Organic Potting Soil problem

patsyann(7b)April 26, 2013

I purchased the PREMIUM brand organic potting soil from Costco and am finding my transplants (tomatoes of different varieties) are stunted and leaves are more yellowish and smaller than usual. Has anyone else used this potting mixture?
Any suggestions?

patsyann, I do not know how big these transplants are; but my opinion is that tomatoes prefer two conditions - a free draining medium and regular mounding up to grow well.
From what I have seen, the 'newer' generation of potting soils are too moisture-retentive for tomatoes.
Long ago and far away, we used "burnt earth" - imagine brown lava rock crushed to the size of pea-rock - was used to improve the drainage of tomato beds.
The material was produced by burning clay and wood slowly to make a road building material. It was also fairly acid - as evidenced by the many rusted-out vehicles.
