The Burr Oak (Quercus macrocarpa) is one of the largest and most majestic native oaks in North America, with a broad, spreading canopy that can shade an entire yard. Extremely tough, long-lived, and well-adapted to alkaline soils, it’s an outstanding choice for large San Antonio properties. Alfaro Tree Sales has been growing Burr Oaks at our 40-acre Atascosa nursery since 1976.
Burr Oaks develop enormous spreading canopies — often 60–80 feet wide at maturity — making them one of the best shade trees available for large properties, ranches, and estates in the San Antonio area.
Two SA shade giants compared side by side.
Expected height after planting a 4” caliper tree (16–20 ft at install).
Deep water 2–3×/week during the first growing season. After establishment, supplemental water only during extended drought.
Excellent in SA’s alkaline soils. No amendments needed. A slow-release fertilizer in spring after year 2 supports growth.
Structural pruning when young to develop a strong central leader. Prune in mid-winter only. Minimal pruning needed at maturity.
October through March. Plan for the tree’s massive mature size — plant at least 30 ft from structures.

Burr Oaks grow 1–2 feet per year, which is moderate. They’re a long-term investment that rewards patience with a massive, majestic canopy.
Very large — 60–80 ft tall with an equal or wider canopy spread at maturity. They need plenty of space and should be planted away from structures.
Yes, extremely. Once established, Burr Oaks have deep taproots that access groundwater, making them one of the most drought-tolerant oaks for San Antonio.
Burr Oaks are in the white oak family and show good resistance to oak wilt, though not as resistant as Monterrey Oaks. Still, they’re a much safer choice than Live Oaks or Red Oaks.
October through March is ideal. Our team plants year-round with proper watering protocols for summer installs.
