The tallest Leyland cypress documented is about 40 m (130 ft) tall and still growing. [18] However, because their roots are relatively shallow, a large leylandii tends to topple over. The shallow root structure also means that it is poorly adapted to areas with hot summers, such as the southern half of the United States.
In agriculture and gardening, transplanting or replanting is the technique of moving a plant from one location to another. Most often this takes the form of starting a plant from seed in optimal conditions, such as in a greenhouse or protected nursery bed , then replanting it in another, usually outdoor, growing location.
Plant propagation is the process of plant reproduction of a species or cultivar, and it can be sexual or asexual. It can happen through the use of vegetative parts of the plants, such as leaves, stems, and roots to produce new plants or through growth from specialized vegetative plant parts.
A root ball [1] is the mass of roots and growing media at the base of a plant such as trees, shrubs, and other perennials and annual plants. [2] The appearance and structure of the root ball will be largely dependent on the method of growing used in the production of the plant.
Root trainer pots. Many pot designs train the roots. One example is a truncated plastic cone in which a seedling is planted. There is a drainage hole at the bottom and the main tap root tends to grow towards this. What this achieves is to encourage the roots to grow a denser system of root hairs.
The roots, when dried and ground into powder, were also used as an insecticide. [11] Western American Indian tribes have a long history of using these plants medicinally, and combined minute amounts of the winter-harvested root of these plants with Salvia dorii to potentiate the effects and reduce the herb's toxicity.
In geometry, the Lemoine point, Grebe point or symmedian point is the intersection of the three symmedians (medians reflected at the associated angle bisectors) of a triangle. Ross Honsberger called its existence "one of the crown jewels of modern geometry". [1] In the Encyclopedia of Triangle Centers the symmedian point appears as the sixth ...
A rosette of leaves at the base of a dandelion Rosette growth form of the liverwort Ricciocarpos natans. In botany, a rosette is a circular arrangement of leaves or of structures resembling leaves. In flowering plants, rosettes usually sit near the soil, but they can also be at the top of an otherwise naked branch or trunk.
