Lasagna Gardening will tell you how to prepare the soil - the trick is that you don't have to!  It's easy.  You pile 'stuff' up on the hard dirt that's there - and you plant in the new pile.


Square Foot Gardening will tell you about spacing the plants for the most effective growth - you can get a lot with just a little space.


Carrots Love Tomatoes will tell you what plants do well with each other, and which you should avoid planting together.  You can create a symbiotic relationship between plants so that they protect one another from bugs... this helps a lot because you don't want to spray poison on something you later hope to eat.  

Self Sufficiency in Style - www.go-self-sufficient.com/
I used to follow this site regularly, but the writer has some issues with his government.  It got pretty bizarre.  Still if you leave out the weirdness, it's is an inspiring site.


Artistic Gardens - https://www.artisticgardens.com/catalog/index.php   
This isn't so much a person's website as it is a site for a seed catalog business.  Why it's so fascinating???  They have 35 cent sample seed packets.  And since you don't usually use even 1/4 of the seeds in a commercial packet, this saves you tons of money.
