Watering, pruning, propagation, and repotting details from plant data
Scarlet monkeyflower thrives in consistently moist soil. Water regularly, especially during dry periods, to keep the soil damp but not waterlogged. Ensure good drainage to prevent root rot.
Overwatering can be as detrimental as underwatering.
Deadhead spent flowers regularly to promote continuous blooming and prevent seed formation. In late autumn, after flowering, prune back the plant by about one-third to maintain a tidy shape and encourage new growth in the spring.
Scarlet monkeyflower is easily propagated from seed sown in early spring or late autumn. Cuttings can also be taken from softwood in late spring or semi-hardwood in mid-summer. Both methods generally root well.
Repot seedlings or young plants when their roots begin to fill the pot, typically in spring. Established plants can remain in their pots for several years.
Choose a pot with adequate drainage and use a well-draining, humus-rich potting mix.
