Japanese Knotweed?

Hi there,

I have a Japanese knotweed problem in my area, but am alarmed to see a huge number of seedlings popping up in the garden. I'm not sure they are Japanese Knotweed though, in fact I'm leaning towards thinking theyre not from google searches - can anyone confirm either way?

Here are some of seedlings, one has its first set of proper leaves.

Thanks in advance!!

 

Looks more like sycamore seedlings .Just hoe them off if they are a problem ...

I go along with Dave, sycamore seedlings.

I dont think Jap Knotweed can be spread by seed in the UK.

Not sure if its to do with not enough summer heat or it could be that all the plants in the UK are the same clone.

 

Japanese Knotweed is sterile in this country. It only propagates by vegative rooting. Which is more than enough, thank you.lol lol lol. As has been said, what you have are Sycamore or Maple seedlings.

 

Don't look progressed enough to me to determine whether ash (I get loads of these all over my garden) or sycamore seedlings.

 

My first thought was Sycamore seedlings. There used to be a Sycamore tree in the car park where I worked - every spring, there would be hundreds of these little seedlings sprouting everywhere.

 

I can't see anything there that looks like Japanese Knotweed.
What I am looking at is seedlings - and that is not the mode of spread of knotweed. That comes up as underground shoots from nearby plants.

 

Thanks!

Guys, thank you very much for your quick responses - whether Ash or the more likely sycamore, I am releived! And its interesting to learn about the sterility of the plant here - is that certain with all JK plants in the UK?

May you all have fruitful years, I will be back when the veggies start!
