How to deal with sticky weed Galium Aparine

Asked June 5, 2016, 3:25 PM EDT

Local garden center identified weed as Galium Aparine. Not had before but is taking over my landscape gardens. Found cannot pull as breaks off easily.
Questions:
will roots resprout new plants?
will the green seeds on plants raked be viable and seed next year or should be removed?
can a preemergent be used to control future infestations?
Have not had this before and it is terrible!

Hello. Yes the roots of this plant can resprout if it is not entirely removed. From the research I saw the seeds are viable for 3 years in the soil so if there are seeds in your soil you could have at least 3 years of trying to control this weed. There is very little information on preemergents and this weed. I recommend you read labels and pay close attention to the instructions and since this plant germinates early application time could be tricky. The best means of control is to hand pull or hoe before the weed flowers and sets seed. The plants are also easier to pull when they are small. Using a mulch on the area that is infested can provide some control of seed germination. If you decide to use chemical control glyphosate is effective but read the label, it is the law. Hope this helps as you try and control the weed!

Thanks for the info. Still,have questions. Weeds are in perenial gardens like ivy and Lilly gardens. So cannot hoe. For now can only pull. However stems break off easily so hard to get at root stem to pull.
Not sure if understand answer about seeds. Now seeds are green and assume immature. Will they ripen and sprout? This is a horrible weed not had problem with before.

It would probably be best to just keep pulling! If you are pulling then you are getting the seeds too. However, you will have a 'seed bank' already present in your soil and that is why you will need to keep a close eye on that area for the next couple years. Try to get the seedlings when they are small, before flowering and setting seed. As mentioned earlier, mulch can also hinder seed germination if you are able to get it into the area.
