I've been keeping a journal for over 20 years now. I write down the botanical name when I buy it and from where. I also have divided my garden into areas and mark that down where I have placed my new plant. A spread sheet has helped me keep track of plants by area and date they begin to bloom. When I forget a name it is easy to look up the area and find the name since having "too many plants" can get all mixed up in my mind. Did I just write TOO MANY PLANTS. You gardeners know what I mean. Looking back over my journal or data base in the winter months enlightens me to the fact that I could have taken that trip around the world with all the money I've spent on plants that no longer are with me. Gardening keeps me motivated and the birds, wildlife and insects always peek my interest to learn more. I love nature! I can't act old or lazy there is just too much to do.
