Scientific / Botanical Aspects
In botanical terms, the Northern Red Oak belongs to the Fagaceae family, the genus Quercus and the species Rubra, hence its scientific (or botanical) name Quercus Rubra (KWER-kus ROO-bruh).
As with other Quercus’s, the Northern Red Oak is a deciduous plant, which means it will shed its leaves annually once autumn comes.
The Northern Red Oak is a plant native to Eastern North America and Eastern Canada. This is why the Quercus Rubra is used to growing in specific regions such as the states in Southeast, Northeast, and the Southwest of the United States.
Knowing your plant’s native region is very useful, as it can give you tips on which environment is best for your Northern Red Oak. If you keep it in mind, you can try to replicate these conditions at home, and you’ll likely end with a healthier plant.
With this in mind, the Quercus Rubra will be most used to the heat zones in the 5 – 9 region, as the plant hardiness level falls between 4a, 4b, 5b, 5a, 6a, 6b, 7a, 7b, 8b, 8a and the ideal climate zone is between 1, 1A, 1B, 2, 2A, 2B, 3, 3A, 3B, 4, 5, 6, 7, 8, 9, 10, 14, 15, 16, 17, 18, 19, 20, 21.

As a rule of thumb, you should remember to keep your Northern Red Oak in soil with moist but well-draining to well draining characteristics, as these will guarantee the right conditions for your plant to grow and thrive.
When you consider this, this is why you should aim to choose soil that has good drainage, and moist properties to keep the right moisture levels at all times.
But, if you want a ‘one-size-fits-all’ solution to watering your Northern Red Oak then you should consider the famous ‘finger’ test. To perform this test, you just need to put your finger in your plant’s soil and determine if it’s moist or not. If it is, then don’t water; if it isn’t, then please do. In any case, this test will allow you to know if your Northern Red Oak needs or does not need water, every time.
As mentioned earlier, the Northern Red Oak prefers to have soil with good drainage, and moist properties at all times, reason why you need to make the soil mix out of sand, loam, and clay.
