Ingredients for Homemade DIY Potting Mix Recipes
Before you scroll down to read the recipes, learn about the main ingredients and their alternatives.
1. Peat moss or Coco Peat
Peat Moss: It improves air circulation and retains water. It is acidic in nature and contains less or no nutrients, and if you’re using peat, *you can add 1/4 tablespoon lime per gallon in the mix to balance the pH.
The downside of using peat is it’s obtained by destroying the remaining Mires. There are other alternatives as well, which you can check below:
Coco peat: One better alternative of peat moss is coco peat. The main advantage of using coco peat over peat moss is that its production doesn’t harm the environment. It also has macro-nutrients, and it is neutral, unlike peat, which is acidic. To learn more, click here.
Leaf Mold: Leaf mold is an outcome of the natural rotting process of leaves. You can use leaf mold to sow seeds.
Pine Bark humus: It’s derived from the composting of the bark, which originates mostly from conifers. It provides good drainage and stable crumbly texture to the soil.
Composted Wood fiber: Wood fibers are low in nutrients and somewhat similar to coir. However, they must not come from treated wood waste.
Cat Litter: It can be an option for plants that require very few nutrients. For example, cacti. Also, with a nutrient-free combination of perlite or pumice and cat litter, you give seedlings the best ground for rooting.
Note: Use non-clumping, mineral-based cat litter.

2. Perlite or Vermiculite
Perlite: Perlite is used to improve drainage; though it doesn’t hold water as effectively as vermiculite. It also helps the plant roots during temperature fluctuation. *You can also use pumice instead of perlite.
Vermiculite: Vermiculite is light and improves drainage, but unlike perlite, it retains more water. It’s a better option for plants that need more moisture.
Sand: If you don’t have perlite or vermiculite, use coarse sand. Sand is always there as a part of the soil. It is important for a stable soil structure and drainage. Sand does not contain any nutrients.
3. Compost or Well-Rotted Manure
Compost: Use fine compost in your homemade potting soil recipes. You can also make your own compost–It’s easy!
Manure: Use aged chicken, cow or horse manure, if the compost is not available.

Tips to Help You Make Your Own Potting Mix
- While making a perfect potting mix for your container plant, try to keep its texture crumbly. If your recipe is sticky, add perlite, coarse sand or its alternatives. On the other hand, if the recipe is too gritty or sandy, mix a bit of peat moss or coir.
- The most basic DIY potting soil recipe that works for every plant is–One part peat, one part perlite, and one part compost.
- Before you prepare any of the DIY potting mix recipes given here, learn about the soil requirements of the plants you’re about to grow.
- If you’re growing vegetables, the moisture retaining capacity of container soil must be increased slightly. For succulents, the opposite is true.
- Annual flowers, vegetables like tomatoes, eggplants, peppers, and cabbage family crops are heavy feeder crops. Greens, beans, and herbs are moderate feeders, whereas, root crops are light feeders.
- Pre-treat the soil with granular fertilizer or compost before planting, according to the nutrient requirements for healthy and productive plants.
