Plant Markers. http://zavada.notlong.com/ 27 June 2008 Plant markers. Getting tired of always running out of plant markers, I searched the Internet and ordered a box of 1000 of the white markers and several hundred of the yellow circular ones for labelling plants for seed collection. Writing is done with a black marker pen, and it withstands weather exposure well. For tying the soft covered wire center pipe cleaners from a craft store are used. The yellow circular marker is 3 inches in diameter, and the white one is 5/8 by 6 inches. This is my first year using them, anad they appear to be ideal.
The yellow discs are nice! I have a problem with planting things out then forgetting exactly what they are....
Watch out that black marker pen ink often isn't as durable as the manufacturers claim; it often fades on exposure to sunlight and becomes illegible after a few months or even weeks. A better low-price option is to use thick plastic tags, and 'write' on them with a soldering iron; this engraves into the plastic, and is far more permanent.
