Fraxinus uhdei, commonly known as Shamel Ash or Mexican Ash, is a deciduous tree belonging to the Oleaceae family. Native to Mexico and Central America, this tree is widely cultivated around the world due to its ornamental value and rapid growth rate. It can reach heights of 20 to 30 meters, with a broad crown that provides ample shade. The leaves are compound, consisting of 5 to 9 dark green, glossy, lance-shaped leaflets. In autumn, these leaves turn yellow before falling off.
The bark of Fraxinus uhdei is grayish-brown with deep furrows as it matures. In spring, the tree produces small greenish-white flowers, which emerge before the leaves. These flowers later develop into winged fruits called samaras, or keys.
Fraxinus uhdei thrives in full sun exposure but can also tolerate partial shade. It grows well in well-drained soils and can even withstand poor soils, as long as they are not waterlogged.
The wood of Fraxinus uhdei is strong yet flexible, making it ideal for furniture, flooring, and sports equipment like baseball bats, thanks to its shock-absorbing properties.
Although this tree is prized as an ornamental species for landscaping worldwide, it has been listed as an invasive species in some countries, such as Australia. There, it poses a threat by outcompeting native vegetation and leading some plant species towards extinction. Controlling the spread of Fraxinus uhdei is crucial for conservation efforts, particularly in regions where it has become invasive outside its natural range.
The Shamel ash tree derives its common name "ash" from Old English, while its genus name comes from Latin. Interestingly, in both languages, the word meant "spear."
Tropical ash is well resistant to disease and is generally unlikely to be affected by illnesses. In terms of care, this plant is fairly low-maintenance. When grown outdoors it needs only minimal watering, and larger specimens normally do not require pruning. Smaller plants, however, should be pruned after they have finished blooming. Tropical ash is suitable for anyone with an outdoor area, such as a garden or a deck, and does not need extensive care experience.
How to keep Fraxinus Uhdei.
Light
The tropical ash does best with abundant sunlight, although it can tolerate environments with a moderate amount of shade. Native to sun-filled habitats, its best health and growth rely on substantial light exposure. With diminished light its growth may slow, while excessive light can lead to leaf burn.
Water
The Tropical ash thrives in humid, tropical environments and requires a balanced amount of water. To maintain its health, it should be watered every 1 to 2 weeks. As an evergreen tree, it retains its leaves throughout the year and needs consistent moisture, even during its dormant period.
Temperature
Tropical ash, native to warm climates, needs temperatures of 68 to 95 ℉ (20 to 35 ℃) to flourish. During colder periods, it may benefit from slight temperature adjustments to keep it within its preferred range.
Fertilizer
To encourage healthy growth, fertilize your Tropical ash in early spring. Consistent feeding boosts overall health, producing vigorous growth, greater tolerance of challenging conditions, and enhanced resistance to diseases and pests. Keep to a regular fertilization schedule for your Tropical ash to maintain vibrant, deeply colored foliage and a lush appearance.
Pruning
Tropical ash is a fast-growing tree that develops a thick canopy. To maintain its health and appearance, it is important to prune it properly. Focus on removing dead branches, thinning out crowded areas, and shaping the tree to ensure structural integrity. Ideally, this should be done in early spring. Regular pruning helps control the tree's size, strengthens its branches, reduces the risk of storm damage, and promotes healthy growth.
