In orcharding is very popular, valued especially for fast growth and distinctive autumn color of leaves. It is used as a solitaire or in groups in parks, but also in alleys and alleyways in wide streets, but here it may suffer from a corolla. It is also sometimes used in forest stands and reclamation. |
| Habitat |
Not demanding on the habitat, growing in open positions, on a level and on a slope. It is best suited to deep, permeable soils, but it also grows on sandy and gravel soils. It is resistant to frost and exhalates. |

| Note |
Due to the inclination of red oak to weed our surroundings, in recent years planting in forests and forest parks is somewhat problematic. Red oak spreads uncontrollably at the expense of domestic woods. About 10-12 years ago it was necessary to solve this problem at Pastýřské stěna by cutting off about 90% of its specimens. The tree where you stand is one of the last. There should be no problem in well-kept gardens and parks, where leaves are continuously dug up. The largest specimens from Europe are from Belgium (kasteel d´Aertrycke obv. 803cm) England (Marston House, ob. 750cm), Germany (Karlsruhe ob. 620cm). Large specimens also grow in the Pillnitz Castle Park near Dresden (570cm), or in the Tovarníky u Topoľčany (546cm, v. 29m).
