Stickers....Any form of pokey stuff that sticks to your knees, elbows and arse..and hands too!..It migrates from these listed places into you couch, carpet, truck floor mats, wifes car floormats, then from these places it get picked up by other people to go and move into their yards!
to the best of my knowledge, the stickers I'm referring to this year is perhaps "Pigweed" or a variation of it.(That what the Smiths man told me last year)...Most all my bremuda grass has been taken over by pgweed last summer..My Zoysia has bee holding its own so far.
We also have "Beggars Lice"..At first you might think that beggars lice are ""sticky"...They are more like "Velcro Balls"
We also have :"Goatheads", grass burrs, and a few more that i cant remember right now,,,....Then theres the trusty "Mesquite Thorn"..You can trust it to tear your scalp open when in the middle of mowing your land!
The "Pigweed" is what keeps me off the groung last season. I used a pre emergence this year and so far I see no new plants.
In California, there was something we called "Stinging Nettle" It was viny and grew in the small ravines we would run around in..You would be all scratched after entering into a world of this stuff
well,...these are stickers..... :)
