Which Is The Best Soil for Tomatoes in Containers?

While tomatoes aren’t very picky when it comes to soils, below are some of the characteristics of the ideal potting mix for growing tomatoes in containers.

Texture

Tomatoes thrive better in loose soil, preferably loamy soil. The soil needs to be well-drained and be adequately aerated. Compact soil like clay can inhibit growth, while extremely loose soil will not hold water long enough to support the growth of tomatoes.

 PH

Tomatoes prefer a pH between 5.5 and 7.5. As such, you need to test the PH of the soil and make the necessary amendments. For instance, to make the soil less acidic, you can add lime. And to make the soil more acidic, you can add compost, pine needles, or sulfur.

Nutrients

Tomatoes are heavy feeders. So, above all else, make sure the potting soil has lots of nutrients.

Some of the ingredients that nutrient-rich soil should contain include compost, alfalfa, and fishbone meal. Also, make sure the soil contains enough phosphorus, potassium, and calcium.

Now that you know the best type of soil for potted tomatoes, there are two ways you can access these soils:

  1. Make your own potting soil
  2. Buy bagged potting soil – This is the best option for those who are not good at DIYing. Or you don’t have the time to make your own or you just want to save money.

How to Make Your Own Potting Soil for Tomatoes

DIY can be fun and you get to control the ingredients to add to the mix. It also saves you a few bucks.

If you choose to go the DIY route, below are some of the items you’ll need:

The Process

One process that has worked for me is mixing all the ingredients above in a 1:1:1 ratio. That means:

  • 1 part of organic materials for nutrients, drainage, and aeration. (Preferably garden soil, compost, or commercial potting soil)
  • 1 part inorganic materials for improving drainage (perlite or sand).
  • 1 part inorganic materials to prevent compaction (peat moss and or coir)

Once you have all the ingredients, put them in a large bucket for efficient mixing. Start with the peat moss or coir, which needs to be pre-soaked.

The best ratio is 2:1 for peat moss and water. Once it’s soaked, add all the other ingredients as mentioned above.

It’s also essential to add slow-release fertilizer, especially if you will be using the potting mix right away. If not, make sure you add some when planting the tomato plants.

NOTE: Be careful when using garden soil or compost since it’s dense and may contain contaminants. If possible, you can sterilize it by baking the soil at temperatures ranging from 180 to 210 degrees Fahrenheit for 45 minutes.

Things to Consider When Choosing Potting Soil for Growing Tomatoes in Containers

As mentioned earlier, there are varieties of potting soils. This makes choosing the best a daunting task, especially for a new gardener.

The plants you intend to grow are the primary guide to suitable potting soil.

Also, the quality of the soil matters because some plants will thrive in loamy soil while others in clay. Here is a guide to help you choose a potting soil that will work for your potted tomatoes.

Location of Plants and Moisture Retention

The location where you want your plants to grow is the number one factor to consider.

Are your plants going to be under a shade or full sun? You will need light potting soil if you grow them under a shade because evaporation will be limited.

On the other hand, if you’re growing them under full sun, you will need a denser tomato potting soil so that it can hold water for long.

If you are too busy to water your plants daily, you might need potting soil that features gel granules because they will help them hold water for a longer period of time.

Organic Vs. Inorganic

Potting soil can either be organic or nonorganic. Organic soils are the best for nutrients, while inorganic is the best for soil amendment.

However, they are both good for potted plants. The difference is that inorganic mixes contain fertilizers while organic ones are natural with various types of nutrients.

You can also mix organic and inorganic ingredients, as explained earlier, for a better potting mix.

Ingredients

This is another factor that should guide you to the right mix. Potting soil contains several ingredients, including peat moss, perlite, vermiculite, and organic ingredients.

On the other hand, some don’t include organic materials. The ones that have vermiculite hold water for long, while those with perlite are great in drainage.

Additionally, others have lime which helps in balancing the pH level of the potting soil.
