Not sure why I never did this before (Made my own soil). Definitely saves $$ when making a lot of it. I also like to look back at my posts to remember how and what I did. I often go back in time like a diary to help me remember.
Anyway … So the plan is to make potting soil for 12 pots AND a bucket of seed starting soil.
Peat Moss
Vermiculite
Perlite
Potting Soil or Compost
The straw is just used as a little filler. I actually took some out after this picture was taken.
4 Parts Peat Moss, 1 Part vermiculite. That's it. This is the seed starting soil. Pretty much what is sold in stores. Barely put a dent in my bags. I did this ratio twice and will keep it in this bucket. Then boil it before I use it inside in February-March.
Mixing in the wheelbarrow
4 parts Peat Moss
1 Part vermiculite
3 parts potting soil ( I didn't have compost ready on hand)
some Perlite
I could of added a low granular fertilizer like 5-5-5 but didn't
Filled 13 pots. Still have a ton of peat Moss and Vermiculite. Didn't even use half the bale or bag.
