Scarlet Gilia prefers well-draining soil and moderate watering. Allow the soil to dry slightly between waterings, especially once established. Overwatering can lead to root rot, so ensure good drainage.

Water more frequently during hot, dry periods, but avoid soggy conditions.

Deadheading spent flowers can encourage a longer blooming period and prevent self-seeding if not desired. After flowering, the plant may die back.

You can trim back any dead or unsightly foliage in late winter or early spring before new growth appears.

Scarlet Gilia is easily grown from seed. Sow seeds in fall or early spring. They benefit from stratification; refrigerate seeds in moist sand for 4-6 weeks before sowing.

Transplant seedlings carefully to avoid disturbing their roots.

Scarlet Gilia is typically grown as an annual or short-lived perennial and does not require frequent repotting. If growing in containers, repot only when the plant becomes root-bound, usually every 1-2 years, using a well-draining potting mix.
