Changing out your feather flags regularly increases their effectiveness. Order the 'flag only' to keep your cost down and reuse the ground stake and pole.
For example, you could buy a 12' Annuals flag with the ground stake hardware for $136 and then buy only the flags for other topics like perennials, bulk mulch, fresh fruit and firewood for $81.60 each.
