What specifications should be included for shrub form trees and multi-stem plants?

The inclusion of height, depth, and spread is essential in specifications for shrub form trees and multi-stem plants. Height refers to how tall the plant will grow, providing insight into its potential vertical reach and its suitability for specific planting locations, such as near structures or utility lines. Depth indicates how deep the root system should go, which is crucial for ensuring that the plant is established properly and has the necessary nutrient and water access. Spread describes the width of the plant as it matures, giving guidance on how much horizontal space it will occupy and helping in planning for spacing between plants to avoid overcrowding and competition for resources.

This combination of measurements allows for better planning and management of plant placement in landscaping and urban forestry projects, ensuring that the plants will thrive in their designated environments while maintaining visual appeal and functional benefits. In contrast, the other answer choices mention specifications that are either less relevant or not standard for describing the form and growth characteristics of these types of plants.
