easy to growPlanting & Care
If growing outdoors from the off then it is best to sow Knotweed and other Polygonum species outside just after the last frost of spring; once sown lightly cover the Knotweed seeds with topsoil.
The plants prefer to grow in a partially shaded part of the garden and like to have a moist soil of pH 6 to 7.5. Even though the soil should be moist it is important that Knotweed grows in areas of good drainage.Sunlight:

- Knotweed and other Polygonum plant genus members like to grow in a moist garden soil so keep well watered.
- The vine varieties of Polygonum should be pruned heavily at the start of spring to prevent scrawny growth and make them more attractive.
- Once flowering has finished cut back the stems (usually in the autumn).
- If you require more plants then they can be propagated by division in the autumn.
