The process of trimming and shaping oleander shrubs or trees is a horticultural practice employed to manage plant size, encourage flowering, and remove dead or diseased wood. It involves selectively cutting back stems and branches to achieve desired aesthetic and health outcomes for the plant. For instance, overgrown oleanders can be significantly reduced in size through judicious removal of older canes.
Proper trimming promotes vigorous growth and abundant blooms in subsequent seasons. Furthermore, removing dead or damaged portions of the plant prevents the spread of disease and improves overall plant health. Historically, skillful shaping has been used to create hedges, screens, and ornamental features using this versatile plant.
