I find most gardeners and plant lovers to be very sharing, very giving. They have snippers in hand ready to cut off a tip to share; they harvest seeds or dig up plant babies to pass around. Identifying little cuttings as they grow into big plants is difficult sometimes because the ID tags wear off, the ink washes off or gets rubbed off, or the tags simply get lost. While this idea won't keep you from losing your plant ID tags, this will help you keep the identity of your tiny precious growing plant for a long time.
All you need are some empty, washed aluminum cans, a pair of scissors and a ball point pen.
1) I used small kiddie scissors because they were all I had at the time, but I think long adult-size scissors would work. Use the point and pierce a hole in the sides of the can to separate the bottom and the top. Today's soda and beer cans are not your grandma's cans. Aluminum cans are thin these days. They are easy to pierce, easy to cut. I did not wear gloves at all but if you feel more comfortable wearing them, go for it. The cut-can edges can be sharp and there will be shards of flying aluminum during this project, so protect your area.
2) Carefully cut around the bottom and remove the top and bottom of the can. Because it is round, the cut will not be straight and perfect. Some of the metal will curl. Be careful! Discard the top and bottom or if you find some other use for them, let me know!
3) I found this step the easiest; tricky but easy. Cut half way up the can as if to cut in half. Turn the can around and cut half way up the other side. Finish your cuts on both sides. You will end up with two nearly equal pieces. They will not be perfect, but they don't need to be perfect.
5) Now with two nearly even pieces, begin to cut into thirds for your plant tags.
6) Holding two pieces, cut points on the end for easy insertion into the soil.
Happy Gardening! Happy Sharing!
