I’ve tried everything from the $1.50 per large bag stuff at Big Lots and the Ace Hardware stuff to all the different MG products. I seem to gravitate back every year to Fertilome Ultimate. It is a little more expensive, but it is a smoother blend with less woody material and no fertilizer. I want my mix as sterile as possible to prevent damping off of the new seedlings, and I don’t want fertilizer included in the mix. I’ve found the MG fertilizer in very dilute amounts, applied after the first true leaves have appeared; causes my seedlings to green up real fast and grow at the rate I prefer. I plant my seed in late December each year and I want the plants to be about eighteen inches tall with heavy foliage and sturdy stems. I attempt to grow them in a manner which seems to work best for my area and my conditions. Folks in other areas and with other conditions may find different methods work best.

In my experience, the sooner I can promote a deep, luxurious; green color in my seedlings; the better they grow. I know the color indicates a good mineral balance and a high chlorophyll content in the plant. I’ve never understood if the high chlorophyll promotes photosynthesis or if it is only a by product of photosynthesis.

Nope! I had a grin on my face the first time I read it. I just didn’t comment on it.

Ok, glad you mentioned it. I cracked up and had to read it twice. Too funny!

Unintentional Experiment: Vigora vs Miracle-Gro Potting Mix General Discussion

Is Vigoro Triple Mix safe for growing tomatoes?

I planted some kale and hot peppers in containers in my garden. A couple of days after filling out the containers I realized the soil I bought wasn’t an organic soil, just a Triple Mix type, Vigoro brand.

I’m wondering how safe it is to keep them, is non-organic soil suitable for growing plants I intend to eat (do they contain pesticides or other chemicals) ? I’m looking for MSDS or some kind of hazardous product DB to check what exactly is in them or at least some objective information that there isn’t adverse health effects from eating anything grown in it.

I don’t know if it makes a difference but the roots were only in contact with the soil for a couple of days until I switched them to an organic soil.

Since anyone can set up their own triple mix business without regulation and there are no controls over what can actually be in it there is no such thing as a strict database of scientific information for this product; MSDS depends on the fact that the products listed are very narrowly defined and consistent.

There have been some efforts to define what triple mix is (see for example this website where the author claims a background in chemistry) but that of course only takes us so far. Once you identify primary ingredients such as topsoil, compost and other materials you then start asking well where did the compost come from? While it might sound organic we bear in mind that some of it might have come from street side pickup from Joe Blow’s yard where he insists on zero weeds and indulges in a chemo blitz to ensure that fact. Municipalities are trying hard to recycle stuff, and while they can effectively provide a big machine to chew up and turn the inputs they rely heavily on soil organisms to provide a good end product but in effect just throw it out the door once the hot fermentation is over.

A good source of information is reviews of widely sold products. When you see observations such as a “bag of dirty wet twigs” you are forewarned, and can take comfort when you see warmer reviews flattering the producer.

In my area there is a seasonal business which starts up each spring specializing in bulk soil, manure, peats, compost, stone and so on for landscapers and gardeners. It will probably be easier and more reliable to talk to them than to corporations. They may know the farmer who supplied the manure and a word from him might ease your mind about the quality.

The final word might be that root hairs do the final selection of what goes into a plant. Living things are pretty selective about what they allow to pass that barrier. See this treatment for a detailed discussion of how root hairs work. If you do not have your own garden and only require small quantities, find a gardener who will be willing to supply you directly with soil and insists on taking it back once you are finished with it.
