I know Japanese knotweed spreads worse if you just try to yank it out. What other undesirables need special treatment?
The rain is making my garden beds much easier to weed, but I don't want my gleeful removal of any plants to cause them to spring up elsewhere. |
| I just keep whacking off the shoots as they appear. |
| Till up the garden beds. Makes pulling out the weeds a breeze then. |
Great way to spread bindweed. |
Little roundup before tilling then. |

| Bishop's weed will grow from any bit of root left in the soil, but better to pull and keep at it than let it go to seed. |
| Anything that spreads by rhisomes needs chemicals |
RoundUp is not that old. More people use it now than ever. It's used on most of your packaged food products as well. Anything having corn or corn products will have RoundUp on the food. |
| Thistle. I spread it accidentally for years while trying to rip it out. A few applications of a thistle spray by a landcscaper took care ofnit |
How does thistle spread by pulling if it hasn’t yet gone to seed? I agree if it has gone to seed it is a total nightmare. |
When the roots split when pulling up more grow. It's like medusa. |

Looks like some varieties of thistle have rhizomes and some just spread through wind blown seeds.

If you keep mowing or pulling it, eventually you starve the root system. You can also try a weed torch if there’s nothing immediately around it you want to save. Finally, covering the whole area (assuming it gets direct sunlight) with a dark plastic sheet for a week will fry everything and deprive it of water.
I’m not against round up, but it doesn’t really work systemically. I eliminated an infestation of bindweed across a 30x20 garden last year with a combination of religiously pulling it up/digging it up deep and plastic sheets. Haven’t seen any this year. If you keep pulling the new shoots ever couple of days, eventually the roots do run out of gas. |
