Wow, looks like they revamped the home page once again....Used to be a "garden discussions" you could click on left hand column, but looks like they have now listed all the topics on the left and broken the gardening ones down by single topic (ie hellebores, garden).

FOUND it...under "Featured topics" (left column), you'll find "EXPLORE TOPICS"

Click that...will bring you to "Garden Topics" all listed alphabetically.

Found it!

What a mess Houzz has made of what used to be a Great Garden site.

I agree I miss the old GardenWeb.... houzz has it's place but I miss the GardenWeb

I had bookmarked the page with alphabetic list of topics so can still get on like we did in the good old days. Hope I can copy the link and put it here so life can get back to normal.

Please let me know if this works for you, ok?

oops sorry for being redundant!
