The Hydrangea flowers are truly beautiful to look at.

Caring for Hydrangea Plants

Easy to care for

Caring for Hydrangea plants is not as much of a tough task as it is often made out to be. Just make sure that you have all the necessary information on the kind of Hydrangea that you are adding to the household. Once you have that, here are some basic care tips that can make caring for Hydrangea plants an effortless task.

  • The Ideal Planter: Hydrangeas can very well be grown in containers and planters. However, make sure that the planter is neither too large nor too small as per the current size of the plant. Also, make sure that there are enough drainage holes to flush out the excess water from the plant that would otherwise pose a serious threat to the growth of the plant.
  • Potting Mix for the Plant:Hydrangeas plants are fuss-free plants when it comes to deciding on the kind of soil for growing the plant in. However, the plant best prefers growing in soil that is rich in organic matter and also drains well. Adding some compost to the soil mix also helps to boost the growth of the plant.
  • Meeting the Light Needs:The light needs of the Hydrangea plants can differ from variety to variety. Certain varieties prefer the bright sunlight while others grow well in partial shade. However, make sure that the plant is not exposed to the direct rays of the sun. If possible, place the plant in such a spot that receives sunlight but also cools off in the afternoon shade.
  • Watering the Plant: Adequately watering the plant is an important step in caring for Hydrangea plants. Remember to water the plant deeply once every week or so. If possible, use distilled water for watering as the tap water consists of chlorine and other chemicals that might cause harm to the plant. Make sure that the soil does not dry out and also that you do not over-water the plant.
  • Temperature and Humidity: Most of the Hydrangea varieties dislike being exposed to extremely hot conditions. This makes it necessary for the plant to be placed at a spot that receives sunlight but is also cooled off by the afternoon shade. Hydrangeas do well in temperatures between 50 to 60 degrees Fahrenheit and require a humidifier only if the conditions are extremely dry.
  • Fertilizing the Plant:Fertilizing the plant is necessary to make sure that the plant is being met with all its nutrient requirements. For Hydrangea plants, use water-soluble fertilizers and dilute them to half their strengths. Feed the plant once every week when it is blooming. Once the plant is done blooming, it is enough to fertilize it once every month.
  • Pruning the Plant: The pruning season and the pruning needs of the Hydrangea plants also differ from variety to variety. Some require pruning in the late summer while others require the same in the early spring season. Just gather the necessary information on your variety and make sure that you do not end up over-pruning the plant.
