Oakland Holly is a versatile evergreen shrub, valued for its consistent greenery and ease of care. Its low-maintenance nature makes it a popular choice for diverse landscapes.
Understanding Oakland Holly
Oakland Holly (Ilex hybrid ‘Magland’ PP14417) is an evergreen shrub known for its dense, pyramidal growth. Its glossy, dark green leaves are uniquely shaped like oak leaves, with serrated or lobed edges instead of typical holly spines. This hybrid reaches 15 to 20 feet tall and 12 to 15 feet wide, growing moderately at 12 to 24 inches per year.
It produces abundant, bright red to orange-red berries in fall and winter. These berries add visual interest and feed birds. Unlike many hollies, Oakland Holly is self-pollinating, so a single plant produces berries without a separate male pollinator.
Why Oakland Holly Excels in Texas
Oakland Holly is well-suited for the Texas climate, thriving across USDA Hardiness Zones 6 through 9. It tolerates intense Texas heat and humidity. Once established, this holly is drought-resistant, a valuable trait for dry periods.
This plant adapts to a wide range of Texas soil types, including clay, loam, sandy, and silty compositions, though it performs best in well-drained, slightly acidic conditions. Its evergreen nature provides year-round greenery. It is also resistant to common Texas pests and diseases, making it low-maintenance and resilient.
Cultivating Oakland Holly in Texas
Cultivating Oakland Holly in Texas requires proper site selection. Choose locations with full sun to partial shade; in intense summer heat, afternoon shade protects foliage from scorch. Dig a hole two to three times wider than the root ball, placing the top of the root ball one to two inches above ground level to prevent root rot. Backfill carefully, and for privacy screens or hedges, space plants six to eight feet apart for mature growth.
Watering is crucial during the first one to two years after planting. Deep, consistent irrigation, about one to two times per week, encourages strong root development. Once established, Oakland Holly becomes more drought-tolerant, requiring deep watering every two to four weeks, allowing the soil to dry out between applications. Apply a two to four-inch layer of organic mulch around the base to retain soil moisture and regulate temperature, keeping it a few inches from the trunk.
Its natural pyramidal form means Oakland Holly requires minimal pruning. Prune for density or aesthetics in early spring before new growth or after flowering. Fertilize annually in early spring with a slow-release, balanced fertilizer or one for acid-loving plants. A soil test can determine nutrient needs and if amendments like elemental sulfur are required to maintain a slightly acidic pH.
Addressing Common Issues in Texas
While generally robust, Oakland Holly can face issues in Texas. Overwatering, especially in heavy Texas clay soils, can cause root rot from poor drainage. Ensure adequate drainage by mounding soil or incorporating organic matter before planting.
Extreme heat and insufficient moisture can cause leaf scorch, where edges turn brown. Avoid this with supplemental deep watering during dry spells, and protect younger plants from intense afternoon sun. Chlorosis, or yellowing leaves between veins, indicates a soil pH issue. If Texas soils are too alkaline, apply chelated iron or elemental sulfur to correct the imbalance and restore leaf color.
