The most cost effective way to have a quantity of potting soil for your use is to create it yourself. The following is advice on how to do that.
A more proper term is dirt media because the substance being marketed as potting soil is in fact soilless. Outdoor soil isn’t acceptable for potting plants since it can compact in the bud, causing drainage problems for the plant. It may contain weed seed, disease organisms, and insects. What the soilless media provides is support for the plant by anchoring the roots and also a medium for food and water to enter the plant through the roots. There are many alternatives for potting soil which may be bought ready mixed. Pro-Mix is a professional potting mix that’s soft and light and doesn’t compact readily. Additionally, there are kinds of soil especially formulated for orchids, cacti, African violets, and seed starting. I find it more economical and just as effective to combine my own.
A fantastic basic mix is 3 parts peat moss or coir (coir is very good if you can get it mass. . .from coconut hulls) and one part perlite. Perlite is the white granular material utilized in premixed lands. For every 1 gallon of this mix, add 1 tbsp of ground limestone. The top would be dolomitic limestone since it also provides calcium. Wear a dust mask when mixing and handling the substances since it’s fairly dusty and is very unhealthy to inhale a whole lot of this material. Once the lime becomes blended in a little, you may add hot or warm water and continue mixing. There is not a dust problem if the substances are moist and it seems easier to find a fantastic mix if it’s moist. Peat moss doesn’t absorb water readily when it has not been treated with chemicals to make it. It will absorb water if the water is warm-hot and you continue mixing the mixture. This basic mix may be used for many plants except cacti, carnivorous plants, orchids, and may be used for African violets but it requires a further ingredient to make it more acceptable for them.
African violet soil
1 part peat moss, 1 part perlite, 1part vermiculite. To every 1 gallon of mixture, add 1 tbsp of lime. Cacti mix. 1part standard mix, 1 part perlite. Doesn’t require lime because there’s sufficient in the basic mixture.

These are whatever else you wish to increase the potting soil to get optimal outcomes. They can provide feeding for a few months. I usually supplement with a liquid feed monthly or so merely to provide the plants a boost because occasionally the organic amendments do not break down quickly enough to feed the plant through rapid growth.
- I mix this from the handfuls. It does not matter what size your hand is just try to maintain the identical amount for every handful. Or you may use a scoop etc..
- 1 part cottonseed or blood meal. 1 part sulpomag (a product sold by that name) 1 component greensand 1 part bone meal 1 part dried worm castings (optional) 1 part compost (optional)
- The cottonseed/blood meal offers nitrogen, the sulpomag offers potassium, sulfur, and magnesium, the greensand supplies more iron and potassium, the bone meal offers calcium and phosphorous, the dried worm castings add all of the nutrients including lots of the micro-nutrients needed for plant growth, as does the compost.
- I add 4-6 tbsp of the mixture to 1 gal of fundamental soil-less mix. A few tablespoons can be added to placing holes outside also. I especially like this mix because it’s organic and supplies all the nutrients the plant needs and won’t burn the plants. I also enjoy how this is high in potassium. Potassium helps the plant to have good disease resistance in addition to makes it more tolerant of cooler/cold temperatures. . .something I like the berries to have.
One note, cottonseed meal will cause benign mould to grow on the surface of the soil. It won’t damage the plant but is unsightly. If you would like to use cottonseed meal regardless of the mold and would love to keep it under control, sprinkle a little cinnamon on the top layer of the soil.
It might be hard for an apartment dweller to have access to a compost pile, but if you do, crop it and pasteurize it for use with plants. Heat the compost to 180 degrees F and keep it there for 1/2 an hour. This may be achieved in the home oven and checked with a meat thermometer saved for this purpose.
About worm castings, occasionally they may be bought or they could be “grown” in a bin in the kitchen. It is dependent upon how squeamish everybody in the house is if you do this. I have a bin of red worms which compost all my kitchen waste (no meat) paper towels, plant clippings, and paper. They take this raw waste and turn it into dark, rich substance that’s super food for plants.
