How to care for Yellow Thistle

Difficulty

If you're looking for a plant that offers a moderate level of challenge, Yellow Thistle is a great choice to test your gardening skills.

Water

Yellow Thistle should be watered regularly, allowing the soil to dry out between waterings.

Soil

Yellow Thistle 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.

Dormancy

During the cold period, it is common for Yellow Thistle to go dormant, resulting in a slowdown of growth. To accommodate this, waterings should be spaced out more.
