The shaping and pruning of red-fleshed honey pomelo trees are essential for optimizing growth, fruit production, and tree structure. Based on the biological characteristics of this variety, two primary training methods are commonly used: the "Happy Round Head" shape and the "Natural Happy" shape.
For the **Happy Round Head** technique, the goal is to create a balanced, well-structured canopy with strong main branches that grow straight upward. In the first year, young seedlings are pruned to select 2–3 strong, evenly spaced shoots as the main branches. These are supported and trained to grow at an appropriate angle. As the main branches reach 35 cm, they are pinched to encourage branching. In the second year, weak or thin branches are removed, and one strong shoot is selected to extend the main branch. Side branches are also cultivated to ensure good light penetration and prevent overcrowding. By the third year, the focus shifts to developing secondary branches and ensuring even distribution of foliage. Throughout the process, it's important to remove excessive vertical shoots from the center to avoid forming dominant branches that could disrupt the tree’s balance.
The **Natural Happy** shape follows similar principles but allows more flexibility in branch placement. This method emphasizes natural growth patterns while maintaining a well-spaced, open structure. Pruning is done selectively to remove upright or dense branches that might hinder light access or cause crowding. The main branches should be limited to 3–4, with each spaced appropriately to allow for proper air circulation and sunlight penetration. The angles of the main branches are adjusted to promote a healthy, balanced growth pattern.
When shaping young trees, attention should be given to trunk height, number of main branches, and their angles. A shorter trunk (around 25–35 cm) encourages faster canopy formation and earlier fruiting. The number of main branches should be carefully managed—too many can lead to poor nutrient distribution, while too few may result in sparse growth. Branch angles are crucial for structural integrity; they should be wide enough to support fruit load without sagging or breaking.
Pruning practices vary depending on the tree's age and stage. For young trees, regular tipping helps control shoot growth and promotes the development of productive branches. In mature trees, winter pruning focuses on removing dead or diseased branches, while summer pruning controls excessive growth and improves light exposure. For aging trees, rejuvenation techniques such as branch replacement or selective cutting help restore vigor and productivity.
Overall, proper shaping and pruning not only enhance tree health and fruit quality but also make management easier and more efficient. Consistent care ensures that the tree remains productive and structurally sound over time.
