You might find the suggestions on the following website helpful for alternatives. We have used some of these suggestions with good outcomes. Maybe not as immediate or as thoroughly destructive as Roundup but quite effective with a little more effort.

Cheers and good luck.

Homemade weedkiller options

I fully appreciate everyone's concern about the environment BUT in this case the lot is almost two acres and has a nice stand of "horse weeds" 6 to 7 feet tall. Trying digging but they have a tap root that goes WAY DOWN---been there, done that. I need the Roundup for a one time application to get the tap roots; after that, controlling the weeds with cutting and digging won't be a problem.

Perhaps I will forever be baffled by folks who allegedly want to "live with nature" but who also just want to apply a little poison to it first.

I wouldn't worry about the hierba. The dry season will take care of it for you. Goats can handle the rest. You should be planting trees on that unfortunately clearcut lot!

We're with you Rob.

Once our gardener brought an assistant who brought a gas weed eater. Not only was it loud and smelly, it didn't remove the weeds. Fortunately our gardener didn't use it again and all the weeds get pulled. After a fairly short period of time if weeding is done regularly, very few weeds are left!

NO POISON!!!

Yes, I used to be a gardener/lawn maintenance man back in another life. Always pulled the weeds by hand.

What a lot of folks forget is that one person's weed may be another critter's source of food or shelter. Iguanas like certain plants, different insects like others. Some "weeds" we use for medicine.

Plants like strangler figs (amate) can quickly damage homes if they start growing in one of your walls. When their figs mature bats eat them and deposit their seeds all over our home so I am constantly searching for them and other plants trying to take root in places where they shouldn't. If I can't get all the roots, the dry season usually takes care of the rest.

NO POISON!!!

Where to buy? Much prefer Roundup or equivlant to other herbicides as it kill vegetation from the roots not the foliage. Yes, I am aware of the danger to the environment.

Why not just dig or pull up the plants the old-fashioned way instead of poisoning the environment for generations even though it's more "convenient" for you? That's what local gardeners are for. Your question is not one I like seeing my Message Board used for, though I'm sure some "helpful soul" will give you the reply you seek.
