Potting soil contains all the vital nutrients in the right proportion. A good potting soil generally contains three main ingredients: composted tree bark, sphagnum peat moss, and perlite. The main function of these ingredients is to hold water and other ingredients.

Potting Soil Buyer’s Guide

There are many different types of potting soils available in the market. You should know what makes a good potting mix so that you can purchase the right product.

The best potting mix has a good drainage system, natural ingredients, excellent airflow, and the right nutrient proportion.

You should consider the following points while purchasing the potting soil mixes for growing vegetable plants.

Types Of Potting Soil

Potting soils have different types based on the types of plants that you can grow in them. But not all soil mixes are suitable for vegetables.

Therefore, it is important to know which kinds of potting mixes are available in the market so that you can pick a suitable vegetable potting soil.

All-Purpose Potting Soil

All-purpose potting soil is a well-rounded soil that can usually be used for both outdoor and indoor plants. For example, you can use it for houseplants, window boxes, and herbs, etc.

It may or may not have organic fertilizers. If the all-purpose potting soil contains fertilizers, then it may increase foliage production.

However, when growing vegetables, blossom development is more important than foliage production. Therefore, if you are interested in buying all-purpose mixes, then get the ones that do not have fertilizers.

Seed-Starting Potting Soil

Manufacturers develop seed-starting potting soils to support germination and the early development of seedlings. It encourages the growth of new plant roots and shoot systems. For this purpose, it is fluffy and light in weight.

A sterile environment is very important for the healthy growth of seedlings. Therefore, this mix is also sterilized to make sure the seedling does not develop fungal, bacterial, or viral diseases.

Plant Specific Potting Soil

A plant-specific potting soil has characteristics that are suitable for the growth of a particular plant. The manufacturers adjust the pH and ingredient level according to the plant’s basic needs.

For instance, if you are interested in growing potatoes, then this soil will have a balanced pH and nutrients that this specific plant needs for healthy vegetable growth.

Organic Potting Soil

As the name indicates, organic potting soil contains all the natural or organic ingredients.

Today, many gardeners prefer growing organic vegetables. For this purpose, they use organic soil.

It contains ingredients like organic matter, bone meal, earthworm castings, bat guano, alfalfa meal, etc., instead of chemical ingredients that have negative health effects.

Water Retention Ability

The best soil has excellent water retention ability. The key ingredient of the potting soil that absorbs and then retains water is Sphagnum peat moss.

However, some types of soil also have other ingredients, such as water-absorbing crystals that act as additional wetting agents.

Such crystals tend to absorb water when they are saturated. Then they release it slowly when the soil starts drying out. This way, they prevent water flooding and shortage.

Consider buying soil with these crystals only if the vegetable that you want to grow is very sensitive to water.

Ingredients Of The Potting Soil

Potting soils have a variety of ingredients that are required for the growth and development of healthy plants.

Most common ingredients include coconut fiber, wood chips, pine bark, and perlite. Each ingredient has its own function.

It also contains several essential nutrients in the right proportion. Unlike the plants growing outdoors in the ground, container plants have a restricted supply of nutrients.

Their nutrients decrease with time as they are absorbed by the potted plant. Therefore, you should keep adding natural fertilizers to make sure your vegetables are not nutrient deficient.

Fungal Or Mold Growth

Many potting mixes do not have anti-fungal ingredients; as a result, the fungus can develop in them and can cause fungal plant diseases.

If your vegetable is very sensitive to fungus, then try to buy soil with anti-fungal properties. Otherwise, you can prevent fungus growth by controlling moisture content and improving the airflow in the soil.

You can also buy anti-fungal sprays from the market and use them during the season when fungal infections occur more frequently.
