How to grow:
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. 
If starting Polygonum indoors then do so about three weeks before you expect the last frost. The seeds can take anything from 3 to 8 weeks to germinate at a temperature of 21 to 24 degrees centigrade. Once ready, transplant the seedlings at a spacing of 20 to 30cm (small Polygonum species); 30 to 60cm (medium size) or 70cm to 1.2M (larger Polygonum varieties).
