The second most important thing to look for in potting soil is fertilizer. While you can add fertilizer to your plants at any time, it’s best to do so when first potting your plant.
This will ensure the nutrients are absorbed properly by the roots of your plant, and that they don’t get washed away by watering or rain before they’ve had a chance to take hold.

The most important factor in potting soil is the type of soil. The type of soil determines how well it retains nutrients and water, which are necessary for your plants to grow. There are three different types of soil: sand, silt and clay.
Sand has the largest particle size; it is coarse and gritty. Silt is a finer grain texture than sand with small particles that aren’t easily seen with the naked eye. It also has a somewhat smooth texture when dry but can become gritty when wetted down due to its fine grain size.
Clay particles are extremely fine in size (the smallest) and have a tight bond between them that makes them sticky when wetted down or moistened by rainwater or irrigation systems like drip lines or sprinklers;
they’re also known as clods because they tend to stick together instead of breaking apart easily like sands do (which allows water from irrigation systems – drip lines & sprinklers – such as rainfall simply wash away before reaching roots).
Compost is an easy way to add nutrients and beneficial microbes, which are essential for healthy soil.
It also helps improve aeration and drainage. When you purchase compost, be sure to find out what it has been made from—some composts may contain pesticides or other chemicals that will harm your plants.

Peat moss is the most common ingredient in potting soil. It’s a renewable resource, and it contains organic matter that helps hold water.
But it’s not recommended for seed starting mixes because peat moss doesn’t have much nutritional value for young plants.
Perlite and Vermiculite
Perlite and Vermiculite are both lightweight, natural materials that are used to lighten the weight of potting soil.
Perlite is a mineral that is heated and expanded to create a white, lightweight substance with a sponge-like texture.
Vermiculite is another mineral that expands when heated into a grayish-brown material with good aeration qualities. Both perlite and vermiculite can be mixed into potting soils at rates of 10 percent to 20 percent by volume (or about two parts perlite or vermiculite for every 10 parts soil).
pH is the measure of acidity or alkalinity in your soil.
The range for soil pH is from 0 to 14. A pH reading of 7.0 represents neutral conditions, with anything below 7 being acidic and anything above being alkaline.
You can easily test the pH of your potting soil with a kit available at most garden centers or online retailers (see Resources).
If you are using store-bought potting mix, check out the bag to see if it contains any amendments that will affect your results such as lime or fertilizer; if so, take this into account when testing the soil’s acidity level.
If after testing you discover that your potting mix’s pH levels fall outside of 5–7 range, there are easy ways to adjust them: add ground limestone where needed for more basic soils (alkaline) or use an acidic compost mix for more acidic soils like peat moss mixed with composted pine bark mulch—or simply buy some fresh potting mix from a local nursery!

Drainage is important for the health of your plants. If water cannot drain from the soil, it will pool and cause root rot.
Drainage can be achieved by mixing sand, gravel or crushed rock into the soil. Alternatively, you can choose to use a pot with holes in it instead of using potting mix that has drainage holes built in.
Moisture retention is another important factor to look for in potting soil. It’s important to note that having the ability to retain moisture is not the same as having too much moisture in the potting soil.
The ideal situation is for your potting soil to be able to retain enough water so that it doesn’t drain out of your pots and onto your floor, but not so much that it gets soggy and difficult for plants to grow.

Aeration is important for both drainage and the health of your plants. The right amount of aeration in potting soil makes it easy for water to pass through the potting mix, preventing waterlogged roots that can lead to root rot or fungal diseases.
Aerated soil also allows air pockets between particles so oxygen can reach the roots, which promotes good root development and helps prevent root diseases as well.
If you’re buying a bag of potting soil at a local garden center or home improvement store, look for one with large crumbs or pieces of peat moss instead of fine dust — these will help provide better drainage and more aeration than finer materials.
If you make your own compost from kitchen scraps and yard waste (a great idea), be sure to add coarse sand or perlite to help improve drainage and aeration without compromising any nutrients in the compost itself!

Weed & Disease Control
Weed control – Control weeds by using a mulch, or apply pre-emergent herbicides to prevent weeds from germinating.
If you have already allowed weeds to germinate, you can use post-emergent herbicides to kill them. In some cases, systemic herbicides may be used to control weed growth after it has begun in the soil.
Disease control – Apply beneficial fungi and bacteria (such as mycorrhizae) that are naturally present in potting mixes that are low in organic matter; this helps plants fight off diseases more effectively.

So, now you know what to look for when buying potting soil. You can make your own compost, use peat moss instead of compost if you need aeration and drainage in your mix, or choose a commercial mix with more organic ingredients like vermiculite and perlite.

What is potting soil?
Potting soil, also known as potting mix, is a specially formulated soil designed for growing plants in containers or pots. It typically contains a mixture of organic matter, minerals, and nutrients to provide an ideal environment for plant growth.
What is the difference between garden soil and potting soil?
Garden soil is designed for in-ground planting and has a different composition than potting soil. Potting soil is specifically formulated for container gardening and typically contains more organic matter, perlite or vermiculite for drainage, and a balanced nutrient mix.
Can potting soil be reused?
Potting soil can be reused, but it’s important to amend it with fresh compost and fertilizer before planting new plants. Reusing soil can lead to nutrient depletion and disease buildup over time.
How often should I replace my potting soil?
It’s recommended to replace your potting soil every year for best results. Over time, the soil can become compacted and lose nutrients, making it less effective for plant growth.
Can I make my own potting soil?
Yes, you can make your own potting soil using a mix of organic matter, such as compost or coconut coir, and minerals like perlite or vermiculite for drainage. It’s important to ensure that the soil is balanced in nutrients and pH level for optimal plant growth.
