How To Identify Japanese Knotweed In Spring
Spring is an excellent time to look for young Japanese Knotweed growth in your gardens or commercial property when the invasive weed becomes active.
New growth manifests as delicate, quickly expanding reddish-purple shoots that resemble asparagus spears.
The hollow, bamboo-like stalks can expand up to 10 cm every day. The stem develops a zigzag pattern as the leaves grow on opposite sides of the stem.
Japanese knotweed canes can reach heights of about 3 to 3.5 metres.
It frequently grows as a semi-dense stand of erect stems with 200mm-long shovel-shaped leaves and thick green foliage.
How To Identify Japanese Knotweed In Summer
The mature Japanese Knotweed stems are fully developed with big, green leaves over the summer. Japanese Knotweed produces elongated clusters of creamy-white blooms.
The Japanese Knotweed plants will start to flower as the summer goes on.
Since there are so many flowering plants and weeds in the early summer, it can be difficult to distinguish a Japanese Knotweed infestation from other invasive species.
However, at Japanese Knotweed, our professionals deal with this plant and other invasive species on a year-round basis, and we can assist you in doing so (and other invasive species)
Japanese knotweed canes can reach heights of about 3 to 3.5 metres.
It frequently grows as a semi-dense stand of erect stems with 200mm-long shovel-shaped leaves and beautiful green foliage.
How To Identify Japanese Knotweed In Autumn
In early October, Japanese knotweed blossoms are frequently visible. Some of these will have developed into seeds at the start of autumn (achenes from Russian vine pollen, as there are no male Japanese knotweed plants in the UK).
The seeds and creamy white blooms form distinct panicles. By the end of October, the flowers and seeds will have shed.
Around this time, the dark green leaves of the Japanese knotweed begin to turn yellow and eventually brown. However, if there haven't been any frosts, some plants' leaves may still be present in December, especially if they are shielded from the wind.
Additionally, the stems begin to wither, turn reddish-brown or straw-coloured, and die.
Japanese Knotweed Features in Autumn
Flowers and tiny (5mm) seed casings fall from stem bracts.
The knotweed leaves turn yellow and start to fall; the yellowing may begin at the leaf margins and progress gradually.
Reddening and leaf-shedding stems
How To Identify Japanese Knotweed In Winter
Identifying Japanese Knotweed in the winter can be a little challenging. Knotweed's leaves and flowers are some of the most obvious signs that it is a weed.
This being said, Knotweed can still be identified throughout winter if you know what to look for.
All of the leaves on the Japanese Knotweed will be gone by winter, but the long clustered branches will still be there. These canes will eventually die, become brittle, and turn brown. These stems can remain upright all winter if not disturbed.
However, the weed's 'crown' and rhizome remain dormant during the winter while they wait for spring to return so they may restart the cycle.
Wintertime Japanese knotweed detection can offer the ideal opportunity to address the issue head-on.
Removing the contaminated soil and restoring it when the weed is dormant and there is less activity in the garden or green spaces, your troubles will be forgotten when spring arrives.
How To Identify Japanese Knotweed Roots
You might come across the roots of Japanese knotweed when digging, working in your garden, or working on a commercial site.
Rhizomes, the name for these roots, function like underground stems.
Fresh roots will snap off readily, much like a carrot. The interior is orange or yellow, while the exterior is dark brown.
The root system can spread seven metres horizontally from the plant's visible portion and grow as deep as two metres. The knotweed's ability to spread and its resilience is attributed to these roots.
A single healthy root can give rise to an entirely new plant, which would bring back the infection.
Identifying Japanese Knotweed Shoots
Japanese knotweed shoots have a cane-like appearance and develop in distinct segments with a hollow centre.
The following characteristics of Japanese Knotweed shoots should be noted:
They can reach heights of up to 2-3 metres, and the stems are hollow.
Red in the springtime.
Green throughout the summer.
Similar to bamboo shoots in appearance.
Identifying Japanese Knotweed Stems
The knotweed stems resemble bamboo and have noticeable nodes/rings and purple flecks.
Alternating leaves emerge from the stem nodes, forming a "zig-zag" pattern at the top.
Stems significantly thinner and shorter than mature stems result from immature development from small crowns, fragmented or disturbed rhizomes, and locations where mowing or other techniques to lower plant vigour have been used.
Mature growth produces 2m to 3m tall thickets are produced. Adult stems are hollow and can be easily snapped.
