Here in Oregon I plan and plant 4 x 10 foot, raised, veggie beds every year for my dad. We are lucky here to have pretty mild extremes in any season and a relatively long harvest season. Last year we were still getting peppers into early November. Our soil has a lot of clay just a few inches down so raised beds is the way to go for us.
We plant what we intend to preserve. The harvests aren't reliably spaced to live immediately on the produce but when its time it's a glut. We plant a few staples each year and some experiments each season. For preserves we grow green beans, butter beans, beets, carrots, onions, tomatoes (Roma and heirloom), and bell peppers (usually a mix of green, and yellow Californian breeds). With the warmer and longer summers in recent years, we are trying paprika and jalapeno peppers and squash this year.
We started it as just fun but for 4 years now it's really supplemented the winter diets of two households. We can (jar) most of it as salsas, chutneys, and herbed blends, rarely pickles; but harvest fresh meals are a treat!!
We use a mix of black enriched (mixed with cooked manure) bag soil and mulched native soil with compost. We have tried different homemade fertilizer recipes (things like potting lime and mulched dried fish - I know sounds crazy...) but we haven't found anything that makes crazy growth or yields. We try to avoid too many chemicals, but we'd rather have edible food through the power of science than totally 100% organic pest-ridden garbage... ;)
I'm pretty sure my dad uses a little Miracle Gro when I'm not there, but I haven't died of rampant mutation yet! This year we've tried a trick using sugar water. It feeds the microorganisms in the soil around the roots and increases the saturation of organic materials for the plants nutrition. Supposedly it can also effect the flavor of the tomatoes and peppers??? I hope so!
Mostly we let water and the sun do the work. Some years the planrs struggle, some years the produce falls off by the bucket full.
I have no video recommendations, but I do recommend older publications on subsistence farming and kitchen gardening; older as in 17-18 hundreds. They have lots of make-it-yourself tricks that dont cost an arm and a leg and are less likely to use chemicals you cant pronounce. (Although stay away from Victirian English sources; those people were crazy with the chemicals!!) :D ;D
Often you can find great books specific to your climate and region. People liked to write before TV, internet, and Battletech, came along. :)
