Mongolian oak

Mongolian oak (Quercus mongolica) plants should be watered deeply and thoroughly to encourage strong growth and root development. In the first few months after planting, they should be watered about once per week, providing 1-2 inches of water each time. During the warmer summer months, Mongolian oaks should be watered every 5-7 days and given about 1.5 inches of water each time as they tend to be more drought tolerant during these months. In the cooler autumn months, you can reduce the watering frequency to once every 10-14 days, giving 1-2 inches of water. Finally, during the winter months, you can reduce the watering frequency to once every 3-4 weeks, but make sure to water generously nonetheless.

Mongolian oak, also known as Quercus mongolica, typically thrives in full sun to partial shade. The amount of sunlight it needs depends on various factors including season, climate, and soil type. Generally, this species should receive at least 4 hours of direct sunlight a day in spring and summer, and indirect light or partial shade during autumn and winter. In hotter climates, it is best to provide the oak tree with added shade in the afternoon to avoid overheating.

Mongolian oaks should be pruned in early spring when growth is beginning, just before buds break. Pruning should be done lightly to open up the canopy and thin out crossing or overcrowded branches. It is important to not prune more than 20% of the total canopy, as this can permanently damage the plant. Cuts should be made close to the trunk to reduce the risk of new shoots growing from stubs. When pruning larger branches, it is important to make 3 clean cuts over several seasons to avoid shock and dieback. Mongolian oak can also be pruned during the summer months for shaping and training.
