The knotweed (Fallopia or Polygonum aubertii) is actually a very vigorous and almost indestructible climbing plant that does not require too much care - apart from regular and vigorous pruning, so that the plant does not overgrow the entire garden in no time at all. But even the robust knotweed occasionally shows signs of a shortage.
Yellow leaves on knotweed can be a sign of nutrient deficiency
Yellow leaves indicate a lack of water and nutrients
Knotweed cultivated in tubs, balcony boxes (€109.00) or other planters in particular quickly suffer from a lack of space due to their strong growth - the normally very deep, widely branched roots cannot spread out in line with above-ground growth, so that water and nutrients cannot can be consumed in sufficient quantity. A deficiency occurs, which is quickly reflected in the yellowing of the leaves.

On the other hand, the only thing that helps is to cut back the knotweed and, if possible, put it in a larger pot. The planter can't be big or deep enough, although the plant feels most comfortable in the wild anyway - i.e. planted out in the garden.
tips and tricks
If your knotweed develops yellow leaves in the fall, this is most likely normal as it is a deciduous plant.
