During hot and dry periods, watering frequency should increase to twice a week, while it should be reduced during rainy seasons to prevent waterlogging. It's important to avoid overhead watering and instead water directly at the base of the tree to prevent fungal diseases.

    Japanese Maple 'Waka-midori' prefers temperatures ranging between 60 and 80 degrees Fahrenheit. It can survive minimum temperatures down to approximately 15 to 20 degrees Fahrenheit but should be protected from harsh winter winds. The ideal growing conditions are in regions that offer cool to moderate climates without extreme temperature fluctuations.

  • scissorsPruning

    Pruning of Japanese Maple 'Waka-midori' is primarily for shape and structure rather than stimulating growth, so it should be done cautiously. The best time to prune is during the dormant season, late fall to early winter, to avoid sap bleeding. Prune sparingly, focusing on removing any dead or crossing branches and to maintain its natural form.

  • circleLife cycle

    Acer palmatum 'Waka-midori', commonly known as Japanese Maple 'Waka-midori', begins its life as a seed, which germinates in suitable conditions of moisture and temperature, typically in the spring. The seedling emerges and develops its first set of true leaves, slowly establishing a root system. As the sapling grows, it develops more intricate foliage with the characteristic palmate leaves, and begins to form a woody stem. The tree reaches maturity within several years, wherein it starts to produce flowers followed by winged samaras, or seed pods, which disperse by wind and allow for propagation of new plants. During its mature stage, the Japanese Maple 'Waka-midori' experiences annual cycles of growth in the spring and summer, followed by a brilliant display of fall coloration before shedding its leaves in the winter. The tree can live for many decades, and even over a century, if growing conditions are ideal and it remains unimpeded by disease or environmental stressors.

      Early Spring

    • The Japanese maple 'Waka-midori' is typically propagated through the technique of grafting, which is the most popular method for this type of tree. Grafting involves joining a piece of the 'Waka-midori' scion wood, which contains the buds of the desired cultivar, to the rootstock of another maple that provides vigor and adaptability to the soil. This is done in late winter or early spring when the tree is still dormant. A common grafting method used for Japanese maples is the 'veneer graft', where a thin slice of bark is cut from the rootstock and a matching piece from the scion wood is placed against the cut surface. The two pieces are then firmly bound together and sealed with grafting tape to prevent desiccation. The grafted union must be kept in a humid environment until the graft has taken, which can typically take a few weeks. Once successful, the grafted plant is gradually acclimatized to outdoor conditions before it is planted out in its final position.
