What Is Thai Mulberry?
Thai mulberry is a distinctive type of mulberry tree known for its manageable size, multiple varieties, and specific native growing regions. It offers a range of fruit flavors and growth habits, which attract gardeners and farmers alike.
Botanical Description
Thai mulberry (Morus alba ‘Thai’) is typically a dwarf tree, growing about 12 to 15 feet tall and wide. Its compact size makes it suitable for small gardens and limited spaces. The tree produces full-sized, sweet fruit despite its more diminutive stature. Leaves are similar to other Morus alba varieties but may vary slightly depending on the specific cultivar.
This mulberry is prized for its productivity and ability to bear fruit multiple times a year when pruned correctly. The fruit tends to be medium-sized with a firm texture in some cultivars, reducing damage during harvest. This trait is essential for commercial cultivation and home growers who frequently handle fruit.
Varieties of Thai Mulberry
Several varieties fall under the Thai mulberry category, including dwarf and everbearing types. One notable variety is the “Thai Dwarf,” a hybrid known for its medium-sized fruit, which has a flavor profile blending blueberry and raspberry notes. Another important cultivar is “Chaing Mai #60,” valued for its firm fruit that resists damage during picking.
The “Thai Everbearing” type can produce two or more crops annually with proper pruning. Some varieties resemble or overlap with hybrids from Taiwan or other regions, reflecting local breeding efforts. These variations differ primarily in size, fruit flavor, and productivity, offering options tailored to specific purposes and climates.
| Variety | Size Range (ft) | Fruit Characteristics | Productivity |
|---|---|---|---|
| Thai Dwarf | 12-15 | Medium, blueberry/raspberry flavor | High, compact growth |
| Chaing Mai #60 | Medium-large | Firm berries, damage-resistant | Commercially viable |
| Thai Everbearing | Variable | Multiple crops per year | Repeat fruiting |
Native Regions
Thai mulberry originates primarily from Thailand and neighboring Southeast Asian countries. It thrives in warm climates and is well-adapted to subtropical and tropical environments.
The tree grows well in zones with mild winters, such as parts of Florida and southern U.S. states, where it has shown success outside of its native range. Some cultivars, like Chaing Mai #60, may be hardy to zone 7, expanding their cultivation potential into temperate areas with moderate winters. Its native adaptation supports drought tolerance and resilience in diverse conditions.

Research on Thai mulberries suggests potential in managing chronic conditions. Their antioxidants may support liver health by reducing inflammation and promoting detoxification.
Mulberries have shown promise in controlling blood sugar levels, possibly benefiting people with diabetes or insulin resistance. Their nutrient profile also supports cardiovascular health, including blood pressure regulation and cholesterol reduction.
Moreover, mulberries may aid weight management through their high fiber content and appetite-suppressing properties. Some studies suggest potential anti-cancer effects, although further research is needed to confirm this.
The wide range of bioactive compounds in mulberries suggests they could serve as functional food ingredients with health-promoting properties.
Uses of Thai Mulberry
Thai mulberry serves multiple purposes, ranging from food and drink to health applications and industrial uses. Its versatility makes it valuable in several fields, capitalizing on its nutritional and practical qualities.
Culinary Applications
The fruit of the Thai mulberry tree is sweet and can be eaten fresh or used in various culinary applications. It is often incorporated into jams, desserts, and smoothies due to its pleasant flavor. The tree remains relatively small, making it suitable for home gardens and small-scale cultivation focused on fruit production.
Thai mulberry leaves are also processed into tea. This herbal tea is rich in vitamins, minerals, and antioxidants. It is popular in Thailand and surrounding regions for its potential to help regulate blood sugar levels.
Traditional Medicine
In Asian traditional medicine, Thai mulberry leaves have been used for their health properties for centuries. They contain bioactive compounds, such as polyphenols and anthocyanins, which may support metabolic and cardiovascular health.
The leaves and fruit have applications in managing obesity-related risk factors and are sometimes consumed as teas or supplements. These highlight the potential nutraceutical benefits derived from traditional practices and are increasingly being explored in modern studies.
Silk Production
Mulberry leaves are the primary food source for silkworms. In Thailand, the silk industry once depended heavily on locally grown mulberry trees. While silk exports have declined, many farmers have shifted to processing mulberry leaves into a form of tea.
This shift supports local economies and preserves the cultivation of mulberries. The leaves are steamed and prepared like Japanese Sencha green tea, offering an alternative use beyond sericulture.
Cultivation and Growing Conditions
Thai mulberry requires specific environmental factors to grow efficiently and produce quality fruit. Proper attention to the tree’s climate tolerance, soil type, and harvesting practices ensures its health and productivity.
Climate and Soil Requirements
Thai mulberry thrives in warm tropical and subtropical climates, typically within USDA zones 9 to 11. It prefers full sun exposure to promote vigorous growth and fruiting. The tree is sensitive to cold and frost, so protection or growing in an indoor container is necessary in cooler regions.
The preferred soil type is well-drained, loamy soil with deep topsoil to support root expansion. Mulberries tolerate a range of soil pH levels but grow best in slightly acidic to neutral conditions (pH 5.5 to 7.0). Good drainage prevents root rot and other moisture-related diseases, which are common in poorly drained soils.
Harvesting Techniques
Harvesting Thai mulberries requires care due to the fruit’s delicate nature. Mulberries bruise easily, so gentle handling is essential to maintain fruit quality. Typically, fruit is hand-picked when fully ripe, indicated by a deep purple to black color, depending on the variety.
For larger-scale operations, shaking branches over a cloth or tarp can collect berries without damaging them. Using dwarf or everbearing varieties can extend the harvest period, allowing for multiple collections throughout the growing season. After harvest, fruits should be refrigerated promptly to preserve freshness and slow down spoilage.
