Annual TansyTanacetum annuum

Water consistently once the top 2-3 cm of soil feels dry. Avoid overwatering, as Annual Tansy prefers well-draining soil and can be susceptible to root rot.

Reduce watering frequency during cooler months when growth slows down. Ensure good drainage in pots.

Pinch back young plants to encourage bushier growth. Deadhead spent flowers regularly to promote continuous blooming and prevent self-seeding if not desired.

Light pruning can be done after flowering to maintain shape and tidy up the plant before winter.

Annual Tansy is easily grown from seed sown directly outdoors after the last frost or started indoors a few weeks prior. It can also be propagated by cuttings taken in late spring or early summer, which root readily in moist, well-draining medium.

As an annual, Tanacetum annuum is typically not repotted. If grown in a container, it is usually discarded at the end of its growing season.

For overwintering (though not typical for this annual species), repot into a slightly larger pot with fresh, well-draining potting mix.
