Water Modiola caroliniana regularly, especially during its active growth period. Allow the top 2-3 cm of soil to dry out between waterings to prevent waterlogging, which can lead to root rot.
Reduce watering in cooler months when growth slows.

Watering, pruning, propagation, and repotting details from plant data
Water Modiola caroliniana regularly, especially during its active growth period. Allow the top 2-3 cm of soil to dry out between waterings to prevent waterlogging, which can lead to root rot.
Reduce watering in cooler months when growth slows.
Prune Modiola caroliniana lightly after flowering to maintain its shape and encourage bushier growth. Remove any dead, damaged, or crossing stems.
Occasional pinching back of the tips during the growing season can promote a more compact form.
Propagate Modiola caroliniana from seeds sown in spring or early summer. Seeds can be surface sown in a well-draining compost.
Alternatively, take stem cuttings in late spring or early summer and root them in a moist, well-draining medium.
Repot Modiola caroliniana every 1-2 years, or when it becomes root-bound. Spring is the ideal time for repotting.
Use a well-draining potting mix and a pot that is only slightly larger than the current one to avoid overwatering.
