I have a problem with an invasive "flower" here in Orlando.. "Mexican Petunia".
I have a very limited area in my yard that has shade and I am slowly turning it into a rose bed for growing English Roses.. (so far I have three and they are doing well on their second year).
Half the bed area is totally loaded with these Mexican Petunia. I didn't even plant them.. they sprouted up the year we bought our house and just kept growing.. last year we made a HUGE mistake and used a weed-eater on them. They grew back three times as thick.
I am considering digging them entirely up (it's like a 12 x 8' area so it's gonna be a big job).
My question is this. I know I won't be able to completely keep them from coming back.. some have grown under our pavers by our back door.. and well they just come up everywhere!
I have read about the roundup spray (I never have used this stuff).. apparently you can carefully spray it on a weed or plant and it will kill it down to the root.. which sounds feasible BUT I wonder about it getting into the soil? I want to plant 4 more roses in this area and want to keep the soil safe. I also worry about the spray traveling over to my already established roses..
