Quercus fusiformis 10-30cm

Quercus fusiformis, commonly known as the Texas live oak, escarpment live oak, or plateau oak, is a semi-evergreen oak tree native to the south-central United States, particularly Texas, and into northeastern Mexico. It is valued for its hardiness, longevity, and aesthetic appeal, especially in landscapes designed to reflect the natural beauty of the Texan scenery. Here's a detailed description and some tips for its cultivation.

Description

• Leaves: The leaves of Quercus fusiformis are thick, leathery, and dark green, with a paler underside. They are typically 2 to 4 inches long and have a slightly wavy margin, sometimes with a few shallow lobes or teeth.
• Bark: The bark is dark gray to black, deeply furrowed, and rugged, providing a striking texture to the tree's appearance.
• Acorns: The acorns are one of its notable features, being somewhat elongated or fusiform (hence the species name 'fusiformis'), about 1 inch long, and enclosed in a scaly cup. They mature in one season and serve as a food source for wildlife.
• Size and Form: Quercus fusiformis can reach heights of 30 to 50 feet, with a broad, spreading canopy that can be as wide or wider. It is often multi-trunked, with a dense, rounded to oval shape.
• Habitat: It is adapted to a variety of soils but prefers well-drained, limestone-based sites. It is drought-tolerant once established and can be found in various habitats, from open plains to rocky hillsides.

Cultivation Tips

• Planting Location: Choose a site with full sun to partial shade. Texas live oak can adapt to a wide range of soil types but thrives in alkaline, well-drained soils. Ensure there's enough space for its wide, spreading canopy.
• Watering: It is drought-tolerant once established but will benefit from regular watering during the first few years after planting. Water deeply to encourage deep root development.
• Pruning: Prune in late winter to early spring to remove any dead, diseased, or crossing branches and to shape the tree as desired. Avoid excessive pruning.
• Mulching: Apply a layer of organic mulch around the base of the tree to conserve soil moisture, regulate soil temperature, and reduce weed competition. Keep the mulch away from the trunk to prevent rot.
• Fertilization: Generally, Quercus fusiformis does not require frequent fertilization. If growth seems slow or the foliage lacks vigor, a balanced, slow-release fertilizer applied in early spring can be beneficial.
• Pests/Diseases: Monitor for common oak pests and diseases, such as oak wilt, which can be a serious concern for Texas oaks. Implementing proper cultural practices can reduce the risk of problems.

Quercus fusiformis is a resilient and attractive oak that, once established, requires minimal care, making it an excellent choice for xeriscaping, naturalistic landscapes, and as a shade tree in both urban and rural settings. Its ability to withstand drought and poor soil conditions, along with its majestic appearance, makes it a valuable addition to any Texas garden or landscape.
