Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Keep the soil consistently moist but not waterlogged, especially during active growth. Reduce watering significantly in fall and winter to mimic natural dormancy.
Allow the top centimeter of soil to dry out slightly between waterings during the growing season for best results.
Prune to maintain shape and remove any dead or damaged stems. Pinch back young plants to encourage bushier growth.
Deadhead spent flowers to prevent seed formation and encourage further blooming, especially if you want to prolong the flowering season.
Propagate by seed, sown in spring or autumn. Seeds may require a period of cold stratification. Division of established plants is also possible in spring.
Ensure new seedlings or divisions are kept moist and in a bright location.
Repot young plants annually in spring. Mature plants can be repotted every 2-3 years, or when root-bound. Use a well-draining potting mix.
Ensure the new pot is only slightly larger than the previous one to avoid overwatering issues.
