Lokao (Rhamnus globosa)
Also known as: Japanese Buckthorn, Glow Globosa
Lokao berries are small, glossy, and spherical, transitioning from green to black as they ripen. The plant is known for its dense, thorny branches, which help it form thick, resilient thickets. Its leaves are ovate with elegant veining, thriving in well-drained soils commonly found in its native woodlands and slopes. Adapted to various environmental conditions, Lokao plants grow vigorously in tropical climates, preferring partial shade and demonstrating considerable drought tolerance.

What Is the Ideal Temperature Range for Lokao?
The ideal temperature range for Rhamnus globosa to thrive is between 60°F and 75°F. Within this range, the plant can perform its physiological processes optimally, leading to healthy growth, proper leaf development, and flowering.
What Soil is Best for Lokao?
Rhamnus globosa thrives in well-drained soils that prevent waterlogging. This is essential for healthy root development and overall plant vigor, ensuring adequate air circulation around the root zone. The presence of organic material enhances the soil structure, leading to better moisture retention and nutrient availability. This fosters robust growth and sustains the plant during dry spells. Providing nutrient-dense soil ensures that Rhamnus globosa has access to necessary macro and micronutrients, facilitating strong growth, healthy foliage, and vibrant berry production.
How to Fertilize Lokao?
When fertilizing Rhamnus globosa, apply 100 grams of a balanced 10-10-10 formula per application for solid fertilizers. Adjust the liquid fertilizer to 50 ml mixed in one liter of water per application to ensure adequate nutrient delivery.
How to Prune Lokao?
Begin by identifying and removing any dead, diseased, or damaged branches using sharp pruning shears. Cutting back to healthy wood promotes the overall health of the plant. After dealing with problematic branches, focus on shaping the plant. Trim back branches to maintain a balanced form, ensuring no part is too heavy or crowded. Snip off the tips of healthy branches to encourage bushier growth. This practice stimulates the plant to produce more stems, leading to a fuller and more robust appearance.
How to Propagate Lokao plant?
1
To propagate Rhamnus globosa from seeds, first collect mature seeds from a healthy plant. Make sure the seeds are fully ripe, as underdeveloped seeds may not germinate.
2
For cutting propagation, select healthy, non-flowering stems. Cut about 4-6 inches and remove the leaves from the lower half. This encourages the cutting to focus on root development.
3
Plant seeds in a seedling tray filled with soil. Cover with a thin layer of soil and water lightly. Keep the tray in a warm, sunny spot and maintain soil moisture to facilitate germination.
How to Repot Lokao plant?
1
Repot Rhamnus globosa when its roots begin to outgrow the current container, evidenced by roots emerging through the drainage holes or the plant becoming root-bound. This typically occurs every one to two years. Choose early spring or summer for repotting when the plant is entering its active growth phase, which helps it recover more quickly.
2
Select a pot that is 1-2 inches larger in diameter than the current one, with adequate drainage holes to prevent waterlogging. A slightly larger pot allows room for root expansion while minimizing excess soil that can retain too much moisture, thereby ensuring healthier root growth.
3
Opt for a well-draining, loamy soil mix containing organic matter such as compost or peat moss. This mix provides the necessary nutrients and aeration, preventing root rot by facilitating proper water drainage, thereby promoting robust growth.
