How can I keep this forum and other favorites on my home page so I don't have to search for them?

First copy the forum address that you want to create a link to. (From your browser tool bar)

On the upper right of the forum tool bar, not your browser tool bar, there is a little icon that looks like links in a chain. The link is in between the person icon and the little bell. Click on that link icon and there will be an "add links" option. Now you'll see the form where you can add quick links to different areas of garden.org. So add the name of the forum link you copied in the first step ex. "Iris forum". Then paste the link you copied in step 1 and save the changes.

Alternatively, you can "watch" the forum ("Watch" will be just under the search box on the right when you're looking at the list of threads) and make sure you have the list of watched forums on your homepage (if you don't, scroll to the bottom of your homepage and click "Customise").

Thank you - the simplest way is to "watch" threads that are ongoing in all of your favorite forums.

The problem with bookmarks: it's too easy to lose them, for example, if you uninstall and reinstall your browser. However, if you use the "Page" feature of your browser to add an icon for the page to your desktop, it seems to be more permanent. Of course it will be unusable following a browser uninstall, but stays there on your desktop ( unless you delete it) and starts working again once you reinstall the browser. At least that's my experience.

Here's how you do it in Firefox android, and I think other browsers are similar.
1. Go to the relevant page in your browser that you want to be able to easily go to. That's probably the first page of this forum.
2. Hit the triple dot menu in the upper right corner of the browser window. Hit "Page". The hit "Add to home screen."

That's it! I keep my desktop icons locked down so they aren't getting accidentally moved around. So, if I want to move the icon to a different position on my desktop, I press and hold on it until the option to temporarily unlock the desktop appears. I opt to unlock it, and then for about 15 seconds I can drag the icon on the desktop to a place where I want it. Then in a few seconds the desktop lock resumes, and everything remains as I have arranged it on my desktop.

With reference to #1 in my above post, the first page of this forum is at https://garden.org/forums/view... . And to unlock the desktop for repositioning the icon, press and hold on the icon, not the desktop. I had to clarify that.
