Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Sea Mayweed prefers consistently moist soil but can tolerate some dryness once established. Water deeply when the top 2-3 cm of soil feels dry. Avoid waterlogging, especially in winter, as this can lead to root rot.
Reduce watering during cooler months if the plant is dormant.
Pruning is primarily for tidiness and to encourage bushier growth and more flowers. Deadhead spent blooms regularly to prevent self-seeding and prolong flowering.
Light trimming after the main flowering period can help maintain a compact shape and prevent it from becoming leggy.
Sea Mayweed is easily propagated from seeds sown in early spring, either directly outdoors or indoors a few weeks prior. It can also be propagated from cuttings taken in late spring or early summer.
These cuttings root readily in moist, well-draining soil.
As a generally low-maintenance annual or short-lived perennial, Sea Mayweed rarely needs repotting.
If grown in containers, repotting can occur in spring if the plant becomes root-bound, moving it to a slightly larger pot with fresh, well-draining potting mix. Ensure the new pot has adequate drainage holes.
