Soil For Planting Longan Tree

Longan trees prefers slightly acidic, free-draining and nutrition rich soil\Use a mixture of 70% potting mix, 15% Compost and 15% river sand. The compost makes the soil slightly acidic and nutrition rich, white the river sand makes it free-draining. This soil combination ensures moisture retention, proper aeration and nutrient availability for your longan tree.

Planting Depth

Plant the longan tree at the same depth as it was in its old container. Ensure to cover the roots with soil adequately, but don't bury the trunk too deep.

Positioning

Place your potted longan tree in a sunny location. Longans thrive in full sun, at least 6 to 8 hours of sunlight daily.

Move the pot under cover in garage during extreme winter conditions.

Move the pot under cover in case of excessive rain.

Watering

Keep the soil of young tree moist but not wet. Young longan plant will need watering at least once a day during hot days.

Water only when the top one inch soil gets dry. Continuously wet soil may kill the tree. In winter, the plant may not need water for several days.

Over-watering or under-watering will cause leaves to turn yellow.

Do not use a saucer at the bottom of the pot for drainage of excess water or if you use it then remove the water from it.

Over fertilization can prevent fruit development.

Top dress with compost or cow manure. Then put a layer of mulch and water.

Pruning

Regular pruning helps shape the longan tree and encourages better air circulation.

Pruning the tips of branches during spring and summer will grow more branches and make the tree compact and dense.

First pruning is done when the plant is seedling. Cut at the height of about 6 inch to promote growth of new branches. You can pinch again to promote more branches.

Cut back any dead or diseased branches.

You can prune the tree after harvest to control its size and shape.

Pests and Diseases

The most common pest on longan tree are aphids and scales on new shoots, flowers and fruits. A periodic spray of neem oil may treat the insect problems.

Longan tree is relatively free from major diseases.



Harvesting Longans

Patience is key when growing longan trees, as they typically take several years to start bearing fruit.

The longan grown from seed will start to grow flowers and fruits after 6 years or more. The longan tree does not bear fruit every year.

Longan is self-pollinating, so other tree is not needed for pollination. Hand pollination can increase fruit production.

Excessive rain during flowering may cause flower drop and reduce pollination. Move the pot under cover.

If your longan tree is not bearing fruit even it has become very old, then how to make your longan tree to bear fruit? Spray potassium chlorate or sodium hypochlorite on older leaves to induce flowering of longan trees in Thailand, Taiwan, Florida and Hawaii.

Longans do not continue to ripen after they are picked from the tree, so be sure that the fruits are ripe before harvesting. Ripe longans have a brown, leathery skin and a sweet aroma. You may pick one fruit and taste it before harvesting.

You can refrigerate the fruits in plastic bag for later use.

Growing a longan tree in a pot is a rewarding experience. With proper care, attention, and the right growing conditions, your potted longan tree can provide you with a bountiful harvest of delicious homegrown longans right at your home.
