| Height, feet | 40 to 90 where planted; up to 120 in its native stands |
| Spread, feet | Up to 60 |
| Zones | 6 to 9 |

| First crop | 20 or more years (none under 20 in one survey; crops grew until about 80) |
| Pollination | Needs a second, unrelated tree. The flowers are wind pollinated, and an acorn crop wants another oak nearby, since oaks seldom set acorns with their own pollen. |
| Lifespan | Lives up to 500 years. |
| Planting season | Spring. The NRCS plant guide moves container seedlings in spring; in a Washington trial, most seedlings planted from November to March lived, and most planted in September died. |

What our tools say
How fast it grows and how big it gets, by site Whether it suits your zone, sun and soil How far from a house, wires and a septic field What grows with it in the wild and in a yard When to plant it where you live When it flowers and fruits, month by month How to sow its seed, with dates for your place How many to plant for a crop of seed Whether one you have can be moved, and what the move takes How old one is, from its trunk How a big one scores against the champion trees
