Unless you are blessed with a far better memory than I have, you take notes, maybe on little scraps of paper that you lose half the time, plus where did I leave my pencil, or if you have a notebook... where did I set it down, or the pages get wet and previous entries are illegible. I bet you also gets lots of junk mail every day, advertising letters, solicitations for donations, etc. that you toss without even opening. Now, here's my solution to note taking. Save at least one of those unopened envelopes every day, preferably one that is fairly stiff and has plenty of white space on the back. Insert your pen or pencil under the flap at a top corner for a couple of inches. This will hold your pen in place so you won't lose it. When you notice something you want to make a note of, write it down: "peony 'Bartzella' opened its first flower today" or "I absolutely must weed this driveway daylily bed today" or ..... Then, when you go into the house, write down the info you want to save in your journal, plant record book, etc., and after you have completed the must-do weeding, or watering, or transplanting, finally toss the piece of junk mail in the trash!
