Here is a page from my perennial section. Each page represents a letter in the alphabet, and I clip apart and glue my seed packets down (I use the common names, it's easier for me). That way when I save seeds, I can always be able to tell someone exactly what I am giving them. Here is a page from the rose section, I have glued all the labels from the pots in here, not necessarily in order this time.
This is the page I slip into the back of the notebook, it is a drawing of my garden, with sections numbered. I did this so I could make notes as to what needs to be moved next year, what needs to be added, I just put the bed number on the paper.
What do you think? Yes, I am such a garden freak. Next I will post a picture of this drawing, with lines to show where I will be adding flower beds next year. Hope you enjoyed seeing this, I'll let you know that I have never shown this to anyone, (maybe for fear they would consider me insane). But I do so enjoy doing it!
