Care Instructions
Purple Loosestrife thrives in reliably moist soil or shallow pond margins, in full sun.
Plant directly in damp ground or in a pond basket, and mulch with compost in spring.
After flowering, cut back faded stems in late summer or autumn. Divide clumps in spring to propagate.
Repotting Instructions
Can also be planted in very wet soil – do not allow to dry out.
9cm marginal plants require potting into a mesh basket. Place in a pond no deeper than 1/3 maximum recommended planting depth to allow the plants to establish.
1ltr marginal plants do not require repotting but will benefit from a bigger basket, there is no need to remove the mesh basket. Place in pond no deeper than 1/2 maximum recommended planting depth to allow the plants to establish. Plants over 60cm height growth will benefit from repotting into a larger mesh basket or should be planted in gravel to prevent them from falling over in a breeze.
3ltr and 5ltr plants do not require repotting; there is no need to remove the mesh basket. Place on the shelf of the pond at the required depth.
