Lateral: Relating to the side or extending outward from the center; in gardening, it often refers to plant growth, branching patterns, or the spread of roots.
Lateral growth in plants refers to the development of branches, stems, or roots that extend outward from the main axis. Think of the side branches that grow out from the main trunk of a tree or the lateral roots that spread out from the base of a plant. This type of growth is essential for increasing the plant’s overall size and reach, allowing it to capture more sunlight, access more nutrients and water, and become more stable.
For home gardeners, understanding lateral growth can be helpful for pruning, training, and spacing plants. Encouraging lateral branching can create a bushier, fuller plant while controlling lateral growth can help maintain a desired shape or size. When planting, it’s important to consider the potential lateral spread of roots, especially for trees and shrubs, to avoid overcrowding or competition with other plants. Observing the lateral growth patterns of your plants can also give you clues about their health and growing conditions.
