Is Indian white mulberry fruit safe to eat?

What are the health benefits of mulberry leaves?

Mulberry leaves, particularly from Morus alba varieties, contain compounds that have been studied for their potential to support healthy blood glucose levels. Traditional Ayurvedic medicine also uses leaf preparations for mild anti-inflammatory purposes and general wellness. These uses are rooted in traditional practice and scientific research is ongoing.

Why is Morus alba var. indica important for silk production?

The silkworm Bombyx mori feeds almost exclusively on mulberry leaves, and Morus alba var. indica produces leaves with a nutritional profile and texture well-suited to silkworm rearing. Its adaptability to tropical climates and high leaf yield under managed pruning make it the preferred sericulture crop across South and Southeast Asia.

Where does the Indian white mulberry grow in Sri Lanka?

Morus alba var. indica can be grown across much of Sri Lanka, from sea level up to around 1,200 metres. It thrives in warm, well-drained conditions and is found in home gardens, smallholder farms, and areas where traditional sericulture has been practised. The intermediate and dry zones provide particularly suitable conditions.

How is Morus alba var. indica different from black mulberry?

The Indian white mulberry produces small, pale-coloured fruit with a mild flavour, while Morus nigra (black mulberry) produces larger, dark-purple fruit with a richer, more tart taste. Black mulberry is generally preferred for fresh eating and culinary use, whereas the Indian white mulberry is primarily grown for silkworm feed.

What type of soil and climate does Indian white mulberry need?

The tree prefers well-drained, loamy soil and full sun, though it tolerates a range of soil types. It thrives in tropical to subtropical climates with warm temperatures year-round. Once established, it is relatively drought-tolerant, though regular water encourages better leaf and fruit production.
