There are many different species of trees with shallow root systems, including cottonwood, beech, birch, poplar and several types of maple. Many shallow root systems are considered invasive, as they grow quite quickly, such as willows and spruces.Know More
In addition to spruce trees, most other evergreens also have very shallow roots systems, as they have adapted to live in very shallow soil that is often mostly devoid of nutrients. The soil is generally very acidic due to the large amounts of decaying pine needles, meaning almost no other life can grow near an evergreen.
Sugar maple, Norway maple and silver maple all have extremely shallow roots, especially silver maples, which often have large, exposed roots well above the ground level. This makes it difficult to nearly impossible for grass or other plants to live underneath a silver maple tree.
Cottonwoods, aspens and poplars don't just have shallow roots, but also huge root systems that spread out over a great distance. The roots of these trees are incredibly aggressive and can cause extensive damage to anything they encounter, which is why they should never be planted near homes or other buildings. There are also a number of hybrid poplar species that have been crossbred to grow incredibly quickly, but can wreak havoc on their surroundings during their short lifespan.Learn more about Botany
To identify diseases in maple trees, examine the bark for cankers and lesions, check for signs of girdling roots and analyze the tree to see if verticillium wilt is present. The difficulty of the identification process depends on numerous factors, including the visibility of the symptoms.Full Answer >
Plants respond to gravity by consistently causing their roots to grown downward and their stems to grow upward by sensing the direction of gravity with the use of tiny starch granules within specialized cells. This growth in response to gravity is known as gravitropism.Full Answer >
In contrast to primary growth, which makes a plant’s stem grow taller and its roots grow longer, secondary growth makes a plant grow wider. Primary growth occurs only through a plant’s shoot apical meristems, located at the tip of each branch, and root apical meristems, located at the tip of each root. By contrast, secondary growth occurs in the lateral meristems, which are found in the tree's trunk and branches.Full Answer >
Water lilies reproduce by seed and by new plants sprouting from the large spreading roots, which are underground stems called rhizomes. Petals surround male and female reproductive parts. The petals are only open during the daytime for three days.Full Answer >
