So I was wondering - is there anyone here whose gardening is actually saving them money?
It's kind of a question with many answers. Overall - probably not, because I kind of go all out on things, and trying to be an all organic dickhead plays into that. I'm always trying to grow something new, trying to support that little independent garden centre/supplier that might cost a little more. I'm mostly in containers as well, not raised beds, so that soil maintenance takes more effort. I feel like I always have a need for a bag of soil... and if I don't, I'll find one.
But in spring/summer my grocery bills are definitely less. Like without a shadow of a doubt. I'd say my little backyard patch is providing 90% of our fresh veggies. But I try and be smart with it and grow high density/high yield things. For instance, I love sweet corn, but it takes up so much space to grow for relatively small yield... and I can get a box of it from the farmer's market for $5, and it's delicious. So where the corn should be I'll have 3 more pepper plants, or a couple more tomatoes and life will be grand.
Where you make a killing is on growing herbs. The prices they charge for small packets/bunches of herbs is insane. And especially if you grow things that are a little more 'exotic' or trickier to find. I'd hazard I've got at lest $100 worth of red veined Sorrel in one of my beds at present... for about a bucks worth of seeds.
If you cut it all back to the bare bones and abide by a few golden principles I think you'll end up saving in the long run: grow what you eat the most of, grow what you can't get cheaply in stores, and grow for yield.
I'd like to say I'm breaking even, but I'm probably spending more. But I'd rather it be spent pottering around my garden than, idk, getting gunted on Makers Mark every night of the week.
I can't buy anything of equivalent quality, so there is really very little cost-benefit analysis. I either grow it myself or I don't have it.
This is a huge factor too. Nothing tastes better than what you grow. Potatoes are another big one for me in this category. It's a fucking travesty having to go back to store-bought spuds.
ETA: There's a guy on Youtube, MIGardener, that speaks a lot about frugatlity and making the numbers add up in your garden. He's a total dork and definitely loves Jesus, but his advice and growing guides are top notch.
