Hi,
I'm trying to work out what THIS pesky thing is that keeps taking over my 'garden'.
Does anyone know what it is? And how best to get rid of it?
I plan to put weed matting down on the tiers that are hidden underneath it...
Your pesky plant looks like a form of Tradescantia and pesky is a good description of it. It grows like crazy, particularly in the the warm humid conditions of this summer and is really difficult to get rid of.
The best thing is to dig it out, making sure that you remove all the roots because new plants can regrow from any piece of plant left behind. You can spray with a glyphosate based herbicide but roots do develop at the leaf nodes which means you need to have to spray all upper parts of the plants. Repeat every 1-2 months, it may take 3 to times to kill it all.
If the weed is growing amongst your plants you may want to remove as much of creeper as possible and then use a herbicide brush or wand.
I have tried covering it with black plastic and newspaper without any success, unfortunately herbicides seem the only solution
