Anyone know?

I'm not sure what you're asking about. If you mean the plant comments, you can find a plant, and on the left side, it will have a place to click and comment on the plant. Most of us have our home pages customized, so what we see isn't what you see.

Like Karen mentioned, since members can edit the contents of their Home Page , we don't all have the same layout.
What is the header called for the section you are referring to?

It's heading is Recent Plant Logs & it's on the home page lowest right column. I will explore the database comments area & see if that is how to record my seed planting which is what I've seen in most of the plant logs. I love garden.org's tools & this is an area I've never taken advantage to use before now.

Thanks everyone for getting my juices flowing! I'm happy to say I figured out how to record events using the calendar icon beside each plant in my list. Soon I'll see if it shows in Plant Post on the home page. It doesn't matter if it doesn't I just wanted them for my personal records.

It's great you have it figured out, Trudy. I took a look and see comments showing up. It sounds like you have a lot of nice episcias.

Ahh, good you found it! I don't have that on my Home page.
I also use the notes section in my plant list, if you click on your plant list in your profile you can utilize all the functions.

I click on the calendar icon (the square with a + on it) to the left of each plant in my list. What I add then becomes a report. A very useful tool for record keeping.
