Water consistently when the top 2-3 cm of soil feel dry. Linaria supina prefers moderate moisture and dislikes waterlogged conditions. Reduce watering in winter when the plant is dormant to prevent root rot.

Ensure good drainage to keep the roots healthy.

Deadhead spent flowers regularly to encourage continuous blooming and prevent self-seeding if unwanted. Lightly trim back leggy stems in late spring or early summer to maintain a compact shape and promote bushier growth.

Remove any dead or diseased foliage promptly.

Linaria supina is easily propagated by seeds sown in early spring or autumn. It can also be propagated by stem cuttings taken in late spring or early summer.

Cuttings should be placed in well-draining soil and kept moist until established.

Repot seedlings or young plants as needed, typically every 1-2 years, when they become root-bound. Use a well-draining potting mix. Choose a pot that is only slightly larger than the current one.

Repot in spring before active growth begins.
