With its straightforward care requirements, Square Stalked Willowherb is a hassle-free plant that anyone can enjoy.

Square Stalked Willowherb should be watered regularly, allowing the soil to dry out between waterings.

Square Stalked Willowherb loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.
