How do I kill weeds in my yard that roundup just wont take out?

Answer 1

The first thing to do, is identify the problem plants. Annuals return from seeds. RoundUp doesn't sterilize seeds or the ground. That is why you can plant soon after using it. Woody vines and brush have too much root system to be taken out by that herbicide, in one application or even three. Some newer weeds introduced in some areas are resistant.

If there are particular weeds that plague you, take samples to a good feed and seed or garden center for identification. If you know how to find the Extension agent in your area, take a sample or photo there. Once you have it (or them) identified, you can wage war intelligently. .

Answer 2

For some reason, weed killers that are supposed to be for grass and weeds (like RoundUp) aren't effective at killing woody weeds (weeds that have almost a wood-like stem). Yet, weed killers that are designed for use on lawns (kill the weeds, but not the lawn) are effective for woody weeds.

Either mix the two types of weed killers together or spray them in separate applications. That should take care of just about every weed in your yard.

Answer 3

This works extremely well for me. Mix Roundup with Weed B Gone this combo even kills Roundup ready cotton (a genetically engineered strain of cotton that is not adversely affected by the application of roundup)

Answer 4

Depending on the type of weeds and surrounding vegitation... Roundup is designed for broadleaf weeds... but will not kill things such as poison ivy or woody plants... for the hard to kill plants such as these try Ortho Poison Ivy Killer...
Becarefull of surrounding plants when using these or any other types of herbicides because they are systemic which means they go thru the entire plant including the root system...
For a cheap easy fix for some weeds you can also try ammonia . Good luck

Answer 5

Use straight bleach in a spray bottle. It will dry the plants out and will wash away with the rain water.

Answer 6

I pull them out myself. Afraid to use anything stronger as it might kill the good stuff.

Answer 7

for a real easy organic method, just cut off the plant as low as possible and pour boiling water over the roots.... if the plant is small enough, no need to cut it off before placing boiling water on the roots.

Answer 8

Hand pick or use a scuffle hoe

Answer 9

Blow torch
