How to pick the best soil for tomatoes?

We can’t emphasize the importance of dedicating enough time to picking a suitable potting mix. That includes reading soil for tomatoes reviews but also learning about the crucial features of these packs. What content should be added to the mixture? Do you need a small pack or a large bag because you want to be a big-scale grower? How do indoor or outdoor growing plans affect your tomato soil selection? All these are questions we aim to answer below. We listed the crucial factors for picking a suitable potting mix, so make sure to get familiar with all the details before choosing a soil!

Mix content

The ingredients included in the blend are the first thing you want to consider when choosing soil for tomatoes. Many formulas have a long list of components from various sources, such as the sea and the earth. Others focus on a single main ingredient, such as the Burpee Natural & Organic Premium Potting Mix, which is eco-friendly and contains coconut coir as the formula’s base.

Earthworm castings, perlite, pumice, and peat moss are frequent additions to potting soil formulas. You will also find fertilizer, wetting agents, or beneficial bacteria and microorganisms. The task of each compound is to promote optimal plant growth and development.

It is equally important that the formula doesn’t contain a vast portion of wood sticks and other residues, such as plastic. These compromise the soil quality and could affect plant development.

Apart from pure soil, you can also consider amendments, such as the Original Living Soil Concentrate. Their task is to be added to the potting mix to promote its properties.

Pack size

10 Best Soil Mixes for Tomatoes – Rich Harvest Guaranteed!

Tomato soils come in different packs. The amount in a single bag is determined by volume and measured in quarts. The packaging varies from four to 12 quarts or larger. Many products allow you to pick between multiple bag sizes, such as the Espoma 8-Quart Organic Potting Mix.

If you are a newbie to the tomato growing industry or purchase the soil for the first time, our advice is to start with a small bag. Once you confirm the mixture is the right choice, you can order bigger sizes if available.

While you are considering the pack size, make sure to take the price into account, too. The cost of tomato plant soils varies on the bag size. Affordable choices might not require paying more than $15 or so, but premium options could cost $25 or more.

It is critical to ensure you feel the soil provides plenty of bang for the buck. Whether that will be with the provided quantity or quality, it is up to you to decide.

Soil for indoor or outdoor use?

Before you can pick a soil for tomato plants, consider how you plan to grow them. Do you have the pots ready for indoor growth? Or you have a large backyard to utilize for planting tomatoes? Those specifics will determine which soil you need. For example, the Proven Winners Premium All Purpose Potting Soil is great for outdoor use. But if you plan on using the containers, you want to pick accordingly.

Tomatoes might require plenty of space per plant, which is why outdoor use might be a smart move. If you pick indoor growth, you might be limited to the space available. That being said, it might not be possible to use more than several pots. Large-scale growers could feel like they need more space, and that can be secured in a garden.

pH level

The pH level determines the acidity of the soil. The soils could be acidic or alkaline. When it comes to tomatoes, they appreciate soils that are a bit acidic. That means their levels should be from 6.0 to 7.0. That is why you can benefit from mixes that clearly specify their pH level, such as the Fox Farm Ocean Forest Potting Soil.

That doesn’t mean you can’t use soils that are more acidic or alkaline. If the level is higher than the specified, adding a sulfur component can lower it quickly. Alternatively, lime is the method of increasing pH levels in the potting soil.

Measuring the pH properties of your tomato soil mix requires a simple test kit. It is affordable, and you can acquire it at a local gardening store.

Overall quality

Many of the above-mentioned features could affect the overall quality of your soil mix for tomatoes. The first thing to consider is the capability of the soil to feed the plants. Many formulas are loaded with nutrients that can feed your tomatoes for up to six months, such as the Miracle-Gro Expand ‘N Gro Concentrated Planting Mix.

The next thing to consider is the capability to retain moisture. These properties can play an essential role in securing optimal water delivery to your plant. You want to check the porosity of your soil for tomatoes.

The porosity determines how well the potting mixture retains water. The level of porosity marks the pores, which are gaps between the soil particles. Their task is to ensure both water and air can go through and reach the root. That can be crucial for optimal plant development and securing adequate growth conditions.

FAQ

The answer varies depending on the tomatoes you are planting. If you are planning to use containers, choose compact and small tomatoes. They can reach a width of about two feet, but they won’t grow particularly high in size. Most tomato types, however, require more space. The plant’s roots can become as much as six inches wide. That is why staking the roots is recommended to ensure optimal growth conditions. While you are planting tomatoes into the soil, try to put two-thirds of the entire plant under it. The only parts above the surface should be the leaves. Root development is vital for tomatoes, which is why this is the optimal way of planting them.

A loamy tomato soil includes a combination of silt and sand with a small portion of clay. Each of these elements is added for a reason. The soil can compact easily because of the silt, which acts as sediment. Also, the manufacturers include sand to promote aeration and optimize drainage. The addition of clay guarantees the plant will have sufficient nutrients. It also helps to combine sand and silt. Remember that you should ensure there is an approximately equal amount of silt and sand, and they should make most of the potting mix. That secures the ideal component balance to promote tomato growth.

It is essential that the seedlings have sufficient space to branch out, which is why thinning is an option to consider at some point. Tomatoes require plenty of light. That could include sunlight, but you can also use an artificial source to ensure at least 15 hours of light daily. Watering depends on location and tomato type. Seedlings need a tiny portion of water since airflow is critical for their development. You can consider watering tomatoes every day once they develop. Try to decide based on the temperature. The experts estimate that tomatoes grown in the garden need approximately two inches of water weekly.

Our Verdict

At the end of our round-up, let us remind you that the FoxFarm Ocean Forest Potting Soil remains our top pick. The premium pack supports optimal plant growth and development and has a long list of useful nutrients for tomatoes. That includes components from the earth and sea, such as earthworm castings and bat guano.

The Burpee Natural & Organic Premium Potting Mix is great for those looking for an eco-friendly and organic tomato soil. Based on coconut coir, it ensures optimal moisture control and can feed your plants for months. It is also approved by OMRI for organic use, which means it has an official certificate.

The Espoma 8-Quart Organic Potting Mix is another exceptional candidate to become the best soil for tomatoes. It is available in multiple sizes and is an excellent pick for growing potted plants.

We hope that our reviews helped you to find your favorite potting soil. And remember, only a suitable potting mix improves the odds of securing optimal conditions for tomato growth.
