lousewort · Pedicularis sylvatica

Why is my Pedicularis sylvatica getting leggy?

Leggy growth is less common for this plant, as it usually stays low to the ground. It typically happens when the plant is reaching for more light.

Questions people ask

Should I prune the leggy stems?
You can trim back very long stems to encourage a bushier shape. Use clean scissors and cut just above a leaf node.
Can I fix leggy growth by moving it?
Moving it to better light will stop new growth from being leggy. However, the existing long stems will not shrink back to their original size.
