UCANR – UC in our town means University of California and ANR means agriculture and natural resources – the UCANR is the “Extension” part of our university system. You'll find such wonderful websites as https://www2.ipm.ucanr.edu/What-is-IPM/ - which introduces you to the idea behind “Integrated Pest Management” - which helps you – foremost, in identifying your insects and links will take you to pages that tell you a.) if it is beneficial or not; what insect species feed on that insect or need that insect to survive and b.) proper ways to control without using harmful pesticides.
One of the UC sites I visit frequently is http://homeorchard.ucanr.edu/ . It basically follow the out line of the ANR Orchard book – except the book is called The Home Orchard. Why they couldn't have the same name, I don't know, but I use both a lot – if you want to have fruit trees, use this site and book to get smart before – not after – you buy!
If you need more info on your Sunset Zone, http://cagardenweb.ucanr.edu/Your_Climate_Zone/ will put you in tune with where you are and what you need to do. I was amazed to see this is a UCANR website now!
And to see what publications you can get from ANR, go to https://anrcatalog.ucanr.edu/ and be amazed that they have articles on gardening and so much more! I consider “Pests of the Garden and Small Farm” as one of my most revisited book!
For seeds, for tools for cover crops and all, https://www.groworganic.com/ is a California concern out of Grass Valley, CA. They have six catalogs a year and I like getting these catalogs because they just don't try to sell you stuff, they spend a good deal of ink, explaining how to use the tools, or which cover crop seed you need to fulfill your needs. I have used these catalogs in classes as required reading material. They also sell the Broadfork that I brag about.
Gardener's Supply Company, https://www.gardeners.com/ is a commercial site, but they often have things I've found no where else. I've ordered tomato towers from them and the quality is very good.
