I have a weird mix of thoughts left over from yesterday's work.
Johnson grass has invasive spreading rhizomes, that break easily when pulled, especially in hard ground, leaving parts that keep sprouting.
Japanese beetles tend to pick plants based on pheromones. and their grubs end up in the ground below that area.
Pheromone based traps are available and seem to do well for attracting them.
Moles love the grubs and eat them and loosen the soil.
So. To me, that adds up to putting pheromones on the Johnson grass, so the area will be full of grubs, that will get the moles to loosen the soil so I can remove the roots easily and kill off the dad-ratted Johnson grass.
Anyone see holes in this plan? The beetles are amok, the grass is amok, seems like there oughta be a way to get the beetles to kill the grass :) And I have lots of moles happy to help!
Pearl, I love the idea of using one pest to ensnare another!
About the only problem I have with the pheromone trap is that the traps tend to attract Japanese Beetles from seemingly miles around and they don’t always stay at the trap—they sometimes munch around before getting to the trap.
I'm with Eric on this.
Other than Japanese beetles doing what they do, and then provide crunchy treats for poultry, I would love to see you "Science!" it.
Anything that makes Johnson Grass easier to dig out of garden beds is a Good Thing in my book.
"No one has been traumatized by a chicken or tried to lick something they shouldn't or attempted to eat packing peanuts so I consider it a win. Also since starting at this job I've had air conditioning every day, nothing has burned down, and nobody has been bayonetted so I consider it a step up from the last one"
