Wall Bedstraw prefers consistently moist soil but can tolerate brief periods of dryness. Water thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogging, as this can lead to root rot.

Reduce watering slightly in cooler months when growth slows.

Prune Wall Bedstraw to maintain shape and encourage denser growth, especially if it becomes leggy. Light pruning after flowering can prevent excessive self-seeding.

Remove any dead or unwanted stems at any time of year to improve appearance and air circulation.

Propagate Wall Bedstraw from seeds sown in spring or autumn, or by taking stem cuttings in late spring or early summer. Cuttings can be rooted in moist potting mix or water.

Seeds may require a period of cold stratification for better germination.

Wall Bedstraw generally does not require frequent repotting. If grown in a container and it becomes root-bound, repot into a slightly larger pot in spring using well-draining potting mix.

This plant often thrives when slightly pot-bound, which can encourage flowering.
