Reddit reviews Better Homes and Gardens Complete Guide to Gardening

There are no magazines that are worth shit anymore. That era has ended.

Good overview books are both the Dummies and Idiots guide. No offense, that's just what they're called.

The Square Foot Gardening book, either edition. The concepts have entered the zeitgeist, so whether you're doing raised beds or SFG as such, you still need to know what everyone is talking about.

Any of the Sunset books on gardening topics. These are the softbound books you find on the magazine rack at Lowes with the DIY how-to books on plumbing and hanging drywall.

Your local public library has shelves full of books on gardening. Read everything, because that's how you acquire a good overview of the discipline, and as you get better at it, you can begin to choose for yourself what works for you.

Good mainstream websites are:

https://www.rhs.org.uk/

https://garden.org/

Any of the Mother Earth News articles online.

Any of the extension office articles online. You don't have to be living in their state, or even in the U.S., to read them.

If you can source a copy of this, it is awesome.

As is this.
