Water a young or newly planted Mottled Forget-me-not every 3–5 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Mottled Forget-me-not thrives in full sun to partial shade.

Myosotis discolor tolerates temperatures of 50–75°F. Mottled Forget-me-not prefers humidity levels of 40–60%.

Well-draining, fertile soil with good organic content. Good drainage is essential for Mottled Forget-me-not to prevent waterlogging, which leads to root rot and fungal issues.

Feed Mottled Forget-me-not every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Mottled Forget-me-not can spread to about 1 ft (0.3 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Mottled Forget-me-not while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.

Mottled Forget-me-not is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.
