I make no pretense. Gardening is ok. When there were kids to feed. it saved money. But spending time, money and effort to grow a few veggies for the two of us is just a waste of effort. Makes no sense to spend the hours and money digging a spot, fertilizing, money for plants, then watering and weeding just to get $3.00 worth of tomatoes. Now we do plant sun sugar cherry tomatoes and husk cherries just because we can't buy them. But even at that 4 plants of each gives the two of us more than we can eat. OTH, blueberries are easy. plant the bush, water during a drought. No spray, no weeding, no bugs, just pick every July.
One year Mrs. insisted on making 20 qts of spaghetti sauce. Cost of jars and lids, pressure cooker, fuel for stove, labor planting a garden of plum tomatoes, picking peeling milling out seeds, cooking, etc. Figure it cost about $400 to make $40.00 worth of crappy spaghetti sauce. Pasta sauce is one of the cheapest foods in the grocery store. In addition, there are literally hundreds of kinds and varieties to try. Why bother? It is like people growing their own wheat to make noodles. So cheap in the store that almost no one in the US bothers to make their own from planting wheat, grinding flour etc.
If I am going to plant something, it will be something I can get so much cheaper than in the store, that it is worth the hassle. Husk cherries for instance. Minimal care, plant once, they come up every year thereafter, no spraying, no weeding, etc. Just pick seasonally.
I have at least 50 black walnut trees. In fact in the sheep pasture, they fall off and roll down hill to the bottom of the hill. I could have 4 or 5 bushels just by picking up those. The work to husk them, dry the nuts, then crack them and pick out the meats simply isn't worth the hassle when I can buy black walnut meats for $8.00 a pound. I only use about a pound a year and it would take me 3 or 4 hours effort to get that pound of black walnut meats the old fashioned way. Simply isn't worth it.
