Guys/Gals, why bother with roundup at all? I apply a thick layer of mulch around my banana plants and pull out the very few weeds that appear by hand. You don't even need to buy that much mulch since you can use the banana plants themselves! Once your plant produces bananas, you will have cut it down anyways, so why not use it as mulch?(assuming it wasn't infected with anything) I have run out of people to give my sword suckers to, so I chop those up and toss them on the pile too. Once your "mulch" is about 4 inches thick, you should see very few weeds.
As for other plants and trees, well mulch does not work for all. While you can use it for pretty much any plant, it will need to be at least 8 inches away from the trunk in most cases. In those cases, I pull weeds by hand every few weeks... or I get lazy, let the weeds grow.. and then get inspired one day and go pull them all out at once.
I haven't experienced any ill effects yet.
Now, a few questions if y'all don't mind..
I've tried several pesticides and am not 100% sold on any of the ones I've tried.(Organocide, Bonide orchard spray, malathion oil, parifine, and a few others) --What pesticides would you guys recommend for fruit trees with fruit on it?...how about while the tree does not have fruit on it?...is there a difference?.. is there an all in 1 product I can rely on, or would I have to use a combination of two or more products?
Im sorry if Im taking the thread off topic..
