I just sifted Back to the Roots “Premium” potting mix for 10 hours. Let's talk about it.
Let me start this post by saying I am new to gardening, so my beef with this brand could be completely unwarranted, idk, but it feels valid to me. It has been irritating me for months, so today I decided to be petty about it.
Okay, let’s get into the tea. I started gardening about 3 months ago, and this “Back to the Roots Premium Potting Mix” was on sale at my local At Home Store for $6.99 per bag PLUS buy-one-get-one free. So, I got six 12qt bags.
Now, obviously I don't know much about soil, but I have been EXTREMELY displeased with the quality of this. It popped up as the first, second, AND third result when I searched for “soil for vegetable seedlings.”
It is marketed as “premium” potting mix that's “all purpose” and “great for herbs, veggies, fruit, and flowers.” The bag even says “grows bigger plants!” but the only thing it has grown consistently is my blood pressure.
Yeah, I'm aware of the fungus gnat issue (and yeah, it's insane), but let's just set that aside for now. I'm focused on the composition of the mix. Originally, I just put my plants right into it, which were bell peppers, celery, brussel sprouts, lettuce, jalapenos, habaneros, mini sweet peppers, poblanos, sage, basil, mint, rosemary, and thyme….and they were all on their deathbed after a few weeks. I finally figured out why they tried to die was because of the immense amount of wood in the mix that was watterlogging and causing rot, mold, and stagnation.
So, everytime I needed more soil, I would have to sit and sift through it for an hour or so to get the wood out. After the wood was removed (or most of it, at least) and I repotted my plants into the sifted soil, they thrived. I did this for the past 3 months and dear lord it was frustrating, but I didn't have the money for more mix (and don't like to be wasteful) so I just had to deal with it.
Well. Today I finished my calculus final so I have a week off of school, I had no work scheduled, and I quite literally had nothing better to do….So, I took the last bag of potting mix and sifted it. Twice for good measure. For 10 hours. Below you can see the result from one whole 12qt bag, which is about 15% soil (and even though I sifted it as fine as possible it's STILL mostly tiny wood pieces) versus 85% wood chunks. Let's talk about it.
Do we think it's fair for them to call this “premium potting mix” when it's more like a glorified mulch?
Has anyone used this brand and NOT had the majority of the mix just be wood? Did I just get an unfortunate batch? I did buy one smaller bag (6qt, I think) from Walmart, and while I didn't get petty and measure it, it was extremely woody as well. I noticed that the small Walmart bag also had tons of food chunks, while the big bags from At Home barely had any.
Why do they say it's “all purpose” when I cannot think of many plants (especially vegetables) that thrive on a 15:85 dirt:wood ratio? I know my plants struggled more because they're young, but STILL, I feel like even mature adult plants would struggle in mostly mulch with very little dirt.
