Netleaf oak (Quercus rugosa)

Netleaf oak

In the wild, netleaf oak (Quercus rugosa) is an exceedingly rare species. You usually only find it in two locations, both in the United States: on Mount Emory in Big Bend National Park and on Mount Livermore in west Texas. Even though it’s rare, that doesn’t mean it can't be cultivated. It loves direct sunlight and reasonably moist soil.

Care Guide for Netleaf oak

Every 2-3 weeks

Water

Full sun

Sunlight

15 - 35 ℃

Ideal Temperature

Water: Netleaf oak prefers conditions resembling its native habitat, enduring dry periods with minimal watering after establishment. Water every 2-3 weeks with deep soaks for root growth. As a deciduous species, its water needs lessen when shedding leaves prior to dormancy, benefiting from natural rainfall but needing irrigation in extended droughts.

Fertilize: Netleaf oak requires balanced fertilizer (10-10-10) biannually in spring and fall and a high-nitrogen formula during early growth for foliage. Regular feeding boosts vigor and flowering, but avoid overfeeding. Adjust rates for young trees and water thoroughly post-fertilization for nutrient absorption.

Pruning: Pruning netleaf oak in late winter enhances growth by removing dead or diseased branches and thinning the crown for better air circulation and sunlight. Maintain a clear central leader for structural integrity, and avoid excessive pruning to reduce stress, promoting longevity and resilience.

Propagation: Netleaf oak thrives in diverse conditions and is best propagated using semi-hardwood cuttings during active growth. Ensure cuttings have leaves, remove lower foliage to avoid rot, and dip in rooting hormone to promote root growth. Use well-draining soil and maintain consistent moisture for successful establishment.
