Be sure to turn over the composting material at least 5 times during these 2 weeks in order to ensure that the material is composting throughout. You can also add worms to your compost, which helps the composting process.
Perlite is a good sand substitute. Made from volcanic rock, perlite is pH neutral and can improve how water drains from the soil. It is not as heavy as sand. [3] X Research source
Peat moss does have high acidity, however, and may need to be counterbalanced to improve the pH balance in your soil. You can also use ground-up newspaper in place of peat moss, which will also help retain water. [5] X Research source Coir fiber is another option to take the place of peat moss. Coir is the fiber from coconut husks and will improve water retention. It is usually sold at garden centers as a compressed brick that expands when moistened. [6] X Research source Bark can also be used as a partial substitute for peat moss. It creates a lot of air space in the soil, although it does not retain water quite like peat. [7] X Research source Some experts suggest avoiding bark, however, because it can immobilize nitrogen, a crucial component of good potting mix.
Choose either a medium grade or coarse grade of vermiculite.
Limestone is another typical nutritional ingredient. Limestone is used to increase calcium or magnesium levels in the potting mix. [9] X Research source Dolomitic limestone is best to get a combination of both calcium and magnesium in your soil. The exception to fertilizing would be if you want to use your potting mix to start seeds. Skip fertilizers for sensitive seedlings.
Large receptacle for mixing: This can be a large bucket, garbage can, wheelbarrow or other container. Container for measuring: Some of the materials will be added in smaller amounts to the potting mix. It is helpful to have a container to measure accurately. A 5-gallon bucket is a useful size, as are 1-cup measuring cups. Water: Have a watering can and hose available. Trowel: A trowel will be useful for mixing your materials together. Shovel: Have a shovel ready for shoveling larger amounts of soil, peat and compost into your mix. Hardware cloth: Hardware cloth is a wire mesh screen that will be used to push your materials through to sift out the large pieces and debris. One-quarter inch hardware cloth is ideal.
Use a mixing barrel or large garbage can for mixing your potting mix.

For everyone 5 gallons of other ingredients, add 1 cup greensand; 1 cup blood meal; ½ cup bonemeal; ½ cup lime; and ½ cup rock phosphate.
An ideal pH level for most plants will be between 5. 5 and 7. 0[11] X Trustworthy Source University of Vermont Department of Plant and Soil Science Plant and Soil Department at University of Vermont’s College of Agriculture and Life Sciences Go to source To raise the pH levels, or to make it more alkaline, add some lime. To lower the pH, or to make it more acidic, add more sulphur. Make small batches of soil to test different mixtures and proportions. This will help you get a feel for how different ingredients produce different pH levels.
If the majority of seeds do not germinate or the seedlings grow slowly, your potting mix might be poor. Try a different recipe for your potting mix. Search online for “potting mix recipe” to find another option. Remember to skip the fertilizer in your mix if you’re going to be using it to start seeds.
