Longan (Dimocarpus longan), sometimes called “dragon’s eye,” is a tropical fruit closely related to lychee. The fruit has a sweet, aromatic flavor and grows very well in parts of Florida with warm temperatures and mild winters. Many home gardeners in Central and South Florida successfully grow longan trees as part of backyard food forests or tropical fruit collections. �
What’s Happening Around Florida
With proper care, a longan tree can produce fruit for decades while also serving as an attractive shade tree in the landscape.
1. Is Central Florida Good for Longan?
Central Florida is near the northern edge of longan’s comfortable growing range, but it can still be very productive with proper care.
Ideal Conditions
Longan trees perform best with:
Warm spring temperatures 70–85°F (21–29°C)
Hot summers 80–95°F (27–35°C)
A cool, dry winter period to trigger flowering �

Central Florida’s climate usually meets these requirements, though occasional freezes are the biggest challenge.
Cold Tolerance
Young trees can be damaged near 30–31°F (-1°C)
Mature trees may tolerate slightly colder temperatures but can still suffer damage �
Growables
Tip: Plant trees in warm microclimates such as:
South side of a house
Near a wall that stores heat
Protected from north winds
2. Choosing the Best Longan Variety
Some varieties perform better in Florida than others.
Recommended Varieties
Kohala
Most widely grown in Florida
Reliable producer
Good fruit size and flavor �

Biew Kiew
Vigorous tree
Large fruit clusters
Edau (Daw)
Earlier fruiting season
Bing
Large fruit and excellent flavor �
Cultivating Flora
For home gardeners in Central Florida, Kohala is usually the easiest and most reliable choice.
3. Planting Location
Selecting the right site is critical for success.
Sun
Longan trees require:
Full sun (8+ hours daily) for best growth and fruiting �
Medium
Spacing
Trees become large.
Typical mature size:
20–30 ft tall
Up to 45 ft wide if not pruned �
A Natural Farm
Recommended spacing:
22–25 ft from buildings or other trees �

Soil
Central Florida sandy soil is actually good for longan.
Preferred soil characteristics:
Well-drained
Sandy or sandy loam
pH 5.5–6.5 �
Cultivating Flora +1
Poor drainage is one of the few soil conditions longan does not tolerate.
4. Planting Your Longan Tree
Best Time to Plant
In Central Florida:
Late spring to early summer is ideal
Planting during the rainy season helps establishment �

Planting Steps
Remove grass in a 3–10 ft circle around the planting area.
Dig a hole 3–4 times wider than the container.
Make the hole about the same depth as the root ball.
Place the tree so the top of the root ball is slightly above soil level.
Backfill with the native soil.
Water deeply.
Apply 2–4 inches of mulch, keeping it away from the trunk.
Avoid planting trees that are root-bound in small containers, as these may establish poorly. �

5. Watering
Longan trees have moderate drought tolerance but still need consistent watering when young.
Young Trees (First 2 Years)
Water:
2–3 times per week during dry periods
Mature Trees
Water mainly during:
Flowering
Fruit development
Interestingly, a dry period in fall and winter actually helps stimulate flowering. �

6. Fertilizing
Fertilizing is important for good growth and fruiting.
Young Trees
Apply a balanced fertilizer:
Example schedule:
Every 6–8 weeks during the growing season
Mature Trees
Use a low-nitrogen fertilizer two or three times during the rainy season (May–October). �
What’s Happening Around Florida
Also beneficial:
Chelated iron drenches
Micronutrient sprays
These help prevent nutrient deficiencies common in Florida soils.
7. Pruning and Tree Size Control
Longan trees naturally grow large and upright.
Pruning tips:
Prune after harvest
Remove strong vertical branches
Encourage lateral growth
This keeps the tree shorter and easier to harvest.
A well-maintained backyard tree is often kept 10–15 ft tall.
8. Flowering and Fruit Production
Longan trees flower in late winter to early spring.
Conditions that encourage flowering:
Cool winter temperatures
Dry conditions
Warm, wet winters can reduce fruiting. �
Ask IFAS – Powered by EDIS
Time to First Fruit
Grafted or air-layered trees: 2–4 years
Seed-grown trees: 6+ years
9. Harvest Season in Florida
In Florida, longan fruit usually ripens:
Mid-July through early September (peak in August). �
Ask IFAS – Powered by EDIS
Harvest when:
Fruit turns tan/brown
Clusters are fully developed
Flavor becomes sweet
Cut whole fruit clusters with pruners rather than pulling them off.
10. Common Problems
Cold Damage
The biggest issue in Central Florida.
Protection methods:
Frost cloth
Christmas lights for warmth
Plant near structures
Flower Drop
Caused by:
Heavy rain
Excess fertilizer
Warm winters
Pests
Occasional pests include:
Lychee webworm
Scale insects
Fruit-feeding birds
Most backyard trees have minimal pest issues.
11. Growing Longan in Containers
Longan can be grown in large containers, which is helpful in colder areas.
Requirements:
25–30 gallon pot
Well-drained soil mix
Regular pruning
Container trees are easier to protect during freezes.
12. Long-Term Care
A well-maintained longan tree can:
Produce fruit for 30+ years
Become a beautiful landscape tree
Yield hundreds of pounds of fruit annually when mature.
✅ Summary for Central Florida Gardeners
Longan is one of the easiest tropical fruit trees to grow in Florida if you:
Plant in full sun
Ensure excellent drainage
Protect from freezes
Allow a cool, dry winter period
Many gardeners in Central Florida successfully grow longan trees alongside mango, guava, and jackfruit.
