Best Commercial Potting Mix for Tomatoes—Buying Guide
With the dozens of mixes out there, it’s essential to understand what is in potting soil to guarantee the most success in growing your tomatoes. Knowing the many terminologies used while discussing soil can assist you in deciding which organic potting soil to buy.
Potting Soil Types and Terms
We’ve covered a variety of the most frequent potting soil additives that may make or break the flavor and appearance of your tomatoes.
Soil pH
To keep tomato plants in a neutral range, the soil must be balanced. Soil pH ranges from 0 to 14, with tomatoes doing best at 6-6.8 pH. Soil that is too acidic will stunt a tomato’s growth, flowering, and fruit-bearing potential and lead to root rot and other issues.
Soil Amendment
A soil amendment is any item, such as those listed below, or even something as simple as crab meal, that is added to gardening soil to enhance its properties, such as nutrients, moisture retention, or acidity.
Sandy Loam
Sandy loam is a kind of soil composed of clay, silt, and sand. Since it drains properly, this is the best organic potting mix for growing tomatoes. When sandy loam is added to soil, it allows air and water to reach the roots more easily.
Clay soil
Clay soil has more clay than sand or silt. It is quite compact and not ideal for growing tomatoes or other fruit-bearing plants. Since clay is abundant in minerals, it is added to garden soil, but it does not allow enough water or air to reach root development on its own.
Acidic soil
Some plants, like tomato plants, grow well in soil with a slightly acidic pH. But, as previously said, tomatoes grow best in neutral soil.
Sphagnum/Peat Moss
Sphagnum and peat moss are two distinct materials that are often mixed for extra nutrients.
Sphagnum is a living moss gathered from the surface of bogs and marshes. The pH of sphagnum moss is neutral. The moss is then dried and sold alone or combined with other organic materials to aerate the soil.
Peat moss is dead moss harvested from the bottom of bogs and wetlands and is packed with nutrients and is similar to compost. Peat moss is rich in nutrients and might take hundreds or thousands of years to produce.
This substance raises the pH to a more acidic level. When combined with sandy soil, it aids in moisture retention. It improves soil aeration when combined with clay soil, resulting in more loose soil.
Earthworm castings
Earthworm castings, also known as vermicast, are the rich waste produced by earthworms. This nutrient-rich organic fertilizer not only improves soil fertility it also aerates potting mixes, thereby increasing drainage while at the same time improving moisture retention.
Forest Humus
Similar to human-made compost, forest humus is the rich dark topsoil found in forests. It is formed as a result of the decomposition of organic substances, such as leaves, insects, or bark.
This process is aided by earthworms and other organisms and contains essential nutrients for plants to grow. It helps to aerate the soil and minimize compaction, which enhances the flow of water and oxygen to the roots.
Coconut Coir
Coconut coir, a more sustainable alternative to peat moss, has comparable qualities as peat moss. It aerates garden soil, allowing it to drain while also increasing water retention. When applied to organic soil, this substance will balance the pH levels of mildly acidic soil.
Composted Pine Bark
Produced by leftover pine bark from the timber trade, composted pine bark is essentially composted wood shavings. This is the main element in potting soil.
Alfalfa meal
Alfalfa contributes vital elements to soil, including vitamin A, phosphate, nitrogen, and potassium. It usually comes in pellets that can easily be added to organic potting soil, including container plants or even raised beds.
Dolomite Lime
Dolomite lime is a fertilizer that supplies calcium magnesium carbonate while also balancing soil pH. This should only be used if no other organic fertilizers are used, such as those mentioned above, as too much dolomite lime can be detrimental to tomatoes since they love neutral soil.
