I Tried Mixing My Own Soil Instead of Buying Bags, and I Wouldn’t Do It Again
I spent most of a Saturday afternoon hauling wheelbarrow loads of yard soil and half finished compost across the lawn to fill part of the third bed, and by the time I finished I was sweaty, my back hurt, and I genuinely couldn’t tell you if I’d saved any money doing it that way instead of just buying bags like I usually do. That uncertainty is what pushed me to actually think it through instead of just repeating whichever method felt more virtuous at the time.
Why I decided to try mixing my own
I’d filled all four beds with a mix of bagged and bulk delivered soil over the years, and at some point I got it into my head that mixing my own from yard soil and compost would be cheaper and, in some vague way, more satisfying, more in keeping with the whole idea of the beds in the first place. I decided to test that assumption properly on one bed instead of just assuming I was right. It seemed like a reasonable thing to try once, especially with the compost bin sitting right there looking underused.
What the mixing actually involved
Digging yard soil meant choosing a spot away from the beds, breaking up the ground with my spade, and sifting out roots and rocks by hand as I went. Combining that with compost from the bin meant scooping out material that wasn’t fully finished breaking down and picking through it for the avocado pits and corn cobs that never seem to go away. All of that took real time, spread across parts of two weekends, before I even got to the point of actually filling the bed. I hadn’t accounted for how much of the work would be sorting and sifting rather than the more straightforward business of moving soil from one place to another.
What I expected to save
I went into this expecting to save a meaningful amount compared to buying bags, since the yard soil and compost were technically free, already there, no trip to make and nothing to carry home. I also expected the process to feel less wasteful, since I was using material from our own yard instead of buying something trucked in from somewhere else. On paper, before I’d actually done any of it, the whole plan looked like an obvious win, the kind of decision that seemed too sensible to question.
What actually happened
The honest answer is that the time cost ate up whatever I saved. Digging, sifting, and hauling took hours I don’t usually spend on a single bed when I just buy soil and pour it in. My back was sore for two days afterward in a way it isn’t after an afternoon of unloading bags. And the quality of the mix wasn’t obviously better either, it had more inconsistency in it, clumps of clay from one part of the yard, a few stray weed roots I missed while sifting, than the bagged soil I’ve used elsewhere.
Where I misjudged the whole plan
I think I underestimated how much of the cost of buying soil is really the cost of my own time and effort, not the money for the bags themselves. When I roughly weighed how long the mixing took against how long it takes me to load a wheelbarrow with bagged soil from the car, the comparison didn’t favor mixing my own the way I’d assumed it would going in. I wanted the more self reliant option to win, and it just didn’t, at least not clearly enough to be worth repeating.
Running the actual comparison
To be fair to myself, I did try to make this a genuine comparison rather than just a vague impression afterward. I roughly tracked how long the mixing took across both weekends, and I compared it to a previous bed I’d filled entirely with bagged soil bought in one trip. The bagged version took under two hours from loading the car to finishing the bed. The mixed version, once I added up the digging, sifting, and hauling across two separate weekends, came out closer to six or seven hours total, even though I never sat down and timed it with any precision.
The part I didn’t expect to matter
What surprised me most wasn’t the physical effort, which I’d half expected, but how much mental energy the whole thing took. Buying bags is a decision I make once, load, and forget about. Mixing my own meant constantly deciding how much yard soil versus compost to use, whether a given scoop had too many roots in it, whether I’d sifted enough. That kind of ongoing, small scale decision making turned out to be more tiring than I gave it credit for beforehand.
What I’d actually do next time
I’m not going to pretend mixing my own soil was a disaster, the bed is filled and the plants in it are doing fine. But I can’t honestly recommend it as some kind of smarter or more economical choice over just buying bagged soil, at least not for someone in my situation with an ordinary sized yard and no particular surplus of good compost sitting around. Next time I need to fill or top up a bed in any serious way, I’m going back to buying it, and I’m not going to feel like I’m cutting corners by doing that.
