Do Eustoma flowers need full sun?
Eustoma grandiflorum, or Lisianthus, is a flowering biennial that will survive the winter temperatures of USDA Zones 8-10, but rather than being considered a perennial, it is more typically grown as an annual. It does best in average, moist, well-drained soil with full morning sun and afternoon shade. Deadheading Shasta daisies regularly will prolong bloom time. Learn more about why and when to deadhead your flowers.Regular deadheading (1-2 times a week) encourages the plants to put their energy into creating continuous growth and more blooms. Deadheading is a simple task, that only requires you to pinch or cut off the flower stem below the spent bloom, and just above the newest set of healthy leaves.Pruning: Deadheading lisianthus encourages more blooms. In areas where it can be grown as a perennial, cut it back to the ground in winter and cover it with mulch. In extremely low temperatures, a row cover is used for added protection.
