Breadfruit: Diversity, Conservation and Potential

Breadfruit, a vital staple crop in the Pacific with hundreds of cultivars, is experiencing a decline in diversity due to environmental impacts and loss of cultural knowledge, despite being a part of the International Treaty on Plant Genetic Resources for Food and Agriculture. Actively managed collections in various locations, including the National Tropical Botanical Garden’s extensive field genebank, are focusing on research and in vitro propagation to preserve and distribute breadfruit germplasm, aiming to enhance food security and sustainable agriculture.

Pruning for Health and Productivity

An often-overlooked aspect of breadfruit tree care is pruning, yet it’s vital for maintaining tree health and fruit production. The best time to prune is in early spring, just before the onset of new growth. This timing allows the tree to heal quickly and put its energy into producing new, healthy branches.

When pruning, focus on a few key goals:

Removing Unhealthy Branches: Look for branches that are dead, diseased, or damaged. Removing these helps prevent the spread of disease and encourages healthier growth.
Improving Structure and Sunlight Exposure: Cut back branches that are overcrowding, as well as those growing inward towards the center of the tree. This not only improves the tree’s shape but also ensures better air circulation and sunlight penetration, which are crucial for fruit development.
Enhancing Fruit Production: Pruning also stimulates the growth of new branches, which can lead to more fruit. However, be careful not to over-prune, as this can stress the tree and reduce its yield.
