Agapanthus growing out of control?

Agapanthus is not really a weed, of course. It’s more of an ornamental flower, and a pretty nice one too, in its place. It is, for example, better able than almost anything else to handle the carbon monoxide laden atmosphere in the middle of a busy motorway. That’s why we see so many planted there, and looking very pretty too. The problem, however, is that agapanthus often does not stay in its place, and even when it does stay it can be just like an unwelcome guest; it’s damned hard to get rid of when you’ve had about enough of it!

Most authorities confirm that agapanthus is very difficult to get rid of, even with powerful sprays. Common recommendations are for glyphosate, metsulfuron-methyl (MSF600) and triclopyr (Triclo).

Our experience is that they all will work, but that glyphosate and MSF600 are more effective at some times than at others. Some customers have had excellent results with these products, and others have been disappointed, for reasons that neither they nor we can explain.

We, therefore, have only one recommendation to make:

Triclo at 6ml/L water & SuperWetter 1ml/L in a knapsack or 300ml Triclo /100L water, with SuperWetter at 100ml/100L water in a handgun is the way to go.  A follow up treatment will likely be required.

Results with Triclo have been excellent, and appear to be far more reliable than any other option.
