When you make your own potting mix for growing tomatoes, you save money. There are dozens of recipes to use to make your own potting mix. Here is an easy one: 1 – 1 – 1.
1 part inorganic material for bulk (peat moss or coir)
1 part inorganic material for good drainage (perlite, vermiculite, or coarse sand - or a combination of these)
1 part organic material for water retention and nutrients (compost, humus, garden loam, or commercial potting mix)
Experiment with these specific ingredients to find a good combination that works for you.
To make the mix …
ingredients, a large tub (or wheelbarrow) for mixing, trowel or shovel, and gloves.
In a large bucket or tub, pre-soak sphagnum peat moss or peat coir in warm water, in a two-to-one ratio (2 parts product to 1 part water), until water is absorbed.
Add other inorganic ingredients to the peat mixture. Combine together.
Add organic ingredients and mix.
If using the potting mix right away, then add the appropriate amount of time-release fertilizer for pot size (as indicated in fertilizer instructions.) If saving the potting mix to use later, then store it.
