Noxious Weed Identification

Here are several indicators that you might be dealing with noxious weeds…

There’s something growing out in the pasture or along the creek and it seems to be overtaking all the other vegetation.
The cows & horses won’t touch it, even if you pour molasses all over it.
It’s a real nuisance; the seeds stick to everything including the dog, the horses, the cows, the deer and your finest chore jacket!
The blossoms are purple, yellow or white and none of your animals will eat them.
Your neighbors are spraying for noxious weeds on their adjacent properties each year.
Your pasture looks worse every year even though you’ve been grazing it less and less.

Do you have noxious weeds on your property or not? That is a common (and wise) question. Over time, noxious weed infestations reduce the productivity of your land, increase wildfire potential, reduce stability of banks along streams and rivers and can even impact insects and birds which are important pollinators for our wild and cultivated plants.
