Keep the soil consistently moist, especially during the growing season. Mimulus alatus thrives in wet conditions, so allow the soil to dry out only slightly between waterings.

Water more frequently in hot weather to prevent wilting and ensure adequate hydration for this moisture-loving plant.

Pinch back stems regularly during the growing season to encourage bushier growth and more blooms. Remove spent flowers (deadheading) to promote continuous flowering and maintain a tidy appearance.

Prune lightly in late winter or early spring to remove any dead or damaged wood before new growth begins.

Sharpwing monkeyflower can be easily propagated from seeds sown in early spring, or by taking stem cuttings in late spring or early summer. Cuttings root readily in moist potting mix.

Seedlings may require vernalization for optimal germination. Division of established clumps is also a successful method.

Repot young plants annually in spring to provide fresh soil and more space for root growth. Established plants can be repotted every 2-3 years or when they become root-bound.

Use a well-draining potting mix amended with compost, ensuring the new pot is only slightly larger than the previous one.
