Huffington Post has a garden section
If you go to Huffington Post's Home Page, click on "All Sections" in the menu bar, then click on "Home." Then, under the menu bar, there will be a list of feature sections - "Gardening" is about halfway down the list. Or, just visit here.
Some of the articles are pretty pablum–Which Supermodel Has a Green Thumb?, How FLOTUS is Getting Ready for Spring, The 10 Biggest Garden Mistakes (spoiler alert: #2 is Accidentally pulling up flowers instead of weeds), 8 Backyard Ideas to Delight Your Dog, 10 Adorable Little Garden Gnomes, Arrange Spring Flowers Like a Pro, and more. I think you get the picture. There are a few that are worth a view.
There's also the "Featured Blog Posts" which are essays by authors, columnists, educators, freelance writers, researchers, and of course bloggers. These are on a greater variety of topics that don't include supermodels, dogs, or gnomes.
If you're a garden obsessed voracious reader of all things garden, it's good to have on your radar. Especially if you need to know what delights a flower-arranging supermodel's dog in a garden.
