How to Choose the Best Soil for Plum Trees

There are several considerations to keep in mind when choosing the best soil for plum trees. In general, there are four things that will determine which soil you choose.

The Type of Soil

Plum trees are fairly resilient plants and there are several different types of soil that they grow well in. As long as you choose one of these types of soil, you’re sure to have the best soil for plum trees.

Clay and silt

Any type of clay or silt soil is one of the best soils for plum trees. It should be fairly fine and made of small particles that get very sticky when you add water. This type of soil retains moisture extremely well, which is the main reason it’s a top choice for plum trees.

Loamy soil

Loamy soil is another excellent option for plum trees and is essentially a combination of things thrown together. It can consist of sand, clay, dirt, organic matter, and silt that is mixed together in a way that’s ideal for plum trees.

Sandy soil

Sandy soil is an excellent option if you live in areas with lots of dirt and little grass, such as southwestern states. As the name indicates, sandy soil consists mostly, if not entirely, of sand.

Acidity Level

Another thing to keep in mind when choosing the best soil for plum trees is the acidity level of the soil. Ideally, plum trees should be planted in soil with a pH level of between 60 and 6.8, with 6.4 being perfect. Soil with this pH level is lightly acidic, which means it isn’t too harsh for your plum tree to handle.


One of the main things to keep in mind when choosing the best soil for plum trees is how well it drains. It’s imperative that plum trees get planted in soil that drains well but holds onto moisture when necessary. The reason drainage is important is that plum trees need lots of moisture. However, holding onto this moisture for too long could lead to disease for your trees, so drainage is crucial.


There’s a surprisingly vast price difference when it comes to the best soil for plum trees. You can spend anywhere between $10 and $60 for the right soil and it’s entirely up to you how much time and money you want to invest into your project. The more expensive soil options are usually organic and have fertilizer or organic material added to them which gives your plum trees the best chance at success.

Wrapping Up the Best Soil for Plum Trees

As you can see, there are plenty of great options when it comes to the best soil for plum trees. Plum trees are somewhat demanding when it comes to drainage and moisture retention, but they’re very forgiving otherwise. Therefore, while plum trees will definitely stretch you in terms of testing your gardening skills, they’re one of the most rewarding plants you can grow around your home.
