The latest hotspots for Japanese knotweed in Suffolk have been revealed.

Japanese knotweed can grow up to four inches a day and forms dense thickets which can kill native plant species.

As it is now spring this can grow at a rate of 10cm a day and is at its most visible between February and November.

Data from Environet shows which areas are currently having a break out of the species.

Ipswich has the most amount with 54 occurrences within 4km, which is the same amount as it was in November 2024. 

Earlier in 2024 it was higher at 57 occurrences.

Twenty cases were reported in Stowmarket and near Needham Market.

There are seven occurrences within 4km in Sudbury and Bury St Edmunds, which is the same as in November.

In Haverhill there are eight occurrences within 4km, whereas in Woodbridge there are six occurrences within 4km.

Environet estimates about 5% of homes across the UK are currently affected by Japanese knotweed, either directly or neighbouring an affected property.
