How Do You Grow Hydrangeas In Northern Areas?
Although commonly grown in the South, hydrangeas are cold-hardy to USDA growing zone 5. With a little extra care, they can grow in colder northern areas. This old-fashioned bush can grow from 8 to 10 feet tall and produces large pom-pom-like flowers in pink, violet, blue, white or red. For northern climates, select a cold-hardy bush such as Hydrangea paniculate, Praecox hydrangea or Hydrangea arborescens for the best success rate. Grow your hydrangea bush in a location that receives full sun daily in northern areas. Plant the bush on a north- or east-facing side of your home. Water your bush consistently every three days or so, just so the soil stays moist. In warmer months when the temperatures stay above 85 degrees Fahrenheit during the day, water more frequently as needed so the soil does not dry out completely. Water for 30 minutes each time, using a drip irrigation or garden hose with the water trickling out slowly. Feed your hydrangea bush in early June or July once a year only.
