ABOUT

The plant known as 'Blue Dwarf' Japanese larch has a distinctive appearance characterized by its striking bluish-green needles. The needles are soft to the touch and radiate in a whorled pattern around the branches, contributing to the plant's lush, dense look. In spring, the needles emerge with a vibrant, fresh hue, which gradually deepens to a more intense blue-green shade as the seasons progress. This conifer is also notable for its attractive conical shape, with branches that are horizontally arranged, creating an overall symmetrical and orderly form. As the seasons change, the 'Blue Dwarf' Japanese larch offers a dynamic display of color. In autumn, the foliage turns to a delightful golden-yellow before it sheds its needles, since it is one of the few conifer species that is deciduous. The bark on the trunk and branches adds further visual interest; it's textured with a flaky, rough surface that is appealing in the winter landscape when the branches are bare. The 'Blue Dwarf' Japanese larch also produces small cones, which begin as a soft green and eventually mature to a woody brown. The cones are diminutive and oval-shaped, adding a subtle decorative touch to the plant. Though small in size, the cones contribute to the overall aesthetic during different seasons. Overall, 'Blue Dwarf' Japanese larch is admired for its seasonal beauty and unique needle color, making it a desirable addition to landscapes seeking visual interest throughout the year.

    The Blue Dwarf Japanese Larch should be watered deeply once a week, allowing for slight drying between waterings. Provide the tree with about 1-2 gallons of water for each watering session, depending on the size of the tree and the weather conditions. During periods of drought or extreme heat, it may need additional water. Adjust the watering frequency to less often during cooler, rainy periods. Ensure the water penetrates the soil to reach the tree's roots, avoiding shallow sprinklings that don't supply enough moisture.

  • sunLight

    The Blue Dwarf Japanese Larch thrives best in full sun. It requires at least six hours of direct sunlight daily to maintain its health and stunted growth habit. The ideal spot for this tree is in an open area away from taller structures or trees that could create significant shade.

  • thermometerTemperature

    The Blue Dwarf Japanese Larch is hardy and can withstand a range of temperatures, from as low as -30 degrees Fahrenheit in winter to the high summer temperatures typically found in its hardiness zones. The ideal growing temperatures for this plant are between 60 and 70 degrees Fahrenheit. It should be protected from extreme heat to prevent stress.

  • scissorsPruning

    Prune the Blue Dwarf Japanese Larch to maintain its shape and size, and remove any dead or broken branches. The best time for pruning is late winter or early spring before the new growth starts. Pruning once a year is usually enough to keep the tree healthy and well-shaped.

  • circleLife cycle

    The life of a Japanese Larch 'Blue Dwarf' begins with seed germination, typically in the spring when temperatures become conducive for growth. The seedling stage is marked by the emergence of the first shoots and roots, as it establishes itself in the soil. Following the seedling stage, the sapling phase sees rapid vertical growth and the development of the conical shape characteristic of this cultivar. As it matures, the Japanese Larch 'Blue Dwarf' enters a long vegetative stage where it develops dense, bluish-green needle-like foliage and a sturdy trunk, with slow but consistent growth over the years. The reproductive stage involves the production of small cones in the spring, following which the plant can pollinate and produce seeds, thereby continuing its life cycle. Finally, after many years, the plant will reach senescence, where growth slows and it may become more susceptible to environmental stresses, before eventually dying.

    • The most popular method of propagating the Japanese Larch 'Blue Dwarf', a variety of Larix kaempferi, is through grafting. This technique involves joining a piece of the 'Blue Dwarf' with the root system of a compatible Larix species, ensuring the desirable traits of 'Blue Dwarf' are maintained. Grafting is best done during the late winter or early spring before new growth begins. To graft, a scion, which is a short piece of stem growth from the 'Blue Dwarf', is cut to include several buds. The scion is then inserted into a cut made in the rootstock, ensuring a snug fit. It is essential that the cambium layers (the growing tissues) of both the scion and the rootstock are aligned. The graft union is then wrapped securely and sealed to prevent desiccation and contamination, with the graft expected to heal and grow within a few weeks.
