Before you start planting hydrangeas, there are a few factors you need to take into account. These include:

  • The size of your hydrangea at maturity: Different hydrangea varieties grow to different sizes, so you need to take this into account when planning your planting.
  • The soil quality: Hydrangeas prefer acidic soil, so if your soil is alkaline, you may need to take steps to adjust the pH.
  • The lighting conditions: Hydrangeas prefer partial shade, so you need to choose a planting spot that receives some direct sunlight but is also shaded for part of the day.
  • The climate: Hydrangeas prefer mild climates with moderate humidity, so if you live in a hot or dry area, you may need to take extra care when planting and caring for your hydrangeas.

Once you’ve taken these factors into account, it’s time to decide on the spacing of your hydrangeas. As a general rule, you should space hydrangeas around 3 to 10 feet apart, depending on the variety and size of the plant.

If you’re planting hydrangeas as a hedge or border, you can space them closer together – around 2 to 3 feet apart – to create a denser effect. However, if you’re planting hydrangeas as standalone specimens, you should space them further apart to give them room to grow.

  • Make sure the hole you dig is at least twice as wide as the root ball of your plant.
  • Mix some organic matter – such as compost or peat moss – into the soil to improve its quality.
  • Water your hydrangeas regularly, especially during hot weather.
  • Fertilize your hydrangeas once a year, in the spring or fall.
  • Prune your hydrangeas in the late winter or early spring, just before new growth begins.
