. In spring, the fresh leaves emerge with a bright and vivid tone, signaling the start of the growing season. During summer, the foliage provides dense canopy, offering a textured visual appeal due to the intricately divided leaves. As temperatures cool, the transformation of the foliage to its autumn colors creates a spectacle that is eagerly awaited by enthusiasts. The Japanese Maple 'Garnet' can serve as a dramatic focal point in a garden setting, blending well with a variety of landscapes due to its distinctive color and form. It's commonly used in themed gardens, such as Japanese or zen gardens, due to its Asian origin and is also perfect for adding structure or color contrast in mixed borders.

  • water dropWater

    Japanese Maple 'Garnet' should be watered deeply when the top few inches of soil are dry, which typically amounts to once or twice a week depending on the weather and soil drainage. Water should be applied directly to the base of the plant, avoiding wetting the leaves to prevent fungal diseases. During hot or dry spells, increase the frequency of watering to prevent stress. A young tree may need about 10 to 15 gallons of water per week, while an established tree requires less frequent watering since it has a more extensive root system to access soil moisture.

  • sunLight

    Japanese Maple 'Garnet' thrives best in dappled or partial shade, especially in regions with hot summers. It can tolerate morning sun with afternoon shade or full sun in cooler climates. A spot protected from harsh afternoon sun will help preserve the foliage's vibrant colors while avoiding leaf scorch.

  • thermometerTemperature

    Japanese Maples, including 'Garnet', prefer a temperate climate with temperatures ranging roughly from 15°F in the winter to 85°F in the summer. They can withstand short periods of colder temperatures down to -10 to -20°F, but prolonged exposure can be harmful. The ideal growing temperature for 'Garnet' Japanese Maple is between 60°F and 70°F.

  • scissorsPruning

    Prune Japanese Maple 'Garnet' primarily to maintain its natural shape, remove any dead or damaged branches, and to encourage healthy growth. Pruning is best done in the late winter or early spring before new growth begins. Thin out the canopy to allow light and air to reach all parts of the plant. Pruning can also be done in summer after the leaves fully develop to correct any growth issues.

  • circleLife cycle

    The Japanese Maple 'Garnet' begins its life as a seed, which under suitable conditions, germinates in the spring, requiring moisture and a period of stratification to break dormancy. The seedling emerges and produces its first leaves, which are typically green, gradually developing the characteristic red foliage as it matures. The sapling stage follows, as the tree slowly grows and establishes a strong root system. Over several years, the Japanese Maple 'Garnet' reaches maturity, developing a distinctive, often cascading form with finely dissected, garnet-colored leaves that undergo a seasonal change to bright red or orange in the autumn. The mature tree produces small purple-red flowers in spring, which may lead to the development of winged samaras, or seeds, that disperse in the wind. With proper care, this slow-growing, ornamental tree can live several decades, contributing to the landscape with its striking color and form throughout its lifespan.

      Spring-Early Summer

    • The Japanese Maple 'Garnet' is typically propagated by softwood cuttings during the early summer months when new growth is still flexible. To do this, a cutting about 4 to 6 inches (10 to 15 centimeters) long is taken from a healthy branch, with the leaves removed from the lower half. The cut end is then dipped in rooting hormone to encourage root development and planted in a mix of peat and perlite to provide adequate drainage and aeration. The cutting should be kept in high humidity, using a plastic cover if necessary, and in indirect light until roots have formed, which can take several weeks. Regular misting can help maintain the necessary humidity levels, but it's crucial not to overwater as this can cause the cutting to rot. Once the roots have developed, the new plant can be potted in soil and gradually acclimated to less humid conditions.
