Advantages of Great Potting Soil

Finding the best potting soil can make a huge difference in the growth rate and health of your plants. It helps your plants retain both moisture and fertilizer, leading to sustained and steady growth.

Don’t let the name fool you though, potting soil doesn’t usually contain much soil. Instead, it is mostly made up of lighter materials like pine bark, peat moss, and vermiculite or perlite. These lightweight ingredients allow air to reach the roots of your plants and aid in drainage. These are essential for healthy growth.

  • Heavier Isn’t Better. Don’t judge whether a potting soil is best by its weight. You might think a heavier potting soil means you are getting more bang for your buck. But with potting soil, extra weight is never a good thing. If a potting soil is heavy, it means it has been filled with materials that are usually undesirable for general growing purposes.

You don’t want a potting soil that uses a lot of heavy filler ingredients like sand because it will cut down on the air that reaches the roots. Roots need a steady supply of air to grow in a healthy manner.

  • Watch for the Fertilizer Levels. Pay attention to the fertilizer in the potting soil you choose for your container garden so you don’t add too much fertilizer or too little additional fertilizer. If the soil contains fertilizer then you will want to wait before adding any more.

Some potting soil blends have a starter charge of fertilizer while others have a slow-release fertilizer already mixed in. If you choose a starter charge fertilizer, you’ll need to add some after the first three waterings. Slow-release fertilizer lasts longer, but you’ll still want to add some additional fertilizer after the first month.

  • Beware of Specialty Potting Soils. It can be confusing to choose a potting soil that meets your needs. There are so many different brands, sizes, and types out there. If you don’t know what you are looking for, it can be overwhelming. Sometimes it’s easier to know what you aren’t looking for to help narrow down your choices.

Think about what plants you want to grow. If they have special nutritional needs that are crucial for growing them, there will be a type of potting soil made solely for them. You’ll see several brands with products aimed at people who are growing African violets or cactus. That’s because they both are finicky plants that can be difficult to grow under normal conditions.

Unless you want to grow one of these, never buy the types of potting soil which advertise they are a special blend meant for these plants. Stick to a good multi-purpose potting soil or you’ll create conditions that won’t support the growth of the common plants you’ll likely want.
