I use rough garden maps - they also help me to plan. But they are only as good as I make them, I have to keep them current.
I also use the "Impress-o-tags" Just started with them last year, so the verdict is out.
When I receive a shipment of daylilies, I plant the tag that came with them in the ground - just in case. Every now and then I come across something that just doesn't make sense - hopefully this will help.
For dips, I put an asterisk in front of the name: *Catherine Neal
This year I have taken those garden maps,shrunk them down a bit - and squished them all one one side of a sheet. I am going to use the garden maps to help me with bloom information. 1 for each day. I can highlight the bloomers, and make notes on the back. As long as I date the sheets, I can go back to them to put the information in my database. I hope it works, instead of those scraps of paper that I can't decipher a week later.~Jan
