How To Grow A Walnut Tree In A Container?

A great way to grow a tree in a small space is by using a container. Containers are very useful for growing small plants like trees because they are very easy to transport. It also helps you to maintain the same growing environment that the plant would normally receive in its natural habitat.

Containers are also very easy to clean because all of the dirt and nutrients are contained inside. Plastic containers are also more secure than a clay pot that could fall and break if you’re moving the plant around. With this guide, you will learn how to grow a walnut tree in a container.

Choose the right pot/container

The right size pot/container is important, as it should be able to hold enough water and provide a spacious area for the tree to grow.

Prepare your potting mix

Before planting your walnut tree, you need to prepare a soil mix. The first step is to mix some organic compost with the soil. You want to mix about half of the compost into the soil.

Mix it well so that the compost is mixed into the soil. If you don’t have any compost, you can buy it at your local garden center. Add sand to your soil mixture.

Next, add sand to the mixture. This will help keep your soil from drying out when the weather gets hot and dry. Sand also helps absorb water. It also prevents the soil from becoming compacted.

Add peat moss to your soil mix. Now you can add some peat moss to your soil mix. Peat moss is an organic product that has many uses. It helps to hold moisture in your soil. It also helps retain nutrients in your soil. Mix all of this together.

Plant your tree

Remove the tree from its pot and place it into the hole you have prepared. You want to dig a hole for the tree as big as the root ball. If you are planting more than one walnut tree, then you need to dig a hole for each tree.

When you plant the trees, you will need to make sure the hole you dug is deep enough for the roots. The roots should go down about 6 inches into the ground. If the hole is too shallow, the roots may not grow properly.

Next, you want to put a small amount of the soil mix into the hole. This will keep the roots moist as they grow. Make sure that the trunk of the tree is in the center of the hole. The roots should be coming out of the bottom of the tree.

Now, water your newly planted tree

Watering the tree at this time will help the tree get established in its new location. Growing trees is enjoyable and brings along many benefits to our environment.


Use a hose to water your tree. This will help your tree establish quickly. If you are planting a tree in an area that has already been paved, consider using a rubber mat. These mats will keep the soil from being compacted, which will make it easier for your tree to grow.


It is evident that how to grow a walnut tree in a container is the most challenging task. There are many factors that influence the growth of a walnut tree. Among all these factors, soil quality is the most important factor because it influences root growth and development. It should be noted that the soil must be very good for the roots to grow.

The soil should have good drainage and high organic matter content. Watering this tree is also critical in its early stages.  The soil should not be too wet as it will cause the roots to rot and also it should not be too dry because it will make the tree prone to pest attack. If you want to grow walnut trees in containers you should make sure to take care of all these points.

Frequently Asked Questions

Can you grow a black walnut tree in a container?

Yes, but it will not be as big and healthy. Black walnut trees are very drought-tolerant, so if you’re planning to plant your black walnut in a pot, you should plan on watering it regularly. We recommend using a soaker hose or automatic drip irrigation.  

How many years does it take to grow a walnut tree?

It depends on the variety. For example, our 'Blackjack' black walnut trees are ready for harvest in 2.5 years, and 'Red Diamond' black walnuts are ready in 4 years.

How do I keep my walnut tree small?

If you want a small black walnut tree, we suggest planting it in a large container that has been prepared with a substrate of peat moss or sand. The soil mixture should be moistened to retain water. The soil mixture should be kept moist until the tree begins to grow. It should not be allowed to dry out.  You can prune your walnut tree to keep it small and manageable. 

Can you grow a walnut tree from store-bought walnuts?

Yes, but they will not produce fruit. We recommend planting the seeds directly into the ground. The height of our walnut trees is usually between 30 and 40 feet tall.
