Cheap
plant tags
Buy venetian blinds at a thrift store or yard sale
for next to nothing and snip strips for tags as needed.
The plastic fused to the thin metal used to make the
slats is already treated to resist sun rot. One side usually has a matte finish
that is great for writing on. #2 pencil lasts much longer than ink, which will
sun-fade.
Most of the plastic ID tags sold by professional
greenhouses tend to get brittle in about 3 to 5 years. Tags made from blinds
will last 7-10 years. Pencil marks are also easy to remove with a scouring pad
if you want to reuse labels.
Also, use 2 tags and sink one writing side out into
the pot under the media so if a tag fades or is removed you still know what it
is.
This double tag system is ideal for club plant sales.
The customer gets one tag and the cashier gets the other.
