Buyer’s Guide – Best Soil for Tomatoes in Raised Beds

Growing plants in the raised beds is a nice idea as we all love the early season and fast growth which is tough in case of open crops. Choosing the best soil or medium for tomatoes or other plants is the first step for better growth and enhanced productivity. 

Here are the things which you need to consider before buying soil or potting mix for the raised beds or containers.  

Medium for growing tomatoes

Tomatoes can be grown in any kind of soil but the results in terms of fruits would be extremely different from those grown in native soil compared to one grown in fertilized granular soil.

Usually, native soil that is tough clay has poor drainage and forms muddy cakes which affect root growth in the negative and increase drought stress. 

On the other hand, a loam would make better soil for the raised beds with a reduction in drought stresses and increase of air spaces to help roots breathe and grow. For those who are unaware of loam, It is a blend of sand and silt with some clay maintaining an equal ratio of sand and silt.

Silt helps in better drainage while the sand keeps the composition granular and offers better aeration and reduces drought stress as well. The clay in the loam offers nutrients and compact texture to help roots stand and grow. The addition of fertilizers and potting mix to the loam makes it the perfect raised bed for both indoors and outdoors plantation. 

The pH is important

A suitable pH will allow the plants to grow fast and use all the nutrients efficiently as different chemical processes need a constant pH to keep working. In the case of tomatoes, the suitable pH ranges from 6- 6.8 which is slightly acidic. While buying soil or potting mix you need to check pH.

Moreover, before starting planting tomatoes you need to check soil pH if you are not using ready-made soil. In the case of highly acidic soil, lime is added to adjust the pH while the alkaline soil is fed with sulfur to lower the pH. 

Source of the Soil or Medium

An organic and natural soil or potting mix should be the priority. It helps in many ways, for example, safety for pets and kids, better growth, and less contamination of toxic chemicals in the fruits.

An inorganic fertilized soil may offer you quick results but is never a wise choice considering health issues and domestic use. 

Water Retention

The majority of these soils for the raised beds have an issue of getting dry too quickly which affects plants in the initial days. An ideal soil would be the one that can retain water at least more than 24 hours to fight drought and support root growth.

In addition to better retention, it should also allow these granules to make airspaces for roots to breathe, so the granular texture of the soil will serve both purposes very well, while a native clay or soil will fail in both. 

Know your soil composition before buying

Often people confuse dirt with the soil and after getting the order they are more confused about planting and installation.

Dirt needs extra soil to be added and then needs installation while the ready to use soil just needs installation straightaway. 

Sometimes the fertilized and concentrated soil is made for the loam to be mixed with but gardeners use it in concentrated form and burn the plants. So always make sure what composition you have got and then make the medium to grow your plants. 


If you are looking for something ready to be used for the raised bed, then we suggest Miracle-Gro increased bed soil which requires no mixing. On the other hand, if you have already established a medium but needs a concentrated supplement for nutritional values, then grab Miracle-Gro Organics Raised Bed Plant Nutrition Granules for natural resources of nutrients and enhanced productivity. 

Some of these packages are as heavy as 30-40 lb while some are just 3 lb so do your calculation and order the right quantity to avoid the additional cost of the shipment and mental stress. 

Happy Gardening and good luck!
