But what exactly IS potting soil?
Did you know that potting soil doesn't actually contain any soil at all? Also called potting mix, potting soil is basically a soilless blend of ingredients that aids with plant growth. Potting soil is the best medium for growing plants in pots. It's great for starting seeds, potting houseplants, rooting cuttings, and potting flowers in hanging baskets.
So why make your own potting soil?
There are many advantages to making your own potting soil and these include:

- Better draining than store bought potting soil.
A Few Basic Rules…
Here are some things you should keep in mind before making your potting soil.
- When it comes to potting mix, the lighter the better! Loose and porous mixtures are easier to move when in pots, but most importantly, they carry water, air, and fertilizer easier & quicker to plant roots.
- The perfect potting mix is made up of peat moss, vermiculite or perlite sand, and shredded bark or compost, and NO soil or garden dirt.
- Check out the recipe below and change it to your plants' preferences. Add soil sulfur to lower the pH or lime to raise the pH.
- For plants that need rapid drainage, such as succulents and lavender, add more sand to the soil.
- For ferns and woodland flowers that need moist conditions, simply add more peat moss for water retention.
Different Types of Potting Soil:
Like commercial potting soil, there are many different potting soils you can all make at home. Naturally, they each serve a different purpose. Each type of soil can have a different texture, different porosity, nutritional content, and water holding capacity. For example:
Lighter, fine textured potting mix will be best used for starting seeds and rooting cuttings.
Potting mixes that contain a high amount of coarse sand or pine bark will be best for trees and shrubs.
Potting soil with sandy or gravely texture is ideal for succulents and cacti.
A general, all-purpose potting soil is great for vegetables, annuals, perennials, and tropical plants.
Today we'll be looking at an all-purpose DIY potting soil mix.

- 1 bucket (2-½ gallons) vermiculite or perlite
- half a bucket (1-¼ gallons) screened compost or composted cow manure
