Sapling And Soil

The first step to creating a Red oak bonsai is collecting saplings. Red oak trees are not rare in most places, there should be online sites that sell them.

The soil also should be slightly acidic because that is what they prefer in nature. Although Red oak is a strong tree and should be able to grow in any soil. However, it is best to create the soil that imitates its natural environment.


The sapling should be watered on a daily basis but do not overdo it. The best way to check if your tree needs water is to check with your fingers. Check the dampness of the soil, if it is too dry your plant needs water. Another way to check is by lifting up the pot, if it’s light you will understand it needs water.


The trees need full sun and should be placed outside for most of the day. Although as a sapling, keeping them in the shade in the afternoon is a good idea. They can survive most weather when they are fully grown. They are trees that love to be outside and as bonsai that does not change. The trees should be in a place that is 3 to 4 ft high . Make sure they receive full sunlight and even in winter they should be kept outside.

Cutting And Trimming

The trees grow fast and they should be trimmed accordingly. The top growth should be trimmed every month to make sure it does not grow too big. You can use a hand trimmer. Most lower branches should also be trimmed regularly. The Red oak is a strong tree so do not be afraid about trimming branches or the top growth. If you are too laxed with trimming it might grow too big for a pot. So, it is best to keep it under constant observation.

Wiring And Styling

The styling can be done on young trees but the branches are extremely brittle at that age. The best time to do wiring is after 2 years. Regular trimming is the safe bet before that. Although if you are an expert and understand the art you can style a young Red oak bonsai. The styling and training depend on individual preference, so take the route that suits you best.


Repotting for a bonsai is an essential part. The Red oak should be repotted every two years. While repotting the tree, trim the roots that are thick and strong. These roots are not needed and will grow out of the pot. The fine thin roots that are the majority are enough for your tree to survive. So, cut the roots that are 1 to 1.5 inches thick but keep the fine, thin roots intact. Also, move your tree to a bigger pot if you want it to have more freedom.

Pests And Fungi

The Red oak trees are hardy trees but they also can be infected by pests or fungi. The Canker pathogen has been attacking Red oaks all over Northern America. They cause leaf browning, bark cracking, and bleeding. The sign of a canker is visible at an early stage so removing the infected branch can make the tree safe.

The other danger is the two kinds of fungi. They are Phytophthora cinnamomi and Phytophthora ramorum, they attack the trunks and cause red black cankers. The use of market fungicides is enough or you can use baking soda as an organic fungicide.


The Red oak is one of the most beautiful trees in nature and as bonsai, if they are well maintained can be brought up in your small backyard. The trees are tough and can survive most climates and soil. So, do not be worried about your Red oak bonsai, just keep it under constant observation. The project might seem ambiguous at first but it is not. They are excellent and majestic trees in nature and as a bonsai that does not change.
