Hi,

While looking at my pond last night I spotted some water fern, which I read is highly invasive and will take over if not removed asap. My pond has been there since May and hasn't had anything added for a couple of months.

Is it possible that this came in on birds or even animals for that matter? It's weird that it seems to have suddenly appeared - not in huge lumps but only just become noticeable. Does it perhaps sit dormant and this time of year is ideal conditions?

Thanks for any ideas
