Organic Potting Soil For Indoor Plants

When it comes to the best organic soil for indoor plants, there are a few things to take into consideration. Firstly, increasing the amount of organic matter in the soil benefits its structure, water-holding capacity, nutrient mineralization, biological activity, and rates of water and air infiltration. Organic matter also links soil particles which increases its ability to hold water.

Take heed of these points to know what potting soil should contain for your indoor plants:

– A good organic potting mix for indoor plants should contain distinctive materials which include humus, a substance that results from the decomposition of plant and animal matter.
– Mulch is a mixture of organic waste products created from things like shredded newspaper and fallen tree leaves.
– Any substance in or on the soil that was once alive is considered to be organic material. It has to break down into humus in order to produce richness in the soil.
– Remember that organic material that has been transformed by microbes into humus is in a decomposition-resistant state.

Organic Indoor Potting Soil: What it Contains?

Peat Moss – This serves as your main element and helps the soil retain moisture.
Coco Coir – This product is more sustainable and is the bi-product of coconut processing.
Perlite – Most potting mixes contain white granules called perlite. It improves drainage and aids in avoiding compaction.
Pumice – If you can’t get perlite at your local nursery, you can substitute it with pumice. Both products contain natural materials.
Vermiculite – Natural mineral vermiculite keeps the mixture airy and fluffy and helps to minimize soil compaction. It also preserves moisture, which is an additional advantage. It won’t add any extra weight to the mix because of its extreme lightness.
Compost – The three main nutrients nitrogen, phosphorous, and potassium are found in compost. Additionally, it contains minute amounts of other necessary substances like calcium, magnesium, iron, and zinc. Composting offers an organic substitute for synthetic fertilizers that are filled with dangerous chemicals.
Potting Mix – Add one part perlite or pumice to two parts pre-moistened peat moss or coco coir for best results. Half a portion of vermiculite and a full portion of compost should also be added in.
Soil Alkalinity – Since most houseplants prefer alkaline soil the addition of peat moss will make it acidic. In order to balance it out, you should add one tablespoon of garden lime per gallon of soil. If you want to make sure it has been neutralized, you can use a pH tester.

Best Organic Potting Soil for Seedlings

It can be difficult to locate the ideal potting mixture for starting seeds. That’s why it is best to develop a simple and inexpensive homemade mix of your own. Although it may seem tough, creating the best organic soil for indoor plants or seedlings is very easy! The mixture, which usually requires three ingredients, is ideal for nurturing seeds.

If larger organic fragments such as twigs and bark are present in your seedling mixture, we advise removing them before adding any moisture because they can hinder seed germination and growth. Sphagnum peat, rock phosphate, gypsum, protein meal, and perlite should also be included in your seed-starter mix. Crushed coconut coir pellets, which can also be bought individually and used in any growing tray are also a favored option.

Put one in each tray cell and submerge it in water. When water is introduced, the pellets quickly expand up and fill each cell. Alternatively, for your seed trays, you can opt for an organic readymade starting mix that can be bought online or at your local garden center or nursery.
