South Ayrshire residents have been warned that now is the time to take action against the destructive plant Japanese Knotweed.

The plant, known for its fast and aggressive growth, is in its peak flowering season from late summer through August and early September.

Growing up to three metres tall with roots reaching down 20 metres, the plant is known for wreaking havoc on homeowners, destroying pipework, drains and even weakening building foundations.

According to invasive plant specialist Environet UK, more than ten cases have been identified across the region.

Three of these are within four kilometres of the Troon area, with another three in the Ayr/Prestwick area.

Cases are also noted to the south of Alloway, alongside hotspots to the south of Maybole and Girvan.

Some parts of Glasgow have recorded 138 sightings of the plant within 4km. While in London, some parts have recorded 265 sightings of knotweed.

While it hibernates over Winter, from March and April it returns and can destroy pipework, drains and can even weaken building foundations.

According to experts Japanese Knotweed Specialists, now is the time to act.

A spokesperson said: "Japanese Knotweed is most visible and active during the flowering season. If not controlled, it can quickly take over gardens and cause long-term damage due to its aggressive nature and strong desire to reproduce."

They said three critical indicators of Japanese Knotweed to look out for in the summer months are:

White to cream-coloured flowers

The flowers grow in clusters, known as panicles, which can be 6 to 15 cm long and feathery in appearance.

Heart-shaped leaves

The leaves are broad and heart-shaped, with a pointed tip. They range from 7 to 14 cm long and often grow in an alternate pattern along the stem.

Hollow, bamboo-like stems

The plant's hollow stems, similar to bamboo's, can be green, red, or purple. It has a zigzag growth pattern and can reach 3 to 4 metres (10 to 13 feet). It can form dense thickets that are difficult to control and penetrate.
