How to keep Polygonum Shastense.
Pruning
Shasta knotweed benefits from strategic pruning in early spring, just before new growth begins. Focus on removing dead stems and thinning the plant to improve airflow and sunlight exposure, which promotes better growth and flowering. Always sterilize your tools before use to prevent the spread of disease.
