watering

English oak needs to be watered deeply and infrequently. It should be watered thoroughly and allowed to dry out between waterings. During the summer growing season, the English oak should be given 1-1.5 inches of water every 2 weeks if the soil has had time to dry out between waterings. During the cooler months, the English oak should receive no more than 1 inch of water per month. It is important to note that English oaks should never be left in standing water. Over-watering can cause root rot and other detrimental diseases in the plant.

sunlight

English oak (Quercus robur 'Concordia') thrives with at least 5 hours of direct sunlight every day. This species does well with full sun in the morning, or early afternoon, and can tolerate partial shade in the evening for more extreme climates. It is important to note that it requires more shade during the hottest months of the year to ensure optimal growth. For best results, the English oak should get 8 to 10 hours of direct sunlight, especially during the summer months.

pruning

English oak (Quercus robur 'Concordia') should be pruned in late winter or early spring when the tree is still dormant. The goal of pruning an English oak should be to create a strong structure, remove dead or diseased branches, and open up the canopy to promote air circulation and light penetration. Pruning should be done gradually and judiciously over several years so as not to shock the tree. This species of oak should get light pruning each year, with heavier pruning every 3 to 5 years.
