nice golf course u got there... itd be shame if something were to happen to it...
If you were theoretically seedbombing your own private land that just so happened to be managed like a golf course, there are some things you would do well to keep in mind. Most plants require a minimum period of time to get established, which they're unlikely to get--golf courses tend to mow so frequently and make such common use of broad-leaf herbicides that many plants would struggle to survive there. It's a deeply hostile environment for new life.
However, if you're on the east coast and happen to have witch grass on your beaches or in your garden, or know a patch of goosegrass, those are both common weeds of golf courses that show significant herbicide resistances and are nearly impossible to eradicate. The former spreads rhizomatically, so those thick white root-like structures could be stuck in the ground, while seeds from the latter would work well for more traditional seedbombing techniques.
Do keep in mind the same qualities that make them so good at invading golf courses also make them capable of overwhelming native grasslands and meadows--look to see if they present any danger to local ecosystems before spreading them.
