Answer: You must be taking good care of your plant since it is setting lots of buds. Keep in mind that mandevilla really likes heat and moisture and high humidity when it is in bloom. Based on your zip code there have been some cooler nights in the mid fifties recently in your area recently, make sure the plant is not getting colder than 55 degrees. Also be sure you are keeping the soil evenly moist. If kept too dry, the buds will dry out. Good luck with your mandevilla!
