Winter Protection for Gardenias: Using Frost Cloth Only When Temperatures Drop to the Teens

Q: Best way to protect a 3-year-old gardenia from winter? If I wrap in burlap until spring, would it help?

Generally, gardenias don't need protection unless temperatures go into the teens overnight. Some varieties are hardier: 'Kleim's Hardy' and 'Daisy' more cold-tolerant; 'August Beauty' less tolerant but more attractive flowers. If protecting, buy floating row cover (frost cloth). When lows forecast, cover plant to ground on all sides, anchoring edges with stones or firewood. Leave until weather moderates. Do NOT keep cover on all winter.
