April Showers

Categories: Tags:

April Showers are an invasive weeds best friend! This influx of moisture gives any invasive weed, especially Japanese knotweed, an extra burst of energy and if it hasn’t already sprouted it will be very shortly.

As specialists of Japanese knotweed and invasive weeds as a whole, we can spot an infestation quite easily however most home/land owners will mistake invasive weeds for more friendly plants/weeds and ignore the early signs of an infestation.

We’ve posted previously about what to look out for (pinkish coloured asparagus-looking buds sprouting up from soil/tarmac/anything really) and there’s an example below for you to see:

However, this post is here to assure you that at this stage, there’s not really much you can do apart from calling a specialist like ourselves. You can find out more about our survey and treatment processes on this website. We’re always happy to chat about any concerns or questions so please feel free to call us anytime!

A lot of our clients are often surprised when we don’t treat their infestation until May/June time and this is because this is the optimum time to attack the weed and halt it’s growth cycle. The first treatment will kill a large proportion of the visible growth and stop any further spreading for the time being. Re-growth is likely to occur in later summer when a second treatment would be applied to once again attack the weed’s rhizome system and kill the visible part of the weed, keeping the visible growth to minimum to protect surrounding flora and land and of course to inhibit any further spreading.

The chemical method for treatment (the only one we use) can be seen as lengthy but it is by far the cheapest method and has many other benefits, all of which can be read about on our treatment page below:


As always, please feel free to contact us via the contact form or by giving us a call and we can have a chat.

Please feel free to comment on this post also, it’s always good to hear from you all.

Thank you for reading!

That’s right, early sightings of Japanese knotweed shoots have already been spotted in Scotland. That means it’ll soon be rearing its ugly head down here too. I’ve put this guide together so you can know what to look for and what to do if you do spot the pesky weed.

When Japanese knotweed grows its looks just like asparagus sticking out of the ground with a reddish colouring. There can be 1 stand or 100 and will start off pretty short but will grow rapidly.

We’d normally recommend checking any areas of land near railway lines, water or waste sites but these days Japanese knotweed will grow just about anywhere it can, so be vigilant and look out for it among your every day plants/shrubs, in your gardens and local areas.

You can see an image of Japanese knotweed sprouting below:

If you do spot this on your land:

1. Do not attempt to remove, cut, stamp or kill it.
2. Try and isolate the area or mark it out for reference.
3. Don’t disturb the soil/ground around the growth and if possible, any land within 7 meters.
4. CONTACT A PROFESSIONAL CONTRACTOR such as Pennine Knotweed Removal (us) and arrange for a survey to be conducted ASAP.

If the weed is on neighbouring land then you should inform the owner ASAP and then point them in our direction.

We’ve dealt with many cases of Japanese knotweed and as long as it’s being dealt with, there is absolutely nothing to worry about!

I hope this guide helps and if you do need to contact us, please call 0800 138 3143.

On our The Law page you can find information on how to deal with private land owners if Japanese knotweed is present on neighbouring land. However, the best course of action is to have a qualified, specialist contractor visit the property to conduct a survey and then provide a knotweed management programme and guarantee.

This will, in most cases, put banks/lenders mind’s at rest and allow the sale of the property to go through!

Dangers (and Do’s and Don’ts)

Possible Japanese Knotweed Damage:

  • Weakening of house and building foundations
  • Integral damage of roads, pathways and paved areas
  • Damage to free standing structures such as walls and pillars
  • Destruction of native wild life habitats
  • Unseen damage to underground pipes, drains and ducting

Knotweed Do’s and Don’ts


  • Cut down and place Japanese Knotweed in other areas. IT WILL SPREAD
  • Walk/cultivate/disturb around the area Japanese knotweed is located/suspected. IT WILL SPREAD
  • Attempt to burn Japanese Knotweed unless completely dried out and removed from the area of growth. IT WILL SPREAD
  • Attempt to remove Japanese Knotweed from river and stream banks. Water is one of its favourite modes of transport. You need professional help! IT WILL SPREAD
  • Use unlicensed chemicals or herbicides either near water or other plants, grasses or wildlife. You’ll be breaking the law and may kill everything BUT the Knotweed.


  • Check regularly for the appearance of Knotweed shoots, especially if you live near a waterway.
  • Call us for advice on the correct treatment and disposal of Knotweed.
  • Treat knotweed immediately. The sooner we can catch it, the less chance it will spread and the lower the cost is for eradicating it.
  • Try to isolate the Knotweed before treatment and avoid disturbing the soil around the plant (disturbing the soil encourages growth.)
