Water regularly to keep the soil consistently moist, especially during dry periods. Avoid waterlogging, as Stellaria graminea prefers well-drained soil.

Check the soil moisture regularly and water when the top few centimeters feel dry to the touch. In hotter weather, more frequent watering may be necessary.

Pruning is not typically required for Stellaria graminea, as it is a low-growing, self-limiting plant.

However, you can trim it back after flowering to maintain a tidier appearance or to prevent excessive self-seeding if desired. This also encourages denser growth.

Stellaria graminea is easily propagated by seed sown in autumn or early spring. It also readily self-seeds. Division of established clumps in spring or autumn is another effective method.

Plant seeds or divisions in well-draining soil in a suitable location.

Repotting is generally not necessary for Stellaria graminea, as it is often grown in beds or borders and spreads naturally.

If grown in containers, repotting can be done in spring when the plant shows signs of overcrowding or has outgrown its pot. Use fresh potting mix.
