8. What Environmental Factors Influence Longan Cultivation?

Longan cultivation is significantly influenced by several environmental factors that determine the success and productivity of longan orchards.

8.1. Climate

Climate is the most critical factor in longan cultivation. Longans thrive in subtropical and tropical climates characterized by distinct wet and dry periods. Ideal conditions include:

• Temperature: Warm temperatures (70–85°F; 21–29°C) during spring, followed by high summer temperatures (80–95°F; 27–35°C) are best for fruit development.
• Rainfall: Ample rainfall during the growing season is essential, but excessive rains during flowering can cause flower drop and reduce pollination.
• Dry Period: A cool, non-freezing fall/winter period (October–February) with low temperatures (59°F; 15°C or less) is crucial for inducing flowering.

8.2. Soil

Longan trees prefer well-drained soils. They can grow on various soil types, including sandy loams, sand, and calcareous, rocky soils. Good drainage is essential to prevent root rot, which can be detrimental to the tree’s health.

8.3. Altitude

Longans are indigenous to lowland and middle elevations in Southeast Asia, growing at elevations from sea level to 1500 feet (1.8–460 m). Altitude affects temperature and humidity, which in turn influence the tree’s growth and fruit production.

8.4. Wind

While longan trees are tolerant of windy conditions, young leaves are sensitive to strong winds during vegetative flushing. This can result in leaf dehydration, browning, and deformation. Mature trees pruned to limit their height are more likely to survive hurricane-force winds.

8.5. Water Availability

Regular irrigation is recommended from flowering through harvest for optimum fruit production and quality. Withholding or reducing watering during the late summer/early fall through winter is recommended to stop or reduce excessive vegetative growth and enhance subsequent flowering during the spring.

8.6. Sunlight

Longan trees should be planted in full sun for best growth and fruit production. Adequate sunlight is essential for photosynthesis, which drives the tree’s energy production and fruit development.

9. What are the Best Longan Varieties Grown in Different Regions?

Different regions cultivate various longan varieties, each with unique characteristics.

9.1. ‘Kohala’

‘Kohala’ is the most widely planted longan cultivar in Florida, known for its medium to large fruit size, small to medium seed size, and good to very good fruit quality. It bears erratically and is typically harvested in mid-July to August. This variety is well-adapted to the subtropical climate of South Florida and is favored for its reliable production compared to other cultivars.

9.2. ‘Biew Kiew’ (Beow Keow)

‘Biew Kiew’ is a popular variety in Thailand, producing medium to large fruit with small to medium seeds. Its fruit quality is rated as good to very good, though its bearing habit is erratic. This cultivar is typically harvested from late July to September and is known for its sweet and aromatic flavor.

9.3. ‘Edau’ (Daw)

‘Edau’ is another Thai variety that produces medium to large fruit with small to medium seeds. Its fruit quality is considered good, and it is believed to have a more regular bearing habit compared to other Thai cultivars. ‘Edau’ is usually harvested from late July to September.

9.4. ‘Diamond River’ (Petch Sakorn)

‘Diamond River’ is a relatively new cultivar from Thailand, known for its regular bearing and sizable late-season crop. However, its fruit quality is only rated as fair to good, and the tree is susceptible to limb breakage. This variety is typically harvested in September to October.
