For planting melolobium, select well-draining soil, as proper drainage is crucial to prevent root rot. These plants typically prefer full sun exposure but can tolerate partial shade. Keeping the soil consistently moist, especially during the growing season, supports healthy growth. Amend the soil with organic matter to improve fertility before planting. Space the melolobium according to species size, allowing room for spread. Mulch around the base to retain moisture and suppress weeds. While melolobium can adapt to a range of conditions, each species may have unique requirements.
