SPOT IT EARLY!
Spring is the easiest and most affordable time of the year to treat Japanese knotweed. It is crucial that you know what signs to look out for to save you money.
If they haven’t already, Japanese knotweed stems will soon begin sprouting, after lying dormant through the winter. Unfortunately, due to changing temperatures. Not only are we seeing a rise in the amounts of Japanese knotweed, we are also witnessing sprouting occurring earlier every year.
Identification in the early months of spring can be difficult, however a trained professional will be able to let you know if you have Japanese knotweed within one site visit.
Japanese Knotweed During Early Spring:
Japanese knotweed can grow 2cm a day: it will develop from red/purple shoots to fleshy green asparagus-like stems of 1 to 4cm, into dense stands of bamboo-like stalks closer by the summer which can reach heights of 3m, growing upwards of 70cm every week.
The flowers of Japanese knotweed wont emerge until late summer; this is why it is so important to know what Japanese knotweed looks like through all stages, to not just look for the large green heart shaped leaves, but for the stems, to ensure early identification and treatment.
Even after the leaves develop over the summer months, Japanese knotweed spreads predominantly underground, in which the rhizomes (roots) can spread to 7m outwards and 3m deep. These rhizomes can lie dormant, but alive, through the winter and are the reason Japanese knotweed can cause so much damage to your property.
The fierce spread of Japanese knotweed means that there are more and more cases every year. However, there is good news! – long term damage is avoidable, if you look out for the signs and organise treatment straight away.
