Things to Consider Before Buying

What’s the best indoor potting soil?

Although indoor plants are more sturdy and there’s not too much fuss when it comes to their nurturing, an experienced gardener can’t underestimate and ignore their needs.

One of the first things you need to take into consideration is the type of potting soil you’re using. Some plants thrive better in a more acidic environment and others in a more balanced one.

When it comes to drainage make sure the potting soil is able to absorb the excess moisture fast, but not to get too dry and provide good aeration for the roots to grow healthy.

Lastly, some plants may require more nitrogen to help them grow and this versatility is why you need to dig deeper and find out what suits your plants best.

What’s the difference between indoor & outdoor soil?

There aren’t any significant differences in indoor and outdoor soils except for the product label. It’s good to know that they both contain the necessary nutrients essential for optimal growth.

Nevertheless, it’s important to remember that you can use outdoor potting soil for your indoor plants, but not the other way around.

What’s potting soil made of?

Most of the soil mixes used for indoor plants are peat-based and have an adjusted pH from the added lime.

Moreover, some of the soils we presented in the article are enhanced with fertilizer or water-retention agents.

A quality indoor potting soil mix usually consists of peat moss, perlite and vermiculite. These mixes are able to absorb moisture pretty well, however, can dry out quickly.

This is why you can enhance them with fertilizers or purchase a potting soil instead of a potting mix since they already contain additional nutrients.

If you’re an experienced gardener, you must’ve notice that a change of soil goes a long way when it comes to plant health.

Thus have in mind that peat-based soils aren’t designed for long-term use and its essential to change it up within a year or two depending on the plant condition.

Below, we review some of the basic ingredients used in potting soils:

Sphagnum

This is a natural plant material which provides aeration, has water-holding capacities, it’s light-weight, infertile and acidic. This ingredient decays slowly and becomes compact over time.

It can provide some beneficial ingredients and when used it’s usually adjusted for fertility.

Furthermore, sphagnum can either be dried sphagnum moss that is harvested live and then dried and peat moss which is basically decayed sphagnum from organic peat bogs.

Coconut coir

Coconut coir recently became famous in gardening. It’s made of coconut husk fibers and good water-holding properties than peat moss.

With a neutral pH, this ingredient is more acidic than peat moss and its best used when combined with it since they’ll complement each other.

Perlite

This is a well-known volcanic glass that is non-toxic and reusable and it has a neutral ph. Perlite is really good at providing aeration to the soil and it makes it fluffy. It has micro-pores which absorb water and fertilizer for the roots.

Pumice

Pumice is also a volcanic leftover and a great soil conditioner quite similar to perlite. One of the differences is that it’s heavier so it doesn’t float and it provides good drainage and aeration.

Vermiculite

This ingredient absorbs more water than the previous two so you can use it for the plants that require more water or for the ones you forget. It has a neutral pH, doesn’t decompose and improves aeration.

Sand

Sand is a rather common ingredient in soil mixes because it is inexpensive and reusable. Have in mind that it doesn’t absorb water.

What types of soils are there?

All-purpose potting mix

One of the classic options is the all-purpose mix which is light and spongy it can hold moisture really easy, plus it’s fertile and it has a good pH level.

Succulent mix

As the name implies this mix is specially made for succulents and cacti plants. It doesn’t hold moisture and it drains out fast. Moreover, it can contain sand, it has average fertility and it’s slightly alkaline.

Epiphyte mix

Weak-rooted plants such as orchids need more aeration and structure thus, the ideal soil for them is infertile and acidic. Usually, the bark is one of the main components.

Specialized mixes

Some plants such as bromeliads, azaleas, African violets and evergreens require a special mix that can be quite convenient for use.

How to improve your potting soil?

If you want to be on top of your gardening activities, there are a few steps you have to take for soil upkeep:

  • Repot yearly. One of the most practical and logical options is to repot yearly in order to provide your plants will the necessary nutrients from the new potting mix.
  • Flush the soil. Every 4-6 weeks make sure you flash out the soil in order to remove any accumulated fertilizer salts or tap water deposits.
  • Wick your pots. Use a wick and insert it in the pot through the drainage hole. This will help wick away excess water and improve drainage and you’ll avoid root rot.
