![]() ![]() The lower the number, the colder the winter. There are 13 hardiness zones across the country. If you are not familiar with these zones, the United States is divided into hardiness zones based on each region’s weather patterns. These trees do best in hardiness zones 5 through 8. Young trees should be kept moist to prevent their shallow root structures from drying out and weakening, particularly during the hot summer months. Through this woodland grove, they line both sides of the carriage road. Japanese maple trees are particularly suitable for borders and ornamental paths because their root systems are compact and not invasive. If I can, I like to prune and groom these Japanese maples myself. Small, corrective cuts can be made any time of year. Cut out scraggly interior twigs and branches, but leave the structural branches alone. Japanese maples typically grow about one-foot per year for the first 50-years, but they can live to be more than a hundred.Īny heavy pruning should be done in late winter before leaf buds begin to open. Japanese maple forms can be weeping, rounded, dwarf, mounding, upright, or cascading. These leaves are deeply divided, but each lobe is also dissected, giving them a lacy effect. The leaf lobes are more divided, nearly to the leaf base. The leaves in the Palmatum Group are most typical of the wild species. Red leafed cultivars are the most popular, followed by green shrubs with deeply dissected leaves. Here, one can see the leaves transforming from green to dark burgundy. A sudden cold snap could turn the leaves more plum-brown seemingly overnight, skipping the vibrantly red stage altogether. Leaf color best develops when nighttime temperatures remain above freezing but below 45-degrees Fahrenheit. This is because the color changes occur with gradually cooling temperatures – not cold snaps. Unusually warm early fall weather may even prevent the leaves from turning red. These cool nighttime temperatures trigger the leaf-changing process. Here in the Northeast, fall weather usually arrives in September, with temperatures cooling off rapidly at night even when the days are still warm. The colors are a result of climate, weather, and environmental conditions. The heavy leaf cover on the ground also enriches the soil and adds even more fall color.īut those brilliant fall colors aren’t a guarantee. I love the contrast between the bright reds, oranges, yellows, and greens in this grove. In Japan, the maple is called the “autumn welcoming tree” and is planted in the western portion of gardens – the direction from which fall arrives there. Japanese maples are native to areas of Japan, Korea, China, and Russia. Every year, all of us here at the farm wait for this woodland to burst with color. With more than a thousand varieties and cultivars including hybrids, the iconic Japanese maple tree is among the most versatile small trees for use in the landscape. Few trees are as beautiful as the Japanese maple. ![]()
