A Miracle grow called Organic Potting Soil The best soilless potting Mix

Potting mix or potting soil refers to the media people use to grow vegetables, plants etc in containers. It is generally used as an substitute to soil for growing plants.

What are the components: 

The life of the potted plant depends on a large extent to the quality of its potting soil. So choosing right kind of potting mix is essential. There are various ingredients which are generally used as potting soil. To prepare the best potting soil you need to know the ingredients well. Here are some of the popular ones:

Coconut coir: It is generally marketed in the form of compressed bales. Prior to using it you need to add some water.It is made of coconut husk. More on this in this article.

Peat moss: It used to be the most common type of potting soil but due to problems like environmental issues now-a-days its use got reduced a bit. There can be different types of peat moss, the most common is sphagnum peat. Peat moss is not very good for re wetting. More on peat moss is here.

Soil: Now a days most people avoid this media to prepare any potting mix. Though it has more inbuilt organic nutrients than most of other media, the problem is endless. Using soil can increase the total weight of the mix, and make it prone to water logging. Also normal soil contains weed seeds and pathogens which need to be removed first.

Vermiculite: It is a very efficient product for using in smaller containers. It is prepared by treating mica. Vermiculite is very light in weight and has a very good water absorption capability. More on vermiculite is here in this article.

Perlite: it is basically volcanic ash. Finer the grain larger its capacity to hold the water. It is neutral to slightly alkaline in nature and is a good way to reduce acidity of the potting mix. Perlite is dangerous to handle as its dust is highly irritating to lungs. Use proper precaution before handling . Interested in Perlite? Find out more in this article.

Sand: It is generally used to increase the porosity of the mix. It also increases the weight of the mix. It is a great ingredient in case you are planning to grow cactus and other succulents.

Wood chips: Sometimes wood chips, pine bark etc are also used as ingredient to potting mix.

Characteristics of a good potting soil:

1. good porosity: the best potting soil general has AFP or air filled porosity range between 10 to 20.
   

   
2. Fast absorption of water: It should absorb water pretty fast.
3. light weight: Potting mix is used for planting in containers. So it should be light weight so that the shifting of pots can be done very easily. For this purpose in most cases people use soilless potting mix.
4. You should select the ingredients which are readily available to you and are not very expensive.
5. Potting mix needs to be weed and Pest free. In most of the cases it is sterilized. It should also not contain any toxic substances or extra nutrients or salts.
6. The ingredients should be such that you can easily store them. For example you can store coconut coir in bales form easily for a few years.

There are various types of potting mix available in the market. Some of these are:

Potting mix for every plant: This type of organic potting soil can go with most of the plants and vegetables. The pH of the mixture is slightly acidic to neutral. Mix coconut coir with perlite or vermiculite in the ratio of 3:1 for this.

Acidic potting mix: These type of mix is generally for the plants which love acidic medium. Ideal mixture would be to add organic matter such as peat moss and perlite or vermiculite in 4:1 ratio.

Cactus friendly mix: Cactus and other succulents require very good drainage. Due to this reason the potting mix needs to be with extra drainage facility. Add a little bit of sand along with coconut coir and perlite to make a proper mix.

Seed starters mix: For seed starters add coconut coir and perlite or vermiculite in 2:1 ratio. Many people prefer peat moss in place of coir. In case of peat moss the ratio would be much lower.

Different soilless media for growing plants

For a good growing media it is necessary that the plant gets a healthy balance of water and air.Soil sometimes contains harmful bacteria and fungi, and prone to be infected by pests, weeds and soil-borne diseases. The soil-less media are generally considered cleaner and sterile. These media, as the name suggests, doesn’t include soil; plants are grown in different organic or inorganic materials. Soil-less media are getting more and more popular particularly among container gardeners these days.

Some of the most commonly used alternative media are:

1.       Peat moss: It promotes good aeration and water retention capacity. It is light weight and sterile and ideal for germination of seeds. Usually used with other other media.

2.      Perlite: These are basically expanded volcanic rocks and white in colour. It is very lightweight and holds air. Unlike peat moss it doesn’t hold water so need to be mixed with other media for best use.

3.       Vermiculite: It can be used as a substitute of perlite. Like perlite it also doesn’t hold water. It can retain nutrients and help a mix resist changes in pH(a measure of the alkalinity or acidity of a medium).

4.       Coarse sand: It is another medium used by people. Though it improves drainage and aeration, doesn’t retain water.

5.      Coconut coir:Now a days this medium is getting more and more popular. It is the extracts from the coconut husk. It has the same properties as peat moss but with much less mess.

 Your own mix:

Depending upon your choice of crops you can prepare your own mix. Standard practice is mixing Coconut coir(or peat moss), perlite(or vermiculite), small amount of fertilizer(Soil-less mix doesn’t have much fertility by itself. So you need to provide fertilizer from outside) and ground limestone(so that soil-less mix will contain the nutrients also).  There are several other soil-less mix recipes available online which you can easily find. Also there are several ready mix available for you to buy.

For best results:

1. Lightly moisten the mix before filling the container.
2. Don’t pack the mix too tightly when planting.
3. Water thoroughly after planting.
4. In absence of fertilizer in the mix, start fertilizing two or three week after plantation.
